Are you able to get under the hood, if so disconnect the battery for a day, and it will reset.

I have a 2008 equinox anti theft doesnt work and starter will not engage


Anti theft is working and that's why starter isn't engaging. This may work. Turn key on and leave on for 10 minutes. Turn off for 10 minutes. Turn on and wait for security light to go off. Then try to start car. This process works on most GM vehicles that have forgotten the key.

My steering wheel keeps getting stuck


Modern vehicles are fitted with a steering lock which is an anti-theft device. It is fitted to the steering column usually below the steering wheel. The lock is combined with the ignition switch and engaged and disengaged either by a mechanical ignition key or electronically from the vehicles electronic control unit. --------------------------------------------------------------------------------

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 has engaged


sounds like the transmitter in the key head is defective or it lost programming, try these programing steps, if that doesn't do it u need another key made.

Turn ignition from OFF to RUN 8 times within 10 seconds, with the 8th time ending in RUN. Door
locks will cycle to confirm programming mode.
2. Within 20 seconds press any button on first keyless remote. Door locks will cycle to confirm
programming.

3. Within 20 seconds, press any button on second keyless remote. Door locks will cycle again to
confirm programming.

4. Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.

Replaced the alternator, now anti theft won't disable


The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:
  • The antenna for the keyless entry remote transmitter.
  • 26 circuit connector (C256).
  • 22 circuit connector (C257).
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:
  • The ignition is OFF.
  • The PANIC alarm is OFF.
  • All doors are closed.
There are two ways to prearm the system:
  • Press the LOCK button on the transmitter.
  • Open a door, press the power door lock button and close the door.
After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:
  1. Pressing the UNLOCK button on the transmitter.
  1. Placing a key in the door and turning to UNLOCK.
  1. Turning the key to RUN or ACC.
The anti-theft alarm can be triggered by the following conditions:
  • The ignition cylinder is damaged with or without the RAP being armed.
  • A door is opened without disarming the armed RAP module.
The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
  1. Pressing the UNLOCK or PANIC button on the transmitter.
  1. Putting a key in the door and unlocking the door.
  1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Ignition


If you are unable to turn the steering wheel then you have engaged your anti theft system. To dis-engage, depress the brake fully, turn the wheel all the way in the direction that it gives, and apply pressure to the key and it should dis-engage the anti theft system. If you can turn the wheel, than try the post above.
