Transponder Keys

What is a transponder key?
A transponder key is a specialized car key equipped with a microchip that enhances vehicle security. These advanced keys gained popularity among auto manufacturers in the mid-1990s and are now a standard feature in almost all vehicles as a theft deterrent.

How do transponder keys work?
Transponder keys function in tandem with a vehicle’s immobilizer system, which is integrated into the car’s ignition. Each transponder key is uniquely programmed to correspond with the vehicle’s engine control unit. When the key is inserted into the ignition, the chip communicates with the immobilizer, allowing the car to start only if the correct key is used. If the key is not correctly cut or lacks the proper programming, the vehicle’s engine will not start.

Does my vehicle require a transponder key?
If your car was manufactured in the last two decades, it likely requires a transponder key. Most modern vehicles are equipped with keyless entry systems that include a transponder key as a key component of the vehicle’s built-in security features. While some key cutting services may offer transponder key duplication, many car owners typically need to visit a dealership for transponder key replacement.
