What's involved

What this repair actually is.

Modern keys carry a security chip that must be electronically paired to your car's immobilizer before the engine will start. We supply or program the key, sync it with the anti-theft module, and verify remote functions like lock and unlock work — often at a significant saving over the dealer.

Symptoms

How you can tell.

  • Lost or broken key or key fob
  • Only one working key left and you want a spare
  • Security or key warning light stays on
  • Engine cranks but immediately shuts off (immobilizer lockout)
  • Remote buttons stopped working after a battery change
If you delay

Waiting until your last key is lost turns a routine spare-key visit into a costlier all-keys-lost procedure, often with a tow.
