P.*. I forgot your first questions...

Yes. A bent paper clip will do. Actually the upper-right port is just a convenient ground connection; it'* grounding of the lower-left connection that puts the car into Learn mode.

you need to go to the dealership. Give them you vin number. They can run it and see if your car has Keyless Entry. That is what i had to do with mine. I just asked them and then my friend (Drop Top Olds) used the paper clip to the pins. I found my remote at the boneyard for .50 and had it programmed in for nothing I am so glad to have yall here at bonneville club.

1) Really? How far does their database go back, anyway?
2) I'm sure you probably can go to all that trouble, but really, just look in your trunk first. The car probably still has its RPO code sticker, and all you need to do is locate "AU0" on it, the option code for Keyless Entry.

Fifty cents??? Do they have any more?

Me too! Me too!

i know that they at least go back to 1994 and i think 1992 is as far back as they go. NE ways, it is free, very worth the while. I can also look next time i go to the boneyard and see if they have any more. They are usually left in the cars. Also, this one place i frequent has like 25 SSEi Bonnies and a gazillion SE and SSE ones as well. Almost all the parts are prime for the pickens. I got a hold of one the other day that i was the 1st one to touch it, what a thrill. I nabbed almost everything i needed for my car!!! Only 20 bucks also. Ne ways, back to the subject, there is something in the VIN number that they can run and let you know whether your car has keyless entry on it already or not!!!

Jumping the pins 4 & 8 causes the locks to cycle on my '96.
My original key flob GM/UTA# 25628814 & FCC# K0BUT1BT.
I purchased 2 used flob'* with GM/UTA# 10246215& FCC# ABO0204T and these wouldn't program.
Then I just purchased 1 new flob with GM/UTA# 25668603 & FCC# K0BUT1BT and it doesn't work either.
Does the GM# need to be exactly the same?

Okay... The lock cycling is usually how it acknowledges learning mode; at this point you would press precisely one button (any button) on your new key fob, and the car should acknowledge you again. I suggest that if your original transmitter will work on this step, but the others you bought do not, then the others are unfortunately not the right ones (or else they're not working).

It'* FOB, not FLOB, okay?

Okay... (I assume you checked the batteries, etc.)

I would think so. You bought new... from a dealer? They looked it up and verified that you were buying the correct part number for your year and model? Does it look the same as your original?
