Because you disconnected the battery you have set the security system on and it will have to be reset. Try putting the key in and leaving it in the on position for 20-30 minutes, shutting truck off and then try restarting. Short of that you may have to call the dealer.

2000 pontiac montana security system locked and it won't start. The information center on the van shows as follows; Low battery light, Then Security light, Then Low fuel light. Its full of gas. Help?


Does the security light come on when you turn the key to run ,Does it go off in a few min. The proper way to reset the anti-theft system would be to turn the key to the on position for 10 min. if the light goes out in that time ,turn the key off for a few seconds . Then try an start the vehicle . If light comes back on an won't start there is a hard fault . You mite at that point wan't to do a theft system by- pass . Also have your battery checked and or charging system . A low battery , a malfuctioning charging system may cause these type problems .

Its cold battery is charged dash lights come on and all bells and whistles are going off but no turn over of the engine


Possible starter problem or power supply to it. You can try tapping on the starter with a blunt object ( tire iron etc ) while holding the key in the crank position. If the vehicle starts, the starter will need replacement

I have a 2005 pontiac grand am. Battery went dead jumped it. Got home as getting dark the lights are flashing on and off. Even when the car is off until battery is dwad. Any help appreciated.


The low or dying battery may have tricked the alarm to set off. Have your battery tested. It will have to be charged up again first, but it should be fully tested. Either it or your charging system may have a problem to cause a dead battery in the first place.

When you have reinstalled a good battery, turn the key to on and observe the security light and the check engine light. They should both come on as a bulb alert that both are working, and the security light should turn off in about 5 seconds. The check engine light should go off as soon as the engine is started. If all systems go, so far, then now would be a good time to do a simple test of the charging system. Anyone with a voltmeter could do it.

2003 Aurora, left key on and battery went dead. Recharged battery. Won't start. Turn key to on, security light out and check engine light on. Move key to start and nothing, back to on, one minut


Very interesting site here.. regarding your problem. http://vatspasslockpasskeysecurityhelp.yolasite.com/
Another thought.. even though you charged the battery, it's not at all uncommon for a car battery to be very damaged by fully discharging. Especially if not new-ish. One or more cells in it may be bad causing the overall voltage to be under normal. This alone can cause the problem you have. I would try jumping it with another car or test the battery to see if it's got at least 12.7 to 12.9 volts when sitting doing nothing. Good luck.

The 'theft system' light does not turn off with the key in the run position on my 1999 chevy cavalier. car won't start, it won't even crank over. the battery and the starter are brand


try locking your car with the key and unlocking it with the key, leave it for 30 second or so between the locking and unlocking , the car thinks some one has tampered with it

I had a fuel pump replaced and after the job was done my battery was dead so It was taken out and charged up now my anti-theft light and the car won't start,days' later I came out turned the key it...


is the security light still on? a quick test is to remove the negative terminal on the battery for 10 minutes. reconnect and see if car starts without the security light on.
if the light remains on turn the key to ON without starting engine and leave it for 10-15 min until light goes out and then start the car, it should then stay running when you open the door.
the late 90's into 2000's GMs have issues with their security systems acting up, unfortunately your car is one of the ones it affects.there is no way to disable the system because it is part of the ECM
always unlock driver door first when using the key, there is actually a sensor that the computer reads, if the door is unlocked without a key such as using a slim jim or coat hanger the system will trigger a no start and the light will be on.

My entire system has shut down, and someone said it's the security system. Where's the switch or reset button?


>security system. Where\'s the switch or reset button?

If it was that easy why have a security system? GM does it again.

This worked on a 2000 so try it and see if it works on yours.

(1)Turn key to crank & then release. Security light still on. Wait till it goes off (maybe 15 minutes)
(2)Turn to off. Repeat step one.
(3)Turn to off. Repeat step one.
(4) Turn to off. Wait 20 seconds and start car.


Key must go to full off on each pass. Must have fully charged battery. Good Luck.

Even if this does not work a good testimonial would be appreciated
