The security system (VATS/PassKey) is having problems, it's typical on those cars. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

My trail blazer 2006 wont start and it has a light on of a car with a lock what does this mean heeelp please as soon as possible emergency


You have now experienced GM's terrible anti theft security system. These systems are known for failing and will cost you an arm and a leg to fix. Anywhere from $350 - $700 plus labor. Most mechanics wont even touch these "PASSkey" security systems.You'll have to go to a Dealer mechanic. The good news is that you can bypass these systems permanently. And you're vehicle is one of these lucky ones that CAN be bypassed. This link should help you find what you need and help inform you of how this system works.

My 2007 silverado was fine when i parked it last nite..now it wont start..plenty of battery and lights..but no ignition..and the steering wheel is not locked when in park..it will not start in park, or...


The steering wheel will not "lock" until you turn it about 45 degrees from center...this is normal. If your security light is flashing, there is a problem with your security system that is keeping you from starting the engine. Try this: Set the parking brake. Turn the ignition to the "RUN" position and wait about 10 minutes for the security light to stop flashing. When the light stops flashing, crank the engine without turning the key to the off position. If it starts, take the vehicle to get the security system checked. If it doesn't start, tow it. You probably need a new PassKey sensor.

Why wont my car start even after i tried the security reset. i turned key to on position for 10 minutes turned it off then tried to start it 3 times. security light still flashes


turn the key on and wait till the security light stops flashing ( this could take as long as 30 minuets ) then turn the key off then back on but do not try to start the engine and wait till the security light stops flashing ( again this could take as long as 30 minuets ) then turn key off then turn key on and start engine.

My 2000 lesabre will start sometimes and wont sometimes. for the last wk it wont start. it has power lights work everything just wont crank whats wrong with it. jf1


Hello: Make sure the battery cables are clean No corrosion, and tight. If the security light is not flashing when you try to start it, the have a helper hold the ignition switch in the start position and you go under the car and hit the starter (not to hard) near the end that goes into the engine, If it starts then you need a starter. If the security light flashes while trying to start you have a pass key problem

Security lights flashing after battery cable removal-no start


Anytime you disconnect and reconnect your battery, the factory alarm will arm upon reconnection and the truck will not start. You have to close your doors, then manually lock and unlock the door with your key. This should turn off the security system and you should be able to start the truck.
