Component Tests and General Diagnostics

1. Replace the Remote Keyless Entry (RKE) transmitter batteries. See Remote Keyless Entry Transmitter Battery Replacement for the procedures. 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. Use a DRB scan tool, as described in the proper Diagnostic Procedures.
3. Test the RKE system operation with both transmitters. If both transmitters fail to operate the power lock system, see the diagnosis for the Remote Keyless Entry Receiver. 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 RKE receiver.
