Security system apparently security system has disabled car so it won't start, What can I do to get it started ? Thanks...Gordon

Is the security light on the dash turned on ?
If so, there is a security error causing the problem.Fix the security problem and the other problem goes away.

Does it not start or not crank ?
Do you see a security light on the dash ?

1999 GMC Safari is equipped with a PassLock* system. It is designed to disable engine starting unless the ignition lock cylinder rotates correctly when the proper key is installed. The system is similar in concept to the PassKey* system. However, it eliminates the need for a key-mounted resistor pellet.
The components of the PassLock* system are as follows:
> The ignition lock cylinder
> The ignition switch
> The PassLock* sensor
> The PassLock* module
> The security indicator
> The Vehicle Control Module (VCM)

If any of the components (with the exception of the security indicator) is replaced, the PassLock* sytem must be reprogramed before engine start will be enabled.

When the system malfunctions, it is necessary to retrieve fault codes from the VCM to correctly determine which part of the system is causing the problem.

you disable it you disable car theirs a reason its called a security system have another key cut

THERE ARE MANY POSSIBLE CONDITIONS THAT COULD PREVENT YOURCAR FROM STARTING. 1. NUTERAL SAFETY SWITCH IF THE CAR HAS AN AUTOMATICTRANSMISSION. 2. CLUTCH POSITION SWITCH IF THE CAR HAS A MANUAL TRANSMISSION.3. BRAKE PEDAL SWITCH. MANY NEWER VEHICLES HAVE A SWITCH ON THE BRAKE PEDAL ANDIF THE PEDAL IS NOT DEPRESSED WHILE TRYING TO START THE CAR, THE CAR WON'TSTART. ANOTHER POSSIBLILITY IS THE SECURITY SYSTEM. DOES THE CAR HAVE ASECURITY CHIP IN THE KEY? THESE ARE SOME OF THE MOST COMMON REASONS THAT A CARWON'T START FOR NO APPARENT REASON. HOPE THIS HELPS.

The security system does not disable the starter, it only disables fuel to the engine. In the fuse block under the hood, locate the STARTER relay. Place your hand on this relay and see if it clicks while someone else turns the key to start...if the relay is ok then the starter itself is faulty. Good luck, i hope this helps.

Sometimes the antitheft security system can disable your starter and/or injectors. This could be your problem. This link might help you out. http://vatspasslockpasskeysecurityhelp.yolasite.com/

The security system (VATS/PassKey) is having problems, it's typical on those cars and it gets worse till the car won't start anymore. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue with the same system.

you need to get a new key made and coded

You need to buy a remote key fob and have it programed.The factory security system can't be easly disabled.
