Build and Kill Zombies Codes (Active and Expired)
Build and Kill Zombies codes come and go with each hacker or boss event, so I line this list up against Dexerto and Pocket Tactics before every update. As of today five codes are confirmed working, with ZEUS the most recent addition.
Build and Kill Zombies codes are the short strings the Zombie Car Crusher team posts for community milestones and events, redeemed from the codes box at the bottom of the Shop for free cash, lightning tokens, hacker tokens, and bolt-on parts like engines, fuel tanks, and passenger seats. the whole loop is build a vehicle, drive it as far through the horde as you can, then spend what you earned on a better build. Cash buys the parts, the free engine and tank from COMMUNITY are a real head start, and the two passenger seats from MOREFRIENDS let friends ride along without you grinding for them. Lightning tokens feed the event shop while it lasts.
Quick tip.redeem COMMUNITY and CashDrop the moment you finish the tutorial, then bolt the free engine onto your first car before you spend a single coin. IAMPRO is the odd one out, it only unlocks after you set a best distance record, so push one decent run first and come back for it.
Active Build and Kill Zombies codes 11
All five were listed as working by Dexerto on October 5 and by Pocket Tactics a week earlier. One aggregator still shows the September event codes as live, but two sources say they are gone, so they sit in the expired list until someone proves otherwise.
| Code | Reward | Copy |
|---|---|---|
| FORGE New Expires soon | 50 crypt tokens | |
| DOCTORSORDERS Expires soon | 250 crypt tokens | |
| TRUSTTHEJUICE Expires soon | 100 crypt tokens and 10 minutes of 4x luck | |
| HOLLOW Expires soon | 50 crypt tokens | |
| HOLLOWKING Expires soon | 100 crypt tokens and 10 minutes of double luck | |
| CRYPTCRAWLER Expires soon | 250 crypt tokens | |
| ZEUS Expires soon | 50 lightning tokens | |
| IAMPRO Expires soon | 5k cash (requires 1k studs) | |
| COMMUNITY Expires soon | 1k cash, one small engine, one small tank | |
| CashDrop Expires soon | 500 cash | |
| MOREFRIENDS Expires soon | Two passenger seats |
If a code comes back invalid, check capitalization first, then whether you already claimed it. IAMPRO failing almost always means you have not set a distance record yet.
Expired Build and Kill Zombies codes
These were tied to the hacker event, the sci-fi week, and the boss reveal in September. Event codes in this game shut off the day the event does.

New Build and Kill Zombies codes land with events, new bosses, and community milestones, and the developers post them on Discord and the Roblox group page first. The hacker and sci-fi event codes from last month are already gone, which tells you how fast event ones turn over.Codes are case sensitive, one use per account, and the Shop only appears once the tutorial is done. Event codes expire when the event ends.
- Redeem in game: finish the tutorial, open the Shop on the left, scroll to the codes box at the bottom.
- Rewards: cash, lightning tokens, and free parts (engine, tank, passenger seats).
- IAMPRO needs a best distance record first; sources quote 1,000 to 1,500 studs.
- Codes are case sensitive, so CashDrop has to be typed exactly like that.
- Event codes (hacker, sci-fi, boss weeks) die when the event ends.
How to redeem Build and Kill Zombies codes
Everything happens inside the Shop. There is no website, and the box only shows up after the tutorial.
- Launch Build and Kill Zombies on Roblox and complete the short tutorial.
- Open the Shop from the left side of the screen.
- Scroll to the very bottom to find the codes box.
- Type or paste a code exactly as written, capitals included.
- Press Redeem. Cash and tokens land instantly, parts go to your inventory.
Can't see the Shop? You are still in the tutorial. Finish it, head back to the lobby, and the button appears on the left.
Build and Kill Zombies codes FAQ
What do Build and Kill Zombies codes give you?
Mostly cash, which buys vehicle parts, plus lightning tokens for the current event shop. COMMUNITY also drops a small engine and a small tank, and MOREFRIENDS adds two passenger seats, which are the parts you would otherwise grind for first.
Why won't IAMPRO redeem?
It is gated behind a best distance record. Trackers disagree on the exact number, somewhere between 1,000 and 1,500 studs, so drive one solid run through the horde before you try it again.
Are the codes case sensitive?
Yes. CashDrop with a capital C and D is the usual one people trip over. Copy from this page rather than typing and you will not have the problem.
Are the hacker event codes still working?
Not according to Dexerto and Pocket Tactics, which both list HACKER, 1x1x1x1, and the rest of that batch as expired. One site still shows them live, but with two sources against, I keep them in the expired section.
How often do new codes drop?
Roughly once an event: a new boss, a themed week, or a community milestone. September had several, so the pace is healthy, but each one tends to last only as long as its event.
Where are new Build and Kill Zombies codes posted first?
The official Discord and the Zombie Car Crusher group page on Roblox. Dexerto, Pocket Tactics, and RobloxDen mirror them within a day, which is what I cross-check before adding anything here.
