Locks and Security Note: Replacement of the battery will not cause the IKT to become deprogrammed from your vehicle. The IKT should operate normally after battery replacement. Replacing lost integrated keyhead transmitters (IKTs) If you would like to have your integrated keyhead transmitters reprogrammed because you lost one, or would like to buy additional IKTs, you can either reprogram them yourself, or take all IKTs to your authorized dealer for reprogramming.

Note: At least two IKTs are required to perform this procedure yourself.
