Introduced in the mid-1990s as a response to increasing car theft, transponders use Radio Frequency Identification (RFID) to communicate with the vehicle's Engine Control Unit (ECU).

When a key is inserted into the ignition or brought within proximity of a push-to-start button, the car sends a signal to the transponder chip inside the key. If the special code stored in the key matches the code programmed into the car's immobilizer, the engine is permitted to start. If the codes do not match, the fuel system is disabled, and the car remains fixed.

There are a number of circumstances where a UK motorist might discover themselves in requirement of expert reprogramming services.
Lost or Stolen Keys: When a key is lost, it isn't enough to just cut a brand-new blade. The vehicle must be configured to recognize the brand-new transponder.
