Hello, don't know if you are aware that you have to "program" the remote when you take the battery out. If it's not any different between a couple of years of age you should be able to do this.
Stand a couple of feet away from the drivers side and then press and hold down both lock and unlock buttons on remote until the locks start to cycle,(locking and unlocking themselves). You should be good to go after this. If it is a new fob you have to have the dealer program it to your vehicle. Hope this helps you out-or in, whichever the case may be! 8)

Suggested Repair

After replacing the keyless remote battery, reprogram it by standing a couple of feet from the driver's side and holding both the lock and unlock buttons until the door locks cycle. If the remote is a new fob, have a dealer program it to the vehicle.

Conversation Summary

The owner of a 2003 Chevy Blazer Extreme replaced the keyless entry remote battery, but the remote still does not work. An expert said the remote must be reprogrammed after battery removal by holding lock and unlock until the locks cycle, and that a new fob requires dealer programming. A second expert agreed.
