Code Raiding: How Code Locks Actually Work (and the Codes People Actually Use)

A code lock has 10,000 possible combinations, and the game punishes wrong guesses. On paper that makes guessing pointless.

In practice, codes are picked by humans. People set codes they can remember while getting shot at: repeated digits, keypad patterns, birth years, memes. That means the real search space isn't 10,000 equally likely codes — it's a short head of very popular codes and a long tail nobody uses. If you guess in popularity order instead of randomly, the odds change dramatically.

Code raiding won't open every door. But against a random base, it opens a lot more of them than you'd expect — silently, with zero boom cost.

Before you burn tries, know exactly what the lock does back:

• Wrong guess = electric shock. Damage starts at 5 and escalates by 5 with each rapid failed attempt; the escalation resets after about 10 seconds. Pace your guesses and the damage stays trivial — bring a bandage anyway.
  
• 8 failed attempts = 15-minute lockout. After eight wrong guesses you personally cannot try that lock again for 15 minutes.
  
• The lockout is per PLAYER, not per lock. This is the single most important fact in this guide. When you're locked out, your teammate isn't. A group rotating through the same door multiplies the guess rate.

The math per person: 8 tries per 15 minutes is 32 guesses an hour. Solo, that's slow. A five-man rotating on one door is 160 guesses an hour — and with a popularity-ordered list, that's often enough to crack a door in a single play session.

This top 25 comes from a dataset of nearly a million real 4-digit codes, popularity-ordered:

 1. 1234      6. 1004     11. 9999     16. 1313     21. 0909
 2. 1111      7. 2000     12. 3333     17. 8888     22. 2580
 3. 0000      8. 4444     13. 5555     18. 2001     23. 0007
 4. 1212      9. 2222     14. 6666     19. 4321     24. 1818
 5. 7777     10. 6969     15. 1122     20. 1010     25. 1230

The patterns behind the list, so you can improvise past it:

• Repeats and near-repeats — 1111, 4444, 1212, 1122, 1010. Fastest thing to punch in mid-raid.
  
• Keypad walks — 2580 is the middle column of a phone keypad, top to bottom. 1234 and 4321 are the obvious walks.
  
• Years — 2000, 2001, 1984–1999. If you know roughly how old the base owner sounds on voice, you know what decade to try.
  
• Memes and culture — 6969, 0007, 1337. 1004 is up at #6 because it sounds like "angel" in Korean — proof that these lists are global.

The failure mode of group code raiding is two people unknowingly guessing the same codes. Every duplicated guess is a wasted lockout slot.
The manual fix: assign ranges out loud. "I take the repeats and patterns, you take 1990–2010, you take the top-25 list." It works, but it falls apart as people die, relog, or forget where they were.
The lazier fix: I built a free tool for exactly this — https://code-raid.com. One person creates a raid and shares a link; everyone who opens it gets dealt their own personal block of codes in popularity order, guaranteed no overlap, with live progress for the whole squad. When someone cracks it, everyone's screen shows the code. No signup, works on phones, full disclosure: it's my project.
Either way — manual or tool — the principles are the same:

• Guess in popularity order, not randomly.
  
• Never duplicate a guess across the squad.
  
• Rotate players as lockouts hit; the door never gets a break.
  
• Post someone on overwatch. You're standing still at a door for minutes at a time.

Reading this as a base owner? Everything above works against you too. The counterplay is cheap:

• Never use anything resembling the list above — no repeats, no keypad patterns, no years, no meme numbers.
  
• Genuinely random 4 digits (roll them, don't "think of" them) puts you in the long tail where guessing is hopeless.
  
• Use different codes on different doors, and change them if you've given one out to a since-departed teammate.
  
• A shotgun trap behind the door turns a 15-minute lockout camp into a very bad trade.

Guessing codes is a legitimate vanilla mechanic on official servers — no exploits, no glitches involved. Some community and modded servers restrict or ban code raiding in their own rules, so check the server's rules before you spend an hour on someone's door.

Good luck. May all their codes be 1234.
