Turn key to attempt to start the vehicle then release and let it sit for 10 min till it stops flashing. then start the vehicle. The passlock sensor is in the ignition cylinder but is really easy to replace you can switch out sensor in 30 min. or less.

The car is in theft mode and if you cant reset it with the remote key, you will need a shop to reset it for you. to try the reset with the remote, just use the lock button by pressing it twice, wait 3 minutes and use the unlock button by pressing twice, this should reset the alarm

How to re-start my car after anit theft light has come on?


you need a full charged battery or battery replaced [if battery bad and not holding charge] your remote key fob will not work if battery is dead or to weak to start car but key should be able to manually open drivers door --if its not an original key new cut or worn down [may have to jiggle in door ] your anti theft/security lock will come on when you use key in door than you have a few seconds after you open door to put key in ignition and turn to on position before alarm goes off but you need to get battery issue corrected first if key still doesnt work may need to have assistance [slimjim]lock to get in

Citroen c3 2006 anti-theft


I had the same problem.when I used my main key my car wouldn't start and I got the message "anti theft faulty". The key and the remote still unlocks and locks the doors and turns the lights on/off but it just wouldn't start my car. I was able to start my C3 by using the spare key. The main key is still faulty and if used brings up the same message.

Anti theft light won't go out


There are 2 things to try:
1) Use your key to manually unlock the driver's side door - sometimes this alone is enough to reset your security system.
2) Put your key in the ignition and turn to ON position (do not try to start the car, just turn to ON)- after 30 seconds, attempt to start the car and see if the security light goes out.

Lose tried to steal my 20005 buick rainer .iignition is missing took off plastic cover .can turn ignition to start but scurty light is on won,t start .there is no chip in key what can i do to start it?


Your vehicle is equipped with the Passlock theft-deterrent system. Passlock® is a passive theft-deterrent system that enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, the fuel system is disabled and the vehicle will not start.

During normal operation, the security light will turn off approximately five seconds after the key is turned to RUN.
- If the engine stalls and the security light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.
- If the engine does not start after three tries, the vehicle needs service.
- If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock® system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock® at this time. You may also want to check the fuse. See Fuses and Circuit Breakers on page 5-93 in the Owners Manual.

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window and open the driver's door.
2. Activate the system by locking the doors with the power door lock switch while the door is open, or with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the security light to go out.
4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

When the alarm is set the power door unlock switch is not operational. If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown.

Keep us updated.

Anti theft system came on dash. shut the car down will not start. 2002 cadillac. i was told 30 differ sensor showed wrong. which sensor to start with.


The SECURITY light is located on the instrument panel cluster.

If the ignition is off and any door is open, the SECURITY light will flash, reminding you to arm the system. To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with the door open or the remote keyless entry transmitter. The SECURITY light should come on and stay on.
3. Close all the doors. The SECURITY light should go off within approximately 30 seconds. If a door or a trunk is opened without a key or a remote keyless entry transmitter, the horn will sound and the lamps will flash for about 30 seconds.

Also can check this and other details in the 2002 Cadillac Owners Manual (page 85 and next).

Hope helps (remember rated and comment this).

Remote start not working 2006 grand prix


To get the remote start going again, I remembered a time when my Explorer phob would not open the doors automatically, I was told to insert the key and toggle it from off to "run" (not starting it, but having the radio and lights come on) position about 4 - 5 times to reset it. I tried that with the car, and it worked!!

Thanks,
Jane
