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.

SOURCE: 2003 Cadillac CTS - the car won't shift from park

sounds like you have a bad brkae light switch, which is located on the brake pedal assembly. a bad switch will not let you shift out of park and you will not have any brake lights as the car does not recognize that the pedal is being pushed and brakes engaged. easy to replace switch if you are handy, if not this is a inexpensive repair at any mechanic. hope this was helpful is so please rate 4 thumbs.

I have a 03 cadillac cts the other day after work i go get in the car try and start it up the radio part reads anti theft / service theft sytem and does not start and also said remove key... what the


The vehicle is having problems reading the tiny metal security slug in the ignition key. When you used a key to unlock the door, you disabled the security system so it started. There are a variety of different resistance values on the slugs in the key. You can have someone with a ohm meter read the resistance of yours and install a fixed resistor of the same identical value to the wiring for the key security system. You may alternatively spray contact cleaner or a bit of WD-40 in the ignition switch to clean it off. Insert and remove the key several times, wiping it off each time you remove it.

in most vehicles they use a steel wire to connect the turning of the key-ignition with the shifting lever. if this cable is broken or out of adjustment, it could cause a problem like that. just an idea.

My 2003 cts won't start when it's cold outside. I've checked the battery SnF the alternator and I also had a new fuel filter and pump put in. Sometimes when it doesn't start it'll say service theft system...


Have your dealer or a qualified Cadillac mechanic check the anti-theft system and your key. Your ECM may need to be re-flashed, but have a diagnostic scan performed to determine possible solutions.

There is a magnetic switch on the 'park' position. The car only starts or releases the key in 'park' is enabled. Maybe this switch is not working! Try to replace it!

I have a 2007 Cadillac CTS. I go to turn the key and nothing happens. All onboard elctronics and a/c are functional. Battery life shows to be good. I have also tried using my other key set and nothing....


Test the neutral safety switch by doing the following steps.

1)foot on brake
2)turn key to on position
3)shift lever to neutral (N)
4)start the engine
5)shift the lever to Park (P)

If the engine can start at N and not at park then it's the neutral safety switch.
