**Title:** Cracking Combination Locks (Informal Lock-Picking Experiment)
**Summary:**
* The author, with prior experience in picking standard locks, attempts to crack a combination lock for the first time.
* They disassemble a cheap combination lock to understand its mechanics and discover it can be exploited by applying tension to the shackle and finding the "gate" on each wheel.
* Using this technique, they successfully crack two combination locks:
1. A newly purchased Master lock with a known combination (verified their method works).
2. A lock on some chained-up bikes with an unknown combination.
* A second technique, feeling for shackle movement or dial looseness while applying tension, is also effective.
* The author briefly mentions applying a similar technique to crack a door combination lock, highlighting the vulnerability of such locks.
* The video concludes with a disclaimer, encouraging viewers to only experiment with their own locks and emphasizing that stealing is illegal.
Here are the key facts extracted from the text, numbered and in short sentences, excluding opinions:
**Lock Picking Experience and Background**
1. The author learned to pick a standard key lock 3.5 years ago.
2. It took the author 47 minutes to open their garage door lock using a lock-picking kit.
**Combination Lock Details**
3. The author purchased a Master combination lock from Amazon for around £20.
4. The lock's combination can be set using a provided key.
5. The initial combination was 8-4-B-5, as indicated on the lock's packaging.
**Lock Mechanics**
6. The combination lock has 4 wheels with number markers.
7. Each wheel has a notch (gate) that must align with teeth on the shackle to unlock.
8. The lock's shackle must move upwards to unlock.
**Decoding Process**
9. The author's method involved applying tension to the shackle and finding the correct wheel alignment.
10. The author initially tried decoding by checking each number on the first dial until the second dial started binding.
**Specific Lock Decoding Results**
11. The author successfully decoded the first lock using the above method, discovering the combination was 1-1-3-? (last digit not specified in this section).
12. The author then set a new combination and decoded it again, paying $6.99 for a second lock, with the same ease.
13. The combination for the bike lock was different and required a slight variation in the decoding technique.
**Additional Experiments**
14. The author built a wooden safe to test decoding a door combination lock.
15. The door combination lock was cracked in approximately 2 minutes using a similar tension-and-button-pushing technique.
**Miscellaneous**
16. The author emphasizes that stealing is illegal and encourages viewers to only attempt lock picking on their own property.
