why aren't my remotes working for the keyless entry?

I have changed the batteries but they still aren't working? has anybody else had this problem and can help me out? I hit the button to unlock but it still doesn't----It's not the battery

does it lock? You may have to clean the rubber inside the remote with alcohol and the contacts with an eraser.

If it locks the car then there is a relearn you can do...
Lock the doors and then hold down both buttons for about 20 seconds until the horn beeps.

no it won't lock them either. any other ideas?

On my Aurora, the remotes quit working. I purchased new batteries. I was changing them I found that the ring that holds the batts. had broke their solder joints. I got my gun and redid them. They work fine now.

Would this proceedure also work with the 2001 model?
