Keyless Entry Transmitter Fobs

[PSReattaFan]

I have come upon many keyless entry fobs that look just like the 1991 Reatta fob, except for the front mfr logo.  These have a multitude of FCC and part numbers.  My original Reatta fob is P/N 22093186 and FCC GLQ926-1507.  But there are Cadillac and Olds fobs P/N 22110687, 22100945, 10178734, 22094436, 22110689, 22100649 and an FCC ABO0502T.

 

My question:  Are these fobs interchangeable?  Will they all work on the Reatta if programmed using the trunk programming wire? When replacing or adding a second remote fob, which ones are compatible with the Reatta? (1991 Black/Tan and 1989 White/Maroon).

 

Thanks!

There was a place in Florida that sold generic remotes ..... "remotes are us"  but they do not come up on  a search, 

however here is one that sells originals...........  https://www.keylessentryremotefob.com/shop-by-car-make/buick/

Yes, the cadillac one that looks like the Reatta fob will work.

Just program it like it was for the Reatta.
