2004 Malibu Maxx no crank /no start. How can I bypass the security and/or passlock system. No, the car isnot stolen. :-)

Pass lock diables fuel system not starter . Is the security light on ? car and padlock symbol ? Your best bet , take it to a qualified repair shop before you totally ruin it . Because there are no wires you can cut , jump , put in a resistor etc... There is no way to by pass this system .The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent module (TDM).
When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains a unique value, which is received by the TDM. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct, the TDM sends a random generated number to the transponder. This is called a challenge. Both the transponder and the TDM perform a calculation on the challenge. If the calculations match, the TDM sends the fuel continue password via the serial data circuit to the powertrain control module (PCM). If either the transponders unique value or the calculation to the challenge is incorrect, the TDM will send the fuel disable password to the PCM via the serial data circuit.

I had a locked car light come on in my 2006 chevy malibu, it no longer will drive. doesnt turn off, goes in reverse but when in drive, just revs like the car is in neutral, why?

The lock an car symbol is for the anti-theft system ! By not turning off, do you mean you can't turn the key to the off position or you can turn the key to off but the car won't shut off ?
It sounds like you have a Power Mode Mismatch
The ignition switch is an input to the BCM - body control module an if something happens to the system , the BCM will keep the vehicle in the last known mode Since the operation of the vehicle systems depends on the power mode, there is a fail-safe plan in place should the power mode master (PMM) fail to send a power mode message. The fail-safe plan covers those modules, using exclusively serial data control of power mode, as well as those modules with discrete ignition signal inputs.
You could have an ignition switch problem or something wrong with the BCM .
Discrete Ignition Signals Those modules that have discrete ignition signal inputs, also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 volts, the modules will fail-safe to OFF-AWAKE. In this state, the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
This is one you need to take to the dealer because they have a factory scan tool !

Changed ignition in a 1998 chevy malibu and the car will start then it will stall like it locks up but when u turn key off then try an start it it does the same thing it has a p-1626and a p-1610 codes when...

If you replaced the lock cylinder and it came with a new key, and the car has a factory anti-theft system, the new key has to be programed to the anti-theft module. If the new key does not have a small + sign stamped into it, it does not have the transponder built into it and you will need a new key that has the transponder and have it programed. Just cutting a copy of the key is only half the job Usually they will not start at all...that's the whole point of the anti-theft thing. The codes will not reset because the problem has not been fixed. Most locksmiths can do this for about fifty bucks, but not a hardware store that makes keys, or yes...the dreaded Chevy dealer. Your code reader does not have this programing capability.

Hi I own A 98 Chevy Malibu, my ignition locked n i had to put a new ignition switch in, well now my cars tellin me Something Theft Service. Im wonder what I need to do? Iv unhooked battery for hours ect...

You need to reset the theft system. To do this, try to start it. It should start and die. Then after it dies and the theft light is flashing, leave the key on for 10 minutes. After 10 min, the theft light should go out. After the theft light goes out, turn off the key. Count to 5, then restart it. Then it should work.

Installing an ignition switch for a chevy malibu

Hello. You can view a free chilton's repair manual at under ebooks. Or go to and register for free.
There is a pin sized hole that will need to be pushed in and then you will need to turn and pull the ignition.

If you are replacing this due to the anti-theft light coming on and you having to wait 10 minutes with key in on position to reset computer and theft light, then forget it becuase it won't help. It is a bad passlock system that everyone is waiting on a recall for

02 malibu won't start

If car won;t start, but turns over it may be the anti theft system. Follow the directions in the manual-turn the key on and leave it for ten minutes or until the anti theft light goes out. Turn the ignition OFF and then restart the engine. If you continue to have problems with the anti theft system, disconnect the battery for 4 or 5 minutes and then reconnect. It seems to reset the system. Found this out after a mech. had worked on the system, disconnected the battery and told me it would be 400 to 500 to replace the module. Said no thanks and drove off to never have the problem again (so far!) 10,000 mile since.
