1998 Saturn SL1

Before u start programing remotes I would take them apart and clean them they get black powder that causes the buttons to become inop. Clean both the circuit board contacts and the button contacts u can use a tissue. Also check the battery it should be around 3 volts. If it still doesn't work then look at the obd2 connector where u hook a scanner to to get codes. Top row of pins from left to right jump pin 4 to pin 8 u will hear a short horn honk now it's in learn mode leave the jumper the entire time ur programing don't take it out till ur done programing. Once u do this the rke module forgets all remotes so u will have to reprogram all working remotes at this time. Now hold lock and unlock buttons down at the same time till u hear another short honk and the locks on the car will cycle. Then move on to the next remote till there all programed. Try cleaning them and checking the batteries first u may not have to program them. Let me know how it goes.
