Not Working remote entry.

I have a Sunfire 2001. Some days ago, i had problems with my car battery. After i replace it, i started to get problems with my remote entry. It doest work an funcion. (lock, unlock, panic, trunk). I tried rotating the codes pushing lock/unlock at the same time and doesnt work.
I checked the battery and replaced of the remote entry and doesnt work.

Anyone have any idea how fix that?


Thanks!

If your batteries die, or you replace the batteries, try holding LOCK and UNLOCK down for 7 seconds to resync the remote to the receiver. If that fails, your remote may have died off. Its not too common, but does happen on the ABO1502T GM units.

which die? the module alarm of my car or the remote keyless? i hold both and i dont get response.
I checked all fusibles and all are ok!

The remotes themselves can just die over time. Heat, Cold, water can all do them in. Sometimes, they just die for no reason.
