12976000/0106 large old style remote (zippo ligher style, no key ring
14076003/0706 smaller newer style ( smaller with key chain attachment)
Both work on my 92 500 sel. The programming proceedure is in the owners manual " Point at the door sensor, push button, and unlock door with a key" If you dont see a flashing red light in the window after holding the buttton for a few seconds the remote or battery is bad. You will have to go from there yourself, if your service rep cant get them to work maybe they are not for your car.
These older versions were infrared and picked up in the door handles and trunk sensor, the newer were picked up in the rear view mirror.
