Updated February 21, 2017

Transponder keys are a popular feature on various cars around the world, and they can be electronically synced to your engine to start your car. Also known as chip keys or engine keys, they embody a technology that makes it the only way to start your car with a key once programmed. Programming can be completed easily in a few minutes with no professional experience, allowing you to use your keys without taking them to the dealership.

Insert your transponder key into the car's ignition and turn the key to the "On" position. Leave the key there for 10 minutes and 30 seconds.

Turn the key to the "Off" position within 45 seconds and then back to the "On" position for another 10 minutes and 30 seconds.

Cycle it back off within 45 seconds again and then to the "On" position for one last turn of 10 minutes and 30 seconds.

Turn the key back to the "Off" position, cycle it back to "On" and the programming will be completed.
