If you have RPO code AU0 in your glove box then you are equipped for keyless entry. Simply purchase new fobs and follow the programming procedure.

Please watch our installation videos which are shown above.

Up to four (4) fobs can be programmed at once.

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&feature=youtu.be
