How to Program a Cadillac Keyless Entry Remote
- 1). Insert the key in the ignition. Turn the key to “Run” and immediately back to “Off”.
- 2). Open the interior fuse panel cover and pull the fuse for the radio. Grasp the fuse with the fuse pullers found inside the fuse panel and pull it straight back to remove it. The fuse location can vary based on your specific vehicle, so check the fuse map inside the panel cover to verify which fuse belongs to the radio circuit.
- 3). Toggle the ignition key from “Off” to “Run” and back, three times in rapid succession. The doors will lock and unlock to indicate that you activated programming mode.
- 4). Press the “Lock” and “Unlock” buttons simultaneously and hold them for at least 15 seconds or until the door locks cycle. Repeat this step for every keyless remote you need to program.
- 5). Replace the radio fuse by pushing it straight into the empty slot in the fuse panel. Replace the fuse panel cover.
