Keyless entry problems

[FriendlyMan]

Hello again Truck masters,

 

I have a 2000 Chevy Silverado 1500 extended cab, 4.8L V8, standard transmission.

 

I recently ordered a keyless remote replacement for my truck to replace an old one that broke (had it clipped to my jeans while sawing up trees in LA during hurricane gustav a few years back, and it was water damaged and smashed moving logs). I held on to it anyway the past few years (the old one).

 

Anyway, the new one I ordered is identical to the old one, same numbers, FCC ID, etc.

 

I went online and found some instructions for programming it. The normal: hold unlock, ON, OFF, ON, OFF, release unlock--the locks cycle--hold down the keyless remote unlock and lock buttons simultaneously for 15-60 seconds until locks cycle...

 

Well it didn't work, the locks cycle fine and enter into programming mode, but when I hold down the remote buttons simultaneously nothing happens. I called tech support (the people who I bought the keyless remote from) and followed the steps with them on the phone. The tech asked me to put it into programming mode and then to turn the key to the ON and OFF position to see if the program would exit properly by cycling the locks again, and this doesn't happen.

 

He explained to me that the truck would enter programming mode but would immediately exit (or crash) and that this problem seemed to be pretty common on blazers of this year too. I asked him if I should go ahead and buy a new keyless receiver module and he said no, get it checked out by the dealership.

 

So here is what I have done so far:

 

- I tested and replace the keyless remote battery, made sure it read 3.0-3.3v (so it's not the remote battery)

- I took the remote to Autozone and tested it on one of their signal testers - the remote works perfectly

- I disconnected my truck battery for 10 minutes, reconnected it, and tried it again (no luck)

- Went to a junkyard and found an identical keyless receiver module and replaced the one in my truck (no luck)

- Tested to see what happens without a keyless receiver module--truck doesn't enter programming mode, locks don't cycle

 

I did some more reading and searching online and there seems to be a memory problem with the truck's computer? If this is so, is there a way to reset it?

 

If this is something I absolutely can't fix, what's a ballpark estimate on the cost to have someone else fix/program it? any other ideas?

Is there a way to reset the computer in the truck?

I did a little more research and found that someone fixed this problem by replacing their BCM. I'm thinking bout just getting a bulldog keyless kit with remote starting. Anyone have experience with those or know if the BCM is required for that too?

I have a 2004 Silverado with this same issue. Did you ever figure out what was causing it?
