My 2001 Chevy malibu wont start. Why doe the theft/security light stay on. I work at an auto repair shop and this is a customer. Can you help me fix it? Thanks.
Answer: Hello and welcome. You should have the computer scanned for codes. But most likely your problem is with the ignition lock cylinder causing the theft/security light. You will need to replace the Theftlock cylinder and then have the system re-learned.
Thanks for the tip/donation! I will e-mail a step by step procedure with pics. Since you are going to do this yourself....
Question: Yes I have a 2004 Chevy Malibu it won't start.
Answer: Does the engine crank over?
It tries. I have replaced the fuel pump, ignition coil and just tried to reset the Passover sensor.
Can you be more specific as "It tries" does it crank and crank and crank or not at all?
Not at all.
Is the theft or security light on the dash with the key in the ON position?
Yes it's flashing.
OK. then you have a Passlock Problem. Most likely the sensor- which is part of the ignition key tumbler cylinder.
What do I need to do to bypass this is there a fuse I can pull cause the whole thing of trying to reset is just not working.
No fuse to pull. See this link for GM Passlock Replacement Procedure. Or, There are some instruction on bypassing this system around the internet, i have not tried them. It requires cutting a few wires and soldering a few together on the back of the ignition switch.
Exactly where can I find this?
Dont have an exact website, but a Google search for "GM Passlock Bypass" should give you many results.
