The year ranges are only provided as a guide, we always recommend checking the FCC ID on your original fob and comparing it to the ones we have listed.

You can find the FCC ID on the back of your original fob. If you don't have an original fob, please contact your local dealer and provide them with your VIN. They will provide you with the OEM part number and we will be able to provide you with the correct key fob based on that part number.

Yes, you can mix the old style with the new style.

Keyless entry refers to the ability to enter the vehicle without the need to turn the physical key onto the vehicle’s door lock. Keyless entry allows users to enter the vehicle with the use of a key fob.

Vehicles that are equipped with this feature will be compatible to program our key fobs.

The RPO code is printed on the sticker in the passenger glove box. It is the left sticker in the glove box.

Our fobs generally don't work with aftermarket remote start systems.

The only exception to this, is some systems utilize a triple click of the OEM fob to remote start the vehicle. If you have a system that uses the OEM fob to trigger the remote start (like the one previously mentioned), our fob will also work but you must purchase the one without remote start (you will just triple-click the same button sequence as OEM).

The fobs come with a battery pre-installed. If you find yourself needing to replace the battery at a later point in time, you can reference this video: https://www.youtube.com/watch?v=pYv2N_RYd_g
