(314) 728-5700When to Call Doorbusters for a New Car Key
Three of the most common reasons St. Louis drivers call us for replacement keys.
Lost All Your Keys
No working key at all? We make one from scratch. Your VIN gives us the factory cutting code, we cut the key on-site, and program the chip to your car. No tow truck, no dealer wait list.
Broken or Worn Key
Key snapped in the door, stuck in the ignition, or so worn it barely turns? We extract broken pieces, cut a fresh key to factory specs, and get you back on the road the same day.
Down to One Key
One working key is one bad day away from an emergency. Adding a spare now takes minutes and costs far less stress than an all-keys-lost situation later. We cut and program it at your driveway.
Every Type of Car Key We Replace
From basic metal keys to push-button smart keys, our mobile units cut and program them all on-site.
Traditional Metal Keys
Basic double-edged keys for older vehicles, cut by code to factory specifications in minutes.
Transponder Keys
Chip keys used in most vehicles since the late 1990s. We cut the blade and program the chip to your immobilizer.
Laser-Cut Keys
High-security sidewinder keys with a milled groove, common on European and newer domestic models.
Smart Keys & Fobs
Proximity keys for push-button start vehicles, programmed on-site including all-keys-lost situations.

How Our Car Key Replacement Works
From your first call to driving away with a working key. Here is what happens next.
GPS Dispatch
under 2 minCall (314) 728-5700 with your vehicle year, make, and model. Our dispatcher confirms the key type and routes the closest mobile unit with the right blank on board.
Ownership Verification
2-3 minYour technician checks photo ID and proof of ownership (registration, title, or insurance card). It protects you: nobody should be able to get a key to your car but you.
Key Cut On-Site
10-20 minUsing your VIN, we pull the factory cutting code and cut the new key in the van with precision equipment. No original key needed. Broken key stuck in the lock? We handle broken key extraction first.
Programming & Testing
10-30 minThe transponder chip or smart key is programmed through the OBD-II port, then tested in the doors, trunk, and ignition. Need remote buttons too? Key fob programming happens in the same visit. If the ignition itself is worn, we also do ignition repair.

- On-site key cutting by VIN code, no original needed
- Transponder chip and smart key programming
- All-keys-lost replacement with no tow required
- Traditional, laser-cut, and high-security keys
