System Operation Check

Perform the following check to diagnose all transmitter operations, using two transmitters (if available).

1. Move 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. Lower all windows, turn ignition OFF, and close all doors.
3. Stand at rear bumper, aim transmitter at vehicle, and operate all functions on both transmitters (if available).
   • If a single function in one transmitter is inoperative, replace that transmitter.
   • If all functions on one or both transmitters are inoperative, reprogram both transmitters and repeat diagnosis. See PROGRAMMING  . If one transmitter will not reprogram, replace the battery in that transmitter.
4. If all functions in both transmitter operate, stand five feet away from the vehicle at several points around the vehicle and check 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 five feet from the vehicle, the system is operating properly and no repairs should be attempted.
