last week my remote control couldn't open my car anymore.. i thought it was a bettery problem.. bought new one yesterday.. replaced it but it would still not open my car.. and I see the alarm light on (all the time) when the car is closed... any ideas?
is there any fuse connected to the alarm?

 

You have to program the new remote to the alarm brain in order for it to work. If you still have the manual it will explain how to do this. Once this is done your problem will be fixed.

 

How would that resolve the problem ? From the sound of the symptom it is in valet. Programming any remote to the system would not take it out of valet without actually taking it out of valet.

OP .. what system is in the vehicle ?

 

Misread the op's post. Thought he said he bought a new remote and not a new battery.
