The transponder key is an aftermarket option that can be programmed for a number of vehicles. Also known as a chip key or ignition key, this key offers a level of convenience and security for your car. If your car is equipped with a chip key system, only a programmed key can turn on the ignition in your vehicle. Programming or reprogramming of your chip keys can be done in just minutes from your vehicle using just the key itself.
Insert your chip key into the ignition of your vehicle and turn the key to the "On" position.
Leave the key in the "On" position for 10 minutes and 30 seconds, then turn it back to the "Off" position.
Repeat Steps 1 and 2 two more times, leaving the key in the "On" position for 10 minutes and 30 seconds a total of three times. Turn the key to the "Off" position after the third time.
Turn the key back to the "On" position to complete the programming sequence. You can now use the newly programmed key to start your car.
