chances are the battery is dead in the keychain. you can take it to a auto zone or other place like that they will probably fix it for you. cost about 3 to 5 bucks
Sounds to me like your vehicle has a dead battery.
The battery connection inside the key likes to break.
One reason that a keyless entry remote will not open the doors is a dead battery, either on the vehicle or the key itself. Another reason is that the remote needs to be reprogrammed.
One reason that your keyless entry may not work is that the battery is dead, take it an auto parts store and have the keyless entry battery replaced. If that does not fix it you will need to take it to the dealer to have the keyless entry reprogrammed.
If the dome light and the keyless entry system does not work on a Nissan Sentra it is possible there is blown fuse. The fuse box is found in the passenger compartment.
Start vehicle and then hold both lock and unlock buttons on remote for 10-20 seconds, locks will activate and should be programed.
Your remote might need replaced, the buttons are probably worn out. They usually don't last for 10 years!
the batterys in your keyless remote may need to be changed
how do you program a keyless entry remote to a 2000 Pontiac grandprix programyourremote.com (program your remote.com)
The battery on your clicker is out of batteries
You don't. You have to maintain the factory radio in the car somewhere or the keyless entry will not work on 96-98 civics.
The batteries may be dead on the remote.
