Keyless Remote Entry stopped working

I have a 2000 Oldsmobile Alero that I bought recently. It came with keyless remote entry. It worked for about a month and now has stopped working. I don't think it worked that good to start with, as I could only use it from about 15 feet away. I'm wondering what do I need to buy/fix to have it work again. Any help is greatly appreciated.

Sounds like your battery has died.

Pretty cheap at walmart and other stores like that.

the remote pops apart from the bottom corner. :thumbsup:

Thanks. I replaced the battery and it's still not working. I opened it up and the metal piece that holds the battery in place has come off on one side.

In most cases, you can press down the broken connection and dab a little superglue to secure it. Once you change the battery, hold down LOCK & UNLOCK on the remote for 7 seconds to resync it to the vehicle.

That didn't work either, but thanks for all your help. I decided to buy a new one off ebay and that's working good. Thanks again tho!
