I have a 91 Deville with factory key less. Have no remotes. I ordered what was said to be compatible remotes off of Ebay. To program you ground the G pin in data link connector. That worked fine and remote programmed fine. It unlocks door with one hit. Unlocks all doors on 2nd hit. And pops trunk with trunk button. BUT IT FAILS TO CANCEL SECURITY ALARM. so when you open door horn goes off. You have to put key in door and unlock to cancel alarm. Is there a chance remote is wrong and takes a different one and that's why security don't cancel. Or is there another issue?
