03 GMC SIERRA wont turn over all accessories dead.?

Question

Today i shut off the truck,but the radio was still playing even without the key..no accessories worked,and truck would crank but not turn over.....so my husband disconnected the battery and then every thing went back to normal and we drove it home....any ideas what happened and will it happen again?

What i mean is it would turn over but not start..not catch...what would make the radio keep playing with no key in and no acc. and not turn on???please any ideas are welcome...our only vehicle....3 kids

The radio was playing with the door open and no key in.

Answer 1

you may have not gotten the key all the way to the off position when you pulled out the key this will cause this as the security system will reconise the key is gone with the accy on when you turned it off and waited 1/2 hour the security reset
and the car started get a new key code cut from the dealer this will fix it

Answer 2

Hi! I've seen similar concerns be caused by ignition switch problems. The radio should play with the key off only after you have had the key on, then it should go off after about ten minutes or so. It should also shut off if you open the door. The truck has a feature called Retained Accessory Power. From my experience the problem will probably happen again intermittently. If you try turning the key on and off several times you may be able to get it to start. I've seen some that you could watch the gages to get an idea of when it would start. If the gages didn't all work it wouldn't start, if they were all working it would start and run. (Not saying that's how it will be all the time, just something I've noticed on a few of them.) Hope this helps!
