My keyless entry quit working. I checked the batteries in the fob they are both ok. Any other checks I could do?

 

From the '98 manual:

"REMOTE KEYLESS ENTRY TRANSMITTER
(1) Replace the Remote Keyless Entry (RKE)
transmitter batteries. See Remote Keyless Entry
Transmitter Battery Replacement in the Service Procedures
section of this group. Test each of the transmitter
functions. If OK, discard the faulty batteries.
If not OK, go to Step 2.
(2) Program the suspect RKE transmitter and
another known good transmitter into the RKE module.
Use a DRB scan tool, as described in the proper
Diagnostic Procedures manual. See Remote Keyless
Entry Transmitter Programming in the Service Procedures
section of this group.
(3) Test the RKE system operation with both
transmitters. If both transmitters fail to operate the
power lock system, use a DRB scan tool and the
proper Diagnostic Procedures manual for further
diagnosis of the RKE system. 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."

 

I have an early 98, is it possible I have keyless?
