Keyless Entry Transmitter: Testing and Inspection
Perform the following check to diagnose all transmitter operations.
1. Move the vehicle outside and as far away from metal objects as possible. The remote keyless entry system may not operate if there are metal
objects between the transmitter and the vehicle.
2. Turn the ignition "OFF," lower the windows, and close the doors.
3. Stand at the rear bumper, aim the transmitter at the vehicle and operate all functions on both transmitters (if available).
^
If a single function on one transmitter is inoperative, replace that transmitter.
^
If all functions on one or both transmitters are inoperative, reprogram both transmitters and repeat diagnosis.
If one transmitter will not program, replace the battery in that transmitter.
^
If the transmitter does not operate after replacing the battery and reprogramming, replace the transmitter.
4. If all functions on both transmitters operate, stand 5 feet from the vehicle at several points around the vehicle and check operation of both
transmitters at each point.
^
If one transmitter does not operate at some points where the other transmitter does operate, replace the battery of the transmitter that does not
operate.
^
If both transmitters operate 5 feet from the vehicle, the system is operating properly and no repairs should be attempted.
