Keyless Entry Transmitter: Testing and Inspection

1. Replace the remote keyless entry transmitter batteries as described. Test each of the transmitter functions. If OK, discard the faulty batteries. If not OK, go to Step 2.
2. Perform the Remote Keyless Entry Transmitter Programming procedure with the suspect transmitter and another known good transmitter, as described.
3. Test each of the remote keyless entry system functions with both transmitters. If both transmitters fail to operate the power lock system, see the diagnosis for the Power Lock and Remote Keyless Entry Module. If the known good transmitter operates the power locks and the suspect transmitter does not, replace the faulty transmitter.

NOTE: Be certain to perform the Remote Keyless Entry Transmitter Programming procedure again following this test. This procedure will erase the access code of the test transmitter from the power lock and remote keyless entry module.
