How to Replace a Transponder Key

160

Transponder keys have become a popular technology on cars all around the world. These keys are used to electronically sync to your engine, and once programmed, only a transponder key can be used to start your car. You can replace a lost or disabled transponder key yourself in just a few minutes by reprogramming it. The programming sequence is completed from the driver’s seat and will have your remote ready to use right away.

Step 1

Acquire a new cut key from the dealership or from the installer of your transponder transmitter system and have two previously programmed keys ready.

Step 2

Insert the first programmed key into your car’s ignition and turn it to the “On” position.
