A TRANSPONDER IN YOUR IGNITION KEY?

The majority of car keys built after 1995 contain transponder chips hidden inside the plastic head of the key. The purpose of a transponder chip is to disarm a vehicle immobilizer when the car key is used to start the engine.
The owner of the car may not even be aware that the transponder is there because there are no buttons to press. When a key is inserted into the ignition lock cylinder and turned, the car's computer sends a radio signal to the transponder. Unless the transponder replies with a valid code, the computer will not allow the engine to be started.
