    Running Lights?.. Parking Lights/lamps?.. let's clarify. How bout' brake lights? only when you press them?.. sounds reasonable to me. You sure we're talking about the same lights? I can only presume when you say 'running' lights, you're talking about 'parking lights' and when you talk about the running lights in the back, you really mean 'brake lights' since they only work when you press them. Tell you what, a whole lot of clarification is need here before any progress can be made.. ya thing?.. do you agree?

Can't get key out of igntion on my 2004 endeavor

Assuming there's no button to press when taking the key out, try rocking the steering wheel to left and right at the same time as trying to remove the key. Sometimes the ignition lock engages at the same time as the steering lock.

My 2004 Impala won't start. Computer message is

try anoth igntion key, if not a good moble auto locksmith should be able to diag this, if he can't you'll need to tow it to your local GM dealership. It could be the igntion cylinder, but there is more items involved in the security system besides the igntion cylinder & you need the proper test equipment for testing.

Seabring igntion switch locked 2004 the key wont turn either way, or start the car

Sounds like the steering is locked up, go in the car and rigirously turn the wheel in either direction (shake from left to right), this will free up the steering and allow you to turn the key.
