Detailed notes

## Background Published on YouTube on February 26, 2022, by the LockPickingLawyer, this video documents an attempt to defeat a viewer-submitted lock sealed with an anti-tamper sticker. The show notes provide a link directing viewers to Covert Instruments.

## TL;DR Addressing a challenge sent by a viewer named Ben from Oakland, the LockPickingLawyer sets out to pick an Abus padlock whose keyway is covered by a fragile, tamper-evident holographic seal. Rather than destroying the seal, he uses denatured alcohol, a scalpel, and tweezers to non-destructively peel off the sticker intact. He then picks the Abus Plus core by tensioning directly off disc two to bypass the front butterfly disc, opening the lock well within Ben's three-minute target. To conclude, he reapplies the intact sticker before tearing it off dry with his fingernails to prove its tamper-evident foil shreds under normal physical attacks.

## Atmosphere & style The presentation carries a playful, slightly conspiratorial charm as the host candidly announces his plan to cheat the challenge while maintaining his signature quiet composure. The mood briefly touches on the eerie reality of internet fame when he recounts discovering a live tracking device in his fan mail, before shifting back into surgical precision with liquid solvent, a scalpel, and custom picks. It feels like watching a calm, clinical masterclass in physical security evasion, ending on a note of wry satisfaction when the exploit succeeds without a hitch.

## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=0s) The Challenge from Ben and the Tracking Device Incident

The LockPickingLawyer opens the video with an upfront confession: he intends to cheat on an incoming viewer challenge, explaining that doing so will be entertaining and will allow him to demonstrate a technique he has never shown on camera before. He introduces the challenge by reading a letter sent by a viewer named Ben from Oakland. In the letter, Ben acknowledges past email correspondence regarding the channel's policy against accepting sealed packages. The LockPickingLawyer pauses on this detail to share an unsettling personal anecdote: an overzealous viewer recently mailed an active tracking device to his P.O. Box, though fortunately he discovered it while still inside the post office. Ben’s letter sympathizes with this incident, remarking on the creepy invasion of privacy by referencing Eminem’s song “Stan,” a pop-culture nod the LockPickingLawyer happily confirms he caught.

D --> E H --> I ```

To circumvent the ban on mystery-sealed boxes while still creating a verifiable blind challenge, Ben devised an alternative approach: instead of wrapping the entire padlock, he sealed the keyhole itself with a specialized holographic tamper-evident sticker. Ben explains in his note that his workplace uses these exact stickers over assembly screws on hardware because they are designed to fracture and disintegrate if anyone attempts to peel them off. The challenge rule set is simple: the LockPickingLawyer must beat a target time of three minutes—the time it took him to pick an Abus Plus core in video 1398. If he beats the clock, Ben promises to mail the keys; if he fails, the lock must be returned unpicked. Ben candidly adds that he hopes the host fails because the lock was expensive and he wants to put it to use. The LockPickingLawyer clarifies that he already owns this model and plans to return it regardless, remarking wryly: “Then I already have at least one of these, so I'll send it back either way, especially because after this video, I doubt you'll trust the result anyway.”

- Ben's target benchmark: Beat the 3-minute pick time established in LockPickingLawyer video 1398. - Incident report: A tracking device sent by a fan was caught by the LockPickingLawyer inside the post office facility before reaching his home or workshop. - Challenge terms: Keys awarded if opened within 3 minutes; lock returned if the attempt exceeds the limit or fails.

[01:50](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=110s) Defeating the Tamper-Evident Holographic Seal

To defeat the anti-tamper mechanism without invalidating the seal, the LockPickingLawyer prepares a dedicated workstation featuring a protective metal plate on his desk to guard against chemical drips, a syringe filled with solvent, a precision scalpel, fine tweezers, and a magnet mounted under the padlock to tilt the keyway toward the camera. His objective is to lift the tamper sticker completely intact, pick the padlock open, and stick the original seal back down over the cylinder as though it was never disturbed.

He dispenses a measured bead of solvent along the border of the holographic sticker to soften the underlying adhesive bond. Once the chemical begins to penetrate, he eases the tip of the scalpel blade underneath one corner. As the sticker begins to separate from the metal face, he floods the interface with additional liquid from the syringe, withdraws the scalpel, and takes hold of the freed foil with tweezers. Pulling back with steady, gentle pressure while continually bathing the underside in liquid prevents the fragile frangible layers from shearing apart. He reveals his chemical of choice during the process: “By the way, the solvent is denatured alcohol, there's no need to use anything more aggressive for stickers like this.” Once peeled off cleanly, the pristine sticker is laid aside so the alcohol can evaporate, which allows the solvent-softened adhesive to regain its natural tackiness for later reapplication.

- Workstation setup: Benchtop metal plate, liquid syringe, fine scalpel, tweezers, and a magnetic base. - Chemical agent: Denatured alcohol, chosen because it dissolves pressure-sensitive adhesive bonds without melting or distorting typical holographic films. - Preservation tactic: Evaporation allows the adhesive layer to return to a tacky state rather than washing it away completely.

[03:23](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=203s) Tensioning Disc Two and Picking the Abus Lock

With the keyhole unobstructed, the LockPickingLawyer initiates the picking process by rotating every disc inside the Abus Plus core as far clockwise as possible. Rather than using the traditional method of tensioning off disc number one, he employs a custom picking technique he recently developed. He selects a disc detainer pick equipped with extended tensioning prongs designed to reach past the first slot and tension directly against disc number two. He explains the mechanical theory behind this approach: the first position houses a butterfly disc intended to hamper picking, and tensioning off disc two completely bypasses that security feature. While this bypass only functions on roughly one-third of these locks—specifically those cut with a number 0 or number 1 depth at the second position—it allows an exceptionally rapid open whenever the code complies. If the cut is incompatible, he can simply fall back to conventional tensioning.

Tensioning disc two immediately yields clean mechanical feedback, confirming the lock possesses a compatible cut. The LockPickingLawyer systematically works down the disc stack, initially placing each disc into a gate regardless of whether it is true or false. After an initial pass establishes gate placement with distinct tactile clicks, he returns to the front of the stack to test disc movement and weed out false gates from true gates. Disc three is identified and aligned into a true gate, followed by individual adjustments along the remaining discs. Working back and forth through the stack, he identifies several deep false gates and navigates the discs into their proper true gates until the sidebar drops into place and the core rotates freely to open the lock. Although he did not run an active stopwatch on screen, the pick takes well under the three-minute threshold set by Ben.

- Picking strategy: Bypassing the butterfly disc at position one by tensioning directly off disc two with extended prongs. - Probability of bypass success: Effective on approximately 33% (one-third) of Abus locks, dependent on a #0 or #1 cut at position two. - Picking stages: First pass brings all discs into any gate; second pass isolates true gates from false gates based on rotational play.

[05:43](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=343s) Reapplying and Testing the Tamper Seal

With the lock open and the shackle freed, the LockPickingLawyer moves to the final phase of the demonstration: restoring the tamper seal to simulate a completely untouched unit. Having given the denatured alcohol sufficient time to evaporate from the backing, he uses his tweezers to position the intact holographic sticker back over the core. He presses it firmly down against the metal face of the padlock, confirming that the adhesive has dried and re-bonded cleanly with no outward indication of tampering or prying.

To prove the genuine integrity of the sticker’s tamper-evident construction, he attempts to peel it off with his bare fingers now that the solvent is gone. As soon as he gets a fingernail under the edge and pulls dry, the fragile material tears violently, delaminating into shredded, jagged fragments across the face of the lock. The demonstration confirms that the sticker performs exactly as engineered under normal physical attacks, and was only defeated because chemical solvent neutralized the frangible adhesive bond during the initial removal. He wraps up the demonstration pleased with how smoothly the exploit succeeded, declaring: “Okay folks, I could not have asked for this to play out any better.”

- Reapplication result: The solvent-treated sticker adhered smoothly with full optical clarity and no visible stress marks. - Destructive validation: Without solvent, a manual peel attempt caused the holographic seal to fragment instantly, leaving tamper evidence on the lock face. - Outcome: Challenge beaten under time limit, bypass demonstrated, and lock returned to the viewer.

Reading summary

The LockPickingLawyer demonstrates how solvent-based removal can completely circumvent a frangible tamper-evident seal, allowing an Abus Plus padlock to be picked and resealed without visual evidence of access. Viewer Challenge Constraints and Anti-Tamper Security (0:00) A viewer named Ben devised a blind challenge to test whether the LockPickingLawyer could pick an Abus Plus padlock in under three minutes—matching the benchmark from video 1398. Because channel policy prohibits receiving sealed mystery boxes following an incident where an overzealous viewer mailed an active tracking device to the host's P.O. Box, Ben instead secured the lock's keyway directly with a commercial holographic tamper-evident sticker. These foil stickers are engineered to shred and delaminate if peeled manually, serving in workplace environments to secure assembly screws against unauthorized access. Bypassing Frangible Foil via Denatured Alcohol (1:50) Rather than picking directly through or visibly destroying the seal, the LockPickingLawyer executed a non-destructive removal using denatured alcohol, a scalpel, and tweezers on a metal-protected workstation. By dispensing the solvent along the border and gently easing the scalpel beneath the edge, the liquid softened the pressure-sensitive adhesive without dissolving or distorting the holographic film. Continual flooding with alcohol allowed the fragile sticker to be peeled off in one intact piece. Setting it aside permitted the alcohol to evaporate, restoring the adhesive layer's natural tack for subsequent reapplication. Core Picking via Disc Two Tensioning (3:23) With the keyway accessible, all discs were rotated fully clockwise. The host bypassed the anti-picking butterfly disc located at position one by employing a disc detainer pick with extended tensioning prongs to tension directly off disc two. This exploit functions on approximately one-third of Abus locks that possess a number 0 or number 1 cut at that position. Once rotation confirmed a compatible cut, the discs were placed into gates in an initial pass, followed by a second pass to isolate true gates from false gates based on rotational movement. The sidebar dropped and unlocked the core well within the three-minute limit. Reapplication and Destructive Seal Validation (5:43) After opening the lock, the host aligned the intact sticker back over the keyhole and pressed it down. The evaporated adhesive resealed cleanly with no optical distortion or visible marks of tampering. To confirm the seal's baseline efficacy, the host then attempted to remove the dry sticker using only his fingernails; without solvent, the frangible foil immediately tore and shredded across the metal face. The test verified that the seal functions against standard manual peeling but remains vulnerable to solvent-assisted adhesive release. The demonstration shows that physical tamper-evident seals provide unreliable proof of non-entry when adhesive bonds can be neutralized chemically, though the host noted he would return the lock to the viewer regardless.

精炼阅读摘要

LockPickingLawyer 演示了如何利用化学溶剂无损剥离工业级防篡改全息贴纸，并结合绕过蝴蝶盘防撬机制的二号盘张紧技术快速开启 Abus Plus 锁芯，从而在不破坏封条完整性的前提下达成挑战要求。包裹安全顾虑与钥匙孔贴纸挑战的由来 (0:00) 该挑战源于加州奥克兰观众 Ben 发送的 Abus 挂锁。LockPickingLawyer 解释称，频道此前之所以制定拒绝接收密封包裹的政策，是因为近期曾有观众向其邮政信箱寄送过一个处于激活状态的追踪装置，所幸该设备在邮局设施内即被当场截获。为了在遵守“不接收暗盒包裹”规定的同时建立盲测条件，Ben 选择直接在挂锁钥匙孔处粘贴一张工作场所用于固定硬件装配螺丝的工业级防篡改全息贴纸。根据挑战规则，LockPickingLawyer 必须打破其在第 1398 期视频中创下的 3 分钟 Abus Plus 锁芯开启纪录；若未能在时限内开启，则须将未开封的挂锁寄回。LockPickingLawyer 指出自己已拥有该型号挂锁，无论挑战成功与否都会将其归还给观众。采用变性乙醇无损剥离防篡改标签的工艺 (1:50) 为了在不触发物理防篡改碎裂机制的前提下接触锁芯，LockPickingLawyer 在配备金属保护板的工作台上部署了注射器、微型手术刀、高精度镊子及倾斜固定锁身的磁性底座。他选用变性乙醇（denatured alcohol）作为溶剂，理由是该溶剂足以温和溶解压敏胶的粘附层，同时不会融化或扭曲全息薄膜本身。操作中，他先沿贴纸边缘注液软化胶质，用手术刀尖挑起微小边角，随后用镊子夹住贴纸并持续注入乙醇浸润接缝，以恒定拉力实现整张剥离。剥除后的完整贴纸被静置在一旁，待乙醇挥发后，受溶剂软化的胶水层能够重新恢复原有的物理粘性，为后续复原伪装提供了基础。跨过防撬蝴蝶盘的二号盘张紧开锁技术 (3:23) 解除钥匙孔遮挡后，LockPickingLawyer 开始对 Abus Plus 转片锁芯进行技术开启。针对位于一号盘位置、旨在干扰开锁工具张紧的防撬蝴蝶盘（butterfly disc），他放弃了常规的一号盘张紧方案，转而采用配备加长张紧凸耳的自制转片锁工具，直接跨过首层并在二号盘上施加张紧力。他解释道，该旁路技巧适用于二号盘切割深度为 0 号或 1 号的情况，涵盖了约三分之一（33%）的同类锁具；若遇到不兼容切位，则可退回常规方案。在成功张紧二号盘后，他先顺时针将所有转片全部归位，第一轮操作将各盘推入可感知的卡槽（无论真假门），第二轮则根据转动虚位排查深假门并将真门对齐，最终侧栏下沉促使锁芯旋转开启，整个开锁流程耗时远低于 3 分钟的预设上限。原标签复原粘合与干式撕裂的破坏性验证 (5:43) 挂锁成功开启后，LockPickingLawyer 进行了标签复原测试。由于背胶上的变性乙醇已充分挥发，他利用镊子将完好无损的全息贴纸重新贴回锁芯外侧，并在按压受力后确认其紧密粘附在金属外壳上，外观无任何撬动或拉伸变形痕迹。为证明该防篡改贴纸本身的物理防御属性并非伪劣产品，他在胶水干透的状态下尝试使用裸手徒手揭除。指甲刚扣起边缘施力，整张贴纸便立即发生不可逆的层裂与撕碎，在挂锁表面留下了锯齿状的明显篡改残留。该对照试验证实，防篡改贴纸在常规物理剥离下能正常发挥碎裂预警功能，但面对针对性溶剂的化学渗透时会出现防御盲区。该演示揭示了防篡改封条与机械锁芯在复合防护场景下的局限性：机械碎裂型标签易受到特定挥发性溶剂的化学脱胶旁路，而锁芯内部若仅在一号位设置防撬阻碍结构，亦可能被针对深层盘位的加长工具所绕过。

Good luck, Ben from Oakland.”）面对这份战书，LockPickingLawyer 回应称自己手上已经有至少一把同款锁，无论胜负都会把锁寄回，尤其是在看完接下来的操作后，对方恐怕也根本无法相信测试结果了。 ```mermaid flowchart TD accTitle: 防拆封条挑战与绕过流程 accDescr: 展示LockPickingLawyer从接收带封条的锁到无损移除、开锁及重新贴回的全过程 subgraph Prep ["挑战准备阶段"] A["奥克兰观众寄件 锁孔覆盖防拆封条"] --> B["配置工具与溶剂 变性乙醇 / 手术刀 / 镊子"] end subgraph Bypass ["无损拆除与开启"] B --> C["注射器注入溶剂 软化粘胶并完整剥离"] C --> D["等待溶剂挥发 恢复贴纸背胶粘性"] D --> E["二号盘长爪张拉开锁 绕过一号蝴蝶盘"] end subgraph Demo ["还原与破坏验证"] E --> F["将完整贴纸重新贴回开锁状态的锁体"] F --> G["徒手暴力撕下贴纸 触发全息防拆碎裂特征"] end ``` --- ### [01:50](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=110s) 使用变性乙醇无损剥离防拆贴纸 LockPickingLawyer 的作弊核心方案是：先完整剥离这张防拆证据贴纸，完成技术开启后，再将贴纸原样贴回。为了完成这项细致的手术级操作，他在桌面上放置了一块金属垫板，并准备了装有化学溶剂的注射器、一把精细小巧的手术刀、一把精密镊子，并在锁身底部吸附了一块磁铁，以便在操作过程中让镜头始终清晰地捕捉贴纸的动态。操作的第一步是将注射器内的溶剂精准滴在贴纸边缘。溶剂迅速渗透并软化胶水层，使手术刀的纤薄刀尖得以顺畅切入贴纸下方边缘。一旦刀片探入，他立刻使用溶剂浸润剥离面，随后用镊子替换下手术刀夹住贴纸边角。随着镊子轻柔向后牵引，注射器持续不断地向剥离结合面补充溶剂，确保贴纸不会受到拉扯应力而破损或触发防伪撕裂机制。LockPickingLawyer 透露，此处使用的溶剂正是变性乙醇（Denatured alcohol），他强调：“顺便说一句，溶剂是变性乙醇，对于这种贴纸完全没必要使用任何更具侵蚀性的溶剂。”（“By the way, the solvent is denatured alcohol, there's no need to use anything more aggressive for stickers like this.”）将贴纸完好无损地剥除后，他将其放置在一旁静置，等待表面的酒精自然挥发，以便背胶重新恢复粘性。 - 所需工具清单：医用注射器、变性乙醇（溶剂）、微型手术刀、高精度镊子、桌面金属垫板、底部固定磁铁。 - 防拆贴纸特性：若强行干撕会发生层间撕裂与碎裂，但在变性乙醇浸润下粘合剂会暂时失效，待溶剂蒸发后粘性即可恢复。 --- ### [03:23](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=203s) 创新二号盘张拉技术与极速开锁钥匙孔彻底暴露后，LockPickingLawyer 开始着手破解这把阿布斯（Abus）圆盘锁。常规操作首先是将锁芯内部的所有圆盘顺时针旋转至极限位置。但他并没有采用常规从一号盘施加张拉力（Tension）的传统方式，而是祭出了一套近期自主研发的全新开锁技术。他专门制作了一把带有超长张拉爪的圆盘开锁器（Disc pick），直接跳过位于一号槽位的“蝴蝶盘”（Butterfly disc），转而卡住二号盘施加张拉力。这项绕过技术具备很强的战术价值：在约三分之一的此类锁具中，只要二号位置的钥匙齿号为 0 号或 1 号切口，该方法就能绕开防拨保护并极其迅速地开启锁具；即便该锁不符合条件，他也随时能够切回传统方式。随着张拉爪精准锁定二号盘，他从工具端感受到了清晰的阻尼与反馈，这证实了该方案可行。随后，他操控拨针在盘片堆叠中逐一探索，先将各个圆盘推入缺口（Gate）——无论那是假缺口（False gate）还是真缺口（True gate）。完成初轮归位后，他从前至后依次比对辨别缺口真伪。他在盘片间穿梭摸索，逐一确认并微调三号盘及后续各盘，在连续排除数个假缺口并落入真缺口之后，锁芯瞬间转动解开。虽然中途并未开启秒表倒计时，但他非常自信开启时间绝对在 3 分钟以内，并打趣道：“不管怎样，本，这把锁你都能拿回去了。”（“Either way Ben, you're getting the lock back.”） --- ### [05:43](https://www.youtube.com/watch?v=xUJtqvYDnkg&t=343s) 复原封条与展示防伪破坏效果锁体被成功技术开启后，整场挑战中最具戏剧性的一幕上演了——将原本的防拆全息封条重新贴回。LockPickingLawyer 拾起放置在一旁风干的贴纸，确认表面残留的变性乙醇已经充分挥发，贴纸底部的粘胶已重新恢复黏性。他小心翼翼地将贴纸重新对齐锁孔位置按压抹平，贴纸与金属锁体表面贴合得严丝合缝，没有任何气泡或边缘翘起，外观上与从未被动过分毫的原装状态毫无二致。此时，锁具已处于开启状态，而防拆封条也看似完好地封在锁孔之上。为了向观众和本证明这枚贴纸本身确具防拆功能而非普通贴纸，LockPickingLawyer 决定当场进行徒手撕除测试。他用手指捏住贴纸边缘用力向外拉扯，在没有溶剂的保护下，贴纸瞬间分层碎裂，全息图层彻底破碎剥落，留下了清晰刺眼的破坏痕迹。他对此成效感到非常尽兴，总结道：“各位，这演出的精彩程度真是超乎我的预期，希望你们能像我一样乐在其中。”（“Okay folks, I could not have asked for this to play out any better, I hope you had as much fun as I did.”）在展示完被破坏的防伪特征后，他照例向观众致谢并结束了本期视频。 ## Mentioned LockPickingLawyer, 本（Ben from Oakland）, Abus（阿布斯）, Eminem, 《Stan》, Covert Instruments, 变性乙醇（Denatured alcohol）, 全息防拆标签（Tamper-evident sticker） ## Video description https://www.covertinstruments.com [Source](https://www.youtube.com/watch?v=xUJtqvYDnkg)

Original transcript

[0:00] this is the lockpicking lawyer and today [0:02] i'm going to cheat on a challenge mostly [0:05] because it's going to be a lot of fun [0:07] but also so i can show you something [0:09] i've never done on video before [0:12] but before i tell you how i'm going to [0:14] cheat let's take a look at the challenge [0:17] mr lock picking lawyer [0:19] thanks for taking the time to email with [0:21] me last week and i understand your issue [0:24] with accepting sealed packages [0:26] side note some gem of a human being [0:29] recently sent a tracking device to my po [0:32] box luckily i caught it in the post [0:34] office [0:35] it's really a shame that a creepy stan [0:38] points if you get that reference tried [0:40] to invade your privacy and ruin the fun [0:42] for the rest of us and yes of course i [0:44] get the m m reference [0:46] i decided to send you the lock anyway [0:48] but instead of wrapping the lock i put a [0:52] tamper sticker over the keyhole [0:54] and here you can see that holographic [0:57] sticker [0:59] we use these stickers at work to cover [1:02] assembly screws on hardware and they [1:04] break apart if someone tries to peel it [1:06] off i hope that works for you [1:09] as we discussed the time to beat is [1:11] three minutes about the time you took to [1:13] open the lock in video 1398 [1:17] if you beat it i'll send the keys if you [1:19] don't send the lock back to be honest i [1:23] hope you fail the lock was expensive and [1:25] i want to use it good luck ben from [1:29] oakland [1:30] then i already have at least one of [1:32] these so i'll send it back either way [1:35] especially because after this video i [1:37] doubt you'll trust the result anyway you [1:40] see we're going to remove the tamper [1:42] evidence sticker pick the lock and then [1:45] put it back on at least that's what i'm [1:47] going to try to do so let's get started [1:50] what we're going to need is a solvent in [1:53] a syringe that's why i have the metal [1:55] plate on my desk [1:57] a small scalpel [1:59] a pair of tweezers [2:01] and i'm also going to put a magnet on [2:04] the bottom of this [2:06] just so you can see the sticker as i am [2:08] working [2:10] so the first thing i'm going to do is [2:11] get a little bit of this solvent around [2:14] the edge of the sticker [2:18] that should loosen it up a bit so i can [2:20] get the scalpel underneath [2:37] okay it looks like we have the scalpel [2:39] in [2:40] i'm just dousing that area with the [2:42] solvent [2:45] now i'm going to replace the scalpel [2:47] with a pair of tweezers [2:50] and as i pull this back just keep [2:52] putting more of that solvent in [2:55] by the way the solvent is [2:57] denatured alcohol there's no need to use [3:00] anything [3:03] more aggressive for stickers like this [3:08] okay we got that off and [3:11] i'm going to set this sticker aside to [3:14] let that solvent evaporate [3:17] that way [3:18] the adhesive becomes tacky again and we [3:21] can put it back on [3:23] okay now we can start picking this [3:26] the first thing we do is rotate all of [3:28] those discs as far clockwise as they [3:30] will go and i'm actually going to use a [3:33] picking technique that i only recently [3:36] developed [3:37] i have a disc pick with super long [3:40] tensioning prongs to tension disc number [3:42] two we usually tension off of disc [3:44] number one in this case it bypasses the [3:48] butterfly disk in slot one and on [3:50] roughly one third of these locks if it [3:53] does work it'll open very very quickly [3:56] if it doesn't work i can just revert to [3:58] my normal picking method so let's get [4:00] this in [4:02] tension off of disk 2 and see if this is [4:04] one of those [4:06] locks on which it will work and that [4:09] means a number zero or one cut [4:12] in the number two possession [4:16] and i'm getting good feedback which is a [4:18] good sign [4:20] right now i'm going through the disc [4:21] stack just trying to get everything into [4:24] a gate not necessarily the true gate [4:29] and it seems like it's working nicely [4:33] let's go back to the beginning [4:36] that's in a gate [4:38] that's in a gate [4:44] there we go little click there [4:54] okay everything is in a gate now [4:57] i need to go through and differentiate [4:59] between false gates and true gates [5:01] that's definitely a false gate [5:05] okay i think we have that in a true gate [5:07] that's disc number three i believe [5:13] that was a true gate i think [5:17] definitely a false gate [5:20] another false gate [5:22] there's a true gate false gate [5:26] false gate [5:28] true gate [5:31] false gate and we got this open [5:35] i did not start a timer but i'm [5:37] relatively certain that was under three [5:39] minutes either way ben you're getting [5:41] the lock back [5:43] but [5:44] now that we have this open it seems [5:45] appropriate to put the anti-tamper seal [5:49] back on [5:55] and hopefully we gave this enough time [5:57] to dry [6:03] because after we get this back on i want [6:06] to try to peel the sticker off [6:08] so we can see the anti-tamper features [6:14] it seems like it's sticking all right [6:19] okay so now we have the anti-tamper [6:22] sticker in place and the lock is open [6:26] let's pull this off [6:35] and there you can see the anti-tamper [6:37] features that just comes right apart [6:40] okay folks i could not have asked for [6:43] this to play out any better i hope you [6:45] had as much fun as i did but that's all [6:47] i have for you today if you do have any [6:49] questions or comments about this please [6:51] put them below if you like this video [6:53] and would like to see more like it [6:55] please subscribe and as always have a [6:58] nice day thank you
