SOURCE: theft system locked

To get the key out; look under the steering wheel for a plastic flat head screw. untwist it and then push the spring in and your key will be free. Then, go to your fuse box and remove the main fuses and you will hear the doors unlock when the system reset itself. Plug them back in and start your car. This just happened to me... seems the only things that were working were the navigation screen, headlights, fog lights, and reading light on the inside. Dash board was all dark except the engine light.

I have a 2007 cadillac cts and the check antI theft system light is on car will start no gages working key will not come out. What could be causing this problem.


The key stuck in the ignition is either a bad lock cylinder or more than likely a bad ECM. I have the same problem but replaced the lock cylinder and new key, that changed nothing. If your Anti Theft light is on and traction control, no gas gauge nor temp gauge, ECM. More and more will quit working or go crazy in time until there is no power anywhere

What is the exact location of the antitheft fuse box?


Explain anti-theft fuse box ! what do you think this is ? There is an anti-theft system on your vehicle , called PATS - passive anti theft system .Sorry , but there is not anti-theft fuse box .

My key is stuck in the ignition of my 2006 cadillac cts


2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

My 2004 cadillac cts says service anti theft system my TC light is on my gas guage & temp guage dont work key stuck in my ignition reverse lights dont work


you have a low voltage problem. either a bad battery or a brake in a wire somewhere. My sister had the same problem in her car. Had it to the gm dealer 3 times they couldnt figure it out. I put a new battery in, new wire from batter to starter, and a new altenater and wires to it. just by dumb luck i noticed the (+) wire from the bat to the fuse box under the hood was broke at the fuse box. Put new wire on it and 2.5 years later no problems.

Hi . Entered our garage on an angle & indicator light did not switch off for quite a few hours before we noticed it . Does this frequently if dont come in to park straight. Battery on our cts cadillac...


When the battery went dead, it activated the anti theft system. That is why you can't get the key out of the ignition. If you do get it out, you still won't be able to start the car. Call the dealership and ask them what your options are, in the meantime, go to this website and read about the security sydtem: http://newtockies.ca/vatsbypass.

Key stuck in ignition will not turn on think i trip some kind of anti theft mechanism only had 1 day any suggestions


If you have a backup key, try to disable system by using the key to lock and then un-lock the driver side door. This may work to disable the anti-theft mode. If that doesn't work, disconnect the battery cables then re-correct that normally is the trick. However, make sure it's not your battery. Use the unboard computer and check your battery voltage to make sure it's sufficient to start the car. The key won't eject if the battery is too low to start the car.

How can I bypass a anti auto theft system on my 1990 cadillac seville?


I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer
