Hi to all and any help would be great. I just stepped up from a (90) 760 GLE Turbo Sedan to a (96) 850 GLT Sedan and have a couple of questions about the the factory alarm system. I purchased the car last week with 70000 miles on it from an elderly lady so it is well taken care of, but she lost the remotes and now I am wondering which ones to get to work with the system. The car does have the alarm system on it as verified by the red light on the dash and comes on when the door is locked with the key and alarm sounds when a door is opened with starter kill. I was told that their several out there and you can get the wrong one with the incorrect FCC number which will not work with your car. Is there a way to find out which one I need since the dealer wants an arm and a leg just to give you that info? Is there a brain somewhere with the correct FCC number attached that would make selecting simple and where would I find it? I have seen some on Ebay, they look the same (just a lock and unlock button) just with different FCC numbers like CWT5653T, CWTTFWBIG and I can't find the other one I saw. Nevertheless, I can only remember seeing 3 different FCC numbers and just need to know which one will work with my 96 model. Any help would be great

 

There is only 2 styles for the 850 and they shouldn't charge you anything to tell you which one you will need.
