Transponder Key Programming

If your engine won’t crank or the security light keeps flashing, the transponder could be the culprit. Miami Key Master programs new chips and syncs them with your car’s immobilizer on the spot.

Secure Starts Every Time

Transponder keys carry tiny RFID chips that send an authorization code to the vehicle’s computer. When the chip malfunctions or a new key is added, proper syncing is essential. Our locksmiths connect dealer-level diagnostic tools to your OBD port, clear outdated codes, and program fresh transponders that communicate flawlessly with the ECU. We verify start-up, remote functions, and anti-theft indicators before leaving, restoring full security and convenience in one visit.

FAQ's

What’s the difference between cutting and programming a key?

Cutting shapes the metal blade; programming syncs the embedded chip with the engine’s immobilizer so the car will start

Yes, we can remove its code from the ECU memory so the missing key will no longer start the vehicle

Typical sessions run 10-20 minutes once we access the OBD port and security code

Absolutely—our equipment covers both classic transponders and newer proximity systems

No. Key batteries power remote functions, not the transponder chip, so programming remains intact
