Ok, so I have done a ton of searching and to no avail. I was going to reprogram a keyless fob to my 2000 GT and couldn't due to the bcm having a code in it. When I get the code it is 1(long pause)2(short pause)1(short pause)2(short pause)1​(short pause)2 ..... Any help would be greatly appreciated.
 


pretty sure you need a dealership to reprogram a new or used bcm into your car.

your getting a code for the bcm? if so post it. and its definition. it can help.
 
The only way I know it has a code is when I try programming the key fob to the key-less entry. It initiates what I have found on other forums to be "the bong test" where it tells you the code by chimes. only problem is that I can't find anywhere that tells what the codes mean. I put the chime sequence in the first post. Thank you for any help....
