92 park avenue security door locks

My 92 park avenue has the security system, the keychain remote does nothing. This has always worked before just quit on day. I have two remotes and neither will work, I have changed the batteries in the remotes and checked all the fuses on the car and can find nothing?? please help.
Please send any suggestions to markabner@yahoo.com
thanks.

Jump the (ALDL) Assembly Line Diagnostic Link. You will find this connector under the driver side dash, but you will have to look through a square cut out in the panel to see the connector, it is recessed behind that panel, almost directly under the steering column.

Jumper pin A to pin G with a fused jumper (3A)
Doors will lock and unlock
Press the UNLOCK button on the remote
Doors should lock and unlock again
if you have more remotes press their unlock button (up to 4)
remove jumper wire
