ls1 key fob problems

I have a 2000 trans am, the fob that i have wont program with the car, or somethin wierds happening. i do the off-on 3 times, with the radio fuse out and the doors lock and the trunk pops like described, i then hold the lock/unlock buttons for 15 seconds and nothing happens? replaced the battery 3 times tryed both sides, still nothing. I took a fob from a grand prix, same buttons, same #'s on the back of the fob, tryed 2 program it to my trans am (just 2 see if it was just my fob was broke) and it still wouldnt program with my car. any ideas? maybe if i disconnected my battery and reconnected maybe it would reset something?:confused:

Is it a replacement fob, did it work before? I'd look up the FCC ID# at http://autotechs.com/fcc/fccidsearch.htm For GM it also gives the PN that matches it and what models/years they work on in most cases.

i matched my numbers w/ the ones on the site, and it didnt say nething about a trans am, but i also looked through every one similar looking to mine and saw nothing about camaros or trans ams/firebirds,

Post the FCC ID number/part number on your remote, might be the wrong one. For instance KOBLEAR1XT has different part numbers for different GM cars/years but can look the same.

The dealer has to program it for you.

Dealer doesn't have to program it - seen posts where people bought cars without one, had the RPO code, bought one and programmed it and it worked fine.

FCC ID: ABO0204T
gm: 10246215

Although it looks the same, believe that's the wrong remote.

I think you need this one

FCC ID: ABO1502T ( AB01502T )
GM: 16245100-29
Canada: 218101368
