Help - 02 suburban keyless entry

[Uncle Jed]

I would appreciate any suggestions anyone might have. Keyless entry (both FOBs)quit working about 3 months ago. Replaced the batteries - attempted to reprogram - changed the fuse - still nothing. When attempting to reprogram held lock and unlock buttons down but got no response (no cycling of locks, etc). Anyone have any ideas? Where on the vehicle does it receive the signal from the remote? That is the only place I can think to check but don't know where it is. Once again, any help would be appreciated.

Holding down the LOCK and UNLOCK buttons on each remote for 7 seconds after changing the batteries should sync them back to the vehicle.

If that doesn't work, here is the 02+ programming procedure:

All transmitters which are to be recognized by the PDM must be programmed in a single programming sequence. When using this program method, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter.

The order in which the transmitters are programmed will determine its numbering position within the PDM memory. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number stamped on the transmitter case is for reference only: #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available.


1. Close all the vehicle doors.
2. Insert the ignition key into the ignition lock cylinder.
3. Press and hold the door unlock switch.
4. While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
5. Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
7. Repeat the previous step to program up to four transmitters.
8. Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
9. Operate the transmitter functions in order to verify correct system operation.
