My viper alarm just stop responding out of no where. When i press lock/unlock the light on the remote lights up, but the car doesn't respond. The LED light in the car is off also. I think it has to do something with the LED light not on, but i don't know how to fix it. Anyone knows how to solve this problem?

 

Do you know were the valet button is?

 

Yes.

 

Lets try to see if the alarm brain is still working. We are going to try to reprogram the remotes. Turn the ignition on were all the cluster lights turn on. Make sure the driver door is open. Press the valet button once and hold it. The cat should chirp once. While holding the valet button down, press lock on the remote. You should get a chirp when you do. Then turn the ignition off and arm the car.

 

Nothing happens when i press and hold the vallet button. It doesnt chirp or anything.

 

Okay. Can you get to the brain and check the fuse. If its blown then replace and repete or arm the car. If not check to make sure its getting power. If so then the brain is gone and needs to be replaced.
