Im not sure if my 94 bonneville SSEI came with keyless entry. If It did the original owner lost it. Is there any way I can get it replaced?

99.999999% you have keyless entry

you will need a remote that has the last 4 letters ofthe FCC ID to be 302T OR 303T

Where can I find one?

Either Billbost37 (A member on this site) to see if he has one, if not him, Ebay

Boost is out of remotes at the moment. Ebay is probably the best bet.... or post in Wanted..another member may have some.

So will this one work then?

eBay Motors: BUICK 91-95 Riveria Keyless Entry Remote (302T) (item 260187984870 end time Dec-22-08 17:09:07 PST)

More likely, this one eBay Motors: Pontiac Bonneville Keyless Entry Remote 25678792 (item 380086631033 end time Dec-11-08 18:32:14 PST)

Contact the seller, they have a ton of them. Tell them your year/model and they will fix you up.

Please add your year and trim level in your signature please, it will help you get better help here on the Forum, Thanx

I contacted that seller and got this reply.

Remote (fcc/part#) req'd defined only by transceiver installed which may overlap/differ for same year/model ( hence advertised as .....' type ' ...remote as then there may obviously then be more than 1 type available for same year/model,..... and buyers directed to check compatibility before purchase , etc. ).

If you have original remote, fcc / part numbers located on the back of remote and should be exactly as one purchased.
If you provide dealer with VIN, they can check their database for info and if keyless entry system installed. When you find out your required remote'* specifics (fcc id/part number - not same as dealer order part number). Let me know. Can check for availability.

It would help to know the code, the one they list for that FOB is KOBUT1BT that is the most common I've seen, But there are more. I have BillBoost look at your thread, he knows a good deal about these. He wont be on till the AM.

Alright, gave the parts guy at the dealership my VIN, he told me yes it did come with keyless entry. He said it would need to be a 1992-1994 and the number he gave me was 256026-67. He also told me I'd need to program it and such.
