This is about a set of keys where the transponder key is OEM, made by authorized distributor in the US and is a genuine GM part.

The set is about 1 uncut OEM transponder key with the chip ready to be programmed inside the plastic head and the GM emblem on the front, and a second dummy regular metal head key with no logo as a gift just to open doors and trunk in case of lockout. You'll save money and time if you keep the dummy key in your wallet and no need to call a locksmith to open up your car.

The term transponder (short-for Transmitter-responder)means an automatic device that transmits a predetermined message in response to a predefined received signal.

These car year, make and models have keys with transponders hidden inside the plastic head of the key. 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. Transponder keys have no battery; they are energized by the radio signal itself.

When you attempt to start the vehicle, the on board computer sends out a signal that is picked up by the transponder in the key. The transponder then returns a unique signal to the vehicle's computer, giving it the OK for the vehicle to start and continue to run. This all happens in less than a second, and is completely transparent to the vehicle operator. It is a very effective system that does its job without the vehicle owner having to think about it, or modify his / her usual routine.

This system was introduced to help reduce vehicle crime. If the transponder key is missing or faulty the car will not start.
