it shuts off when you open the driver side door....
according to my gm dealer it does not. The passlock system is in the ignition cylinder
I have a 05 Envoy XL Denali, and yes the radio will shut off when you open the door after the key is removed
relay is stuck...
Wire is fine. The guy who installed the radio connected the power wire to the wrong side of the key switch.
You can unlock the car with the remote or with the key in a door to shut off the factory alarm.
When your security light comes on and your car will not start, turn you key to the on position and wait 10 minutes. The light will go off and you need to turn the key to the off position, then restart your car.
Probably the body computer is not shutting down. Ck drivers door switch for problem. Radio should shut off when any door is opened with key off.
It means the radio is locked. You will have to insert the code to unlock the radio. You must have disconnected the battery or the battery ran down.
Put the key in the ignition and turn it to the on position. Leave in this position for ten minutes. Turn key to off then to start. This should reset the security and the car should start right up.
Try turning key to the "on" position without starting vehicle Depress accelerator to the floor six times Shut off key
Probably a problem with you key being worn and the theft lock system not recognizing it, so it thinks you are trying to steal you car because the key is not an exact match to what is programmed into the ignition switch, thus grinding but it will not start!
Go to the dealer. check starter
