I have the keyless entry system on my car but my remote wont open the doors. I checked the battery in the remote and replaced it with a new one and it lights up ok. Do u guys know how to activate it from the inside. Maybe a fuse or something?????

 

you probably placed it in valley mode somehow.. what type of remote entry/alarm system? maybe someone here might know a way to take it out of valley mode. If not luck, contact the manufacturer or installer, or check manual.
