Erasing Transmitter Codes
WARNING: This page is about a different car, the 2003 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
To erase the universal transmitter codes, simply hold down buttons 1 and 3 until the two green dots below the house symbol begin to flash.
NOTE:
Individual channels cannot be erased. Erasing the transmitter codes will erase ALL programmed codes.
