Key Fob Replacement

Key fob replacement starts from $150. Locksmith Auto replaces and programs remote key fobs, smart keys, and push-to-start proximity keys for all major vehicle brands. Same day mobile service. We come to you with the fob and programming equipment.

Your fob isn't just a remote. It's got a transponder chip for the engine immobilizer, a remote transmitter for keyless entry, and on newer vehicles a proximity sensor for push-to-start ignition. Lose the fob and you lose access to all three systems at once.

Four common fob types. Standard remote fobs run $150-200. Smart proximity keys cost $200-320. Remote head keys with a built-in blade are $150-250. Flip/switchblade keys fall between $150-230. The price gap comes from chip complexity and how many functions are programmed into the fob. Push-to-start smart keys cost more because they talk back and forth with the vehicle constantly.

Replacement takes 15-45 minutes. We cut the emergency blade if there is one, program the remote functions (lock, unlock, trunk, panic), sync the transponder chip with the immobilizer, and test every button. Locksmith Auto checks signal strength at multiple distances before we call the job done.

Compare our pricing to the dealer. BMW charges $400-600 for a single smart key. Toyota asks $250-350. Locksmith Auto provides the same OEM-compatible fob, programmed with the same protocols, for $150-320. Same range, same functions, same security level. The fob doesn't know the difference.

Battery life on most key fobs is 2-4 years. When the battery gets low, you will notice reduced range, intermittent response, or the push-to-start requiring you to hold the fob against the start button. Replacing the battery costs $5-10 and takes 2 minutes. If the fob still malfunctions after a fresh battery, the internal circuit board may be damaged and full replacement is the fix.
