Today my cts shut off after I started it then wouldn't start and the anti-theft light is on. Ten minutes later it starts but won't shift out of park and the key won't come out and the anti-theft light remains on the entire time. It has a brand new battery. Any suggestions?

Do you
have the same problem?

See if the gear shifter is all the way in park, if so check to see if the battery is dead, the vehicle will not come out of park and can cause a problem getting the key out. The shift lock solenoid needs power to release from park. See if the brake lights are working. The brake light switch controls the park lock.

WE have a repair shop we use for our vehicles. Would they have the equipment needed or do dealers only have the test equipment?

Most smaller shops don't. However, yours could. Do me a favor. This is going to sound stupid, but check to see if your brake lights are working and let me know what you find.

The brake lights do work. When the car originally wouldnt start we found that the negative battery cable had stripped out and was loose. Would that have caused this snowball effect of different issues.

That is a good question. I asked about the brake lights because power goes through the brake light switch and to the park interlock system. If the brake light switch fails, no power goes to the solenoid. Thus, you can't take it out of park. I was hoping for something easy.

Regardless, at this point I feel confident that is deals with the security system. Something triggered it into lock down. It is odd that the neg battery terminal did that to you. Either someone over tightened it or it was left loose. However, that could have been the start of the entire problem.

I have three things for you to try before the shop. First, disconnect the battery (neg terminal) for a couple minutes and then reconnect it to see if the system will reset itself. If that doesn't work, remove the neg terminal again then the pos. Hold them together (away from the battery) for about 30 seconds and then replace and see if that resets it. Finally, turn the key to the run position and let it sit (not running). The security light should go out after about 10 minutes (over riding the security system) and then start it and check if that helps so you can at least drive it to the shop.

Let me know how things go for you.

Car has been at our shop two weeks now. I think we were better off taking it to Cadillac. Our shop is currently trying to reset the security system.

THE ALARM CAN BE RESET BY LOCKING AND UNLOCKING THE L/F OR R/F DOORS USING THE KEY IN THE DOOR KEY CYLINDERS. GOOD LUCK

The Ignition will not turn completely to off, almost as though the gar is not in park. Although the transmission is in park, either the shifter or ignition does not recognize it.

For starters, reference this bulletin. See if it helps.
#07-07-30-032C: Shifter Binds, Ignition Key Sticks, Shift to Park Message Displayed On Driver Information Center (DIC), Dead Battery (Adjust Shift Linkage) - (Jan 8, 2010)

Subject: Shifter Binds, Ignition Key Sticks,"Shift to Park" Message Displayed On Driver Information Center (DIC), Dead Battery (Adjust Shift Linkage)

Models: 2007-2009 Cadillac STS-V, SRX

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 07-07-30-032B (Section 07 -- Transmission/Transaxle).

Condition
Some customers may comment on one or more of the following conditions:

" The shifter binds when putting the vehicle into gear or park.

" The ignition key sticks or is hard to remove from the ignition lock cylinder.

" The "Shift to Park" message is constantly displayed on the Driver Information Center (DIC) when the shifter is in the "Park" position.

" A dead battery that follows after parking the vehicle for an extended period of time (less than 24 hours). This vehicle may have been left in accessory mode with the "Shift to Park" message displayed.

" The shifter binds when moving the lever from Drive to Manual mode.

Cause
This condition may be caused by the shift linkage adjustment, a slow Brake Transmission Shift Interlock (BTSI) mechanism or a Park Confirmation micro-switch that is not closed.

Correction
Adjust the automatic shift linkage following the steps below.

Verify the customer's concern.
Position the shift lever into the PARK position.
Check for any stored diagnostic trouble codes (DTCs). If any codes are set, diagnose the DTCs first using SI.
Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
Adjust the automatic shift control linkage. Refer to Shift Control Linkage Adjustment in SI.
Lower the vehicle.
Tip
If the "Shift to Park" message is displayed, try wiggling or "bumping" the shifter while in the PARK position. If the message goes out, then repeat the adjustment. This is typically an indicator that the shift linkage is biased rearward. If the initial condition was Drive to Tap Mode binding, then the shifter linkage was initially biased forward.

Determine if the condition has been corrected. If the condition still exists, the automatic transmission shift control may need to be replaced. Refer to Automatic Transmission Control Replacement in SI.

Shift Control Linkage Adjustment
Position the shift lever in PARK.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Notice: Refer to Fastener Notice in the Preface section.

Loosen the shift control linkage adjustment nut to allow the adjuster to slide freely.
Hold the selector lever on transmission against the rear stop to eliminate any play.
Tighten
Tighten the shift control linkage adjustment nut to 9 N m (80 lb in).

Lower the vehicle.

Inspect the operation of the starting system with the shift lever in each position. The engine should only crank when the lever is in the PARK or NEUTRAL position.
If the key is stuck or hard to remove from the lock cylinder or there is a high button effort, the linkage may not be adjusted properly. Re-adjust as necessary.
