Thanks all. Those are all good solutions. What I'm finding is that even when I "relearn" the remotes, they somehow "lose" their memory. The DIC says I need new batteries in them. Replaced those. Now, it won't even go into relearn mode (no beeps when I press the lock/unlock buttons simultaneously). Now, the remotes don't work at all (must lock/unlock with the key).

I think a trip to the dealer is in order.

 

turn off the seat memory recall in your 'dic'. i had the same problem

 

I am new here so hi all I just got a 02 Trailblazer and it has no owners manual and i have tried everything to set the seat memory but i still cannot figure it out any help please

 

Go to mygmlink and register. You get access to an online owners manual plus other goodies.

Is this an LTZ feature? I have the memory seats on my LT3, but the fobs are not numbered.

 

LT3, 1 week old, no numbers on my FOB's either. There are numbers on my corvette FOB's though.

 

They WERE molded in the past. That way they didn't wear off. The last generation to be marked were "painted" on. Now there are no markings at all.
