How to Program a Keyless Entry for a 2003 Chevy Suburban
- 1). Gather your car key and the keyless-entry remote you want to program to the Suburban. Only a factory-replacement remote will synchronize with the system.
- 2). Verify that all of the doors are closed, including the rear-hatch door. Open the driver's door, take a seat and close the door.
- 3). Place the key in the ignition, but do not turn it. Press and hold the "Unlock" switch on your door's master-control panel.
- 4). Turn the ignition in the following sequence: on, off, on, off. When turning the key to "On," do not start the engine. Perform this rapidly for success.
- 5). Release the "Unlock" switch. You'll hear the doors lock. If you don't, start the procedure over.
- 6). Simultaneously press "Lock" and "Unlock" on the keyless-entry remote. Hold these buttons down for about 30 seconds. You'll hear the door locks cycle again. This lets you know the remote is programmed. Turn the ignition to "On," then "Off" to finish.
