the ignition key turn all the way back, stuck?

Check fuses, check body grounds for damage. Also, is the park lock solenoid working properly? In other words, does the vehicle only come out of park if the brake is depressed?

Electrical problem
2006 Cadillac CTS 6 cyl Two Wheel Drive Automatic

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 2007-2010 Cadillac STS 2006-2010 Cadillac CTS Sedan 2009-2010 Cadillac CTS-V 2010 Cadillac CTS Sport Wagon Equipped with Automatic Transmission 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.

The dealer says that the adjustment above didnt fix the issue and it needs a new mircoswtich which is part of this assembly, however one much buy the entire assembly and not just the switch?
If you have the switch only part number, as well as the full assembly part so I can find prices elsewhere I appreciate it.
Also, you refer to other chart or links above in the OP and I'd love to have those as well.

Last, they said the seizing calipers require entire brake system replacement... any chance the issue above is telling the brakes to activate?

In Boca raton area and could use a mechanic recommendation!!

must turn key on and off 3to4 times to start engine,or the engine will die in10 to 20 seconds after running.

Check fuel pressure to start with.

may be the fuel pump loosing its prime. that would require replacing the pump.

have the pressure checked when this happens

When I put my key in the ignition it gets stuck the car would start and crank but the "service theft system" message on the DIC and when that happens the theft icon shows and so does the Traction control icon, the steering becomes stiff and the DIC won't show information about the fuel and neither will the fuel work. What could be the cause this and how expensive could the cost probably be? I've read that the ECM is going bad and.....

It could possibly be due to faulty ECM. Does the battery seem healthy?, low voltage during crank may cause problems, as well as communication data line fault. It would need some hands on diagnosis to get an accurate idea, and this is going to be your cost variable.

Thanks, I've been reading info that lead towards the problem being the ECM. The battery is always showing around 13.9- 14.6 voltage on the DIC, although I have experienced problems sometimes when the car wouldn't start on just two occasions....

my key will not release. Oil and fuel gages will not work. The theft llight and traction control light will not turn off. When the gages dont work the shifter light will not turn on and I do not know what the gear is on. I am a mom carring a baby around. My only ride please help.

Without saying you would need to have it checked for fault codes, try disconnecting both battery cables and touching them together for a minute or so. If you can't get them together, use a jumper wire. See if all the symptoms correct. If it resumes the same action, it will need some diagnosis, starting with a diagnostic systems check for fault codes.

2004 Cadillac CTS V8 Two Wheel Drive 50000 miles

unable to remove key

Does the ignition rotate, car start? What is the security light doing, is it on solid? Try disconnecting both battery cables and touching them together for a minute or so. Restore power and see if functions return to normal.

the ignition switch will not release the key when i go to turn the car off, what should i do

Try putting a little pressur on your gear selector. Push it forwards (Towards park) and remove the key at the same time.

If this works, then you have a bent linkage/bad bushing in the gear selector mechanism.

If it doesn't work, then you possibly have something binding inside the ignition lock that is preventing it from turning completely to the "Off" position.

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. The brake lights do work. When the car originally wouldn't start we found that the negative battery cable had stripped out and was loose. Would that have caused this snowball effect of different issues. Any suggestions?

At this point I feel confident that is deals with the security system or the shift interlock solenoid. 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.

It could be a battery that has shorted internally. I have seen this before.

Here are to guides to help you test and then replace the battery

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.

Also check the shift lock fuse that could be out as well.

Let me know how things go for you.

i have the same issue with mines. i will go ahead and do what you recommend jacobandnickolas

I have the sport model of cts. I drive it in sports mode. I have had this issue happen a few times. While driving, the car engine feels like it is maybe trying downshift or slows me for like a sec, then takes me out of sports mode also. Today when it happened the engine light flashed on then off. When it does this the message on the screen displays this ....Starting disabled/ remove key, then goes away. Any info on this will be helpful.

Hello,

It sounds like the battery has gone bad and has a short circuit, Here is a guide to help you get the problem fixed.

Please let us know what happens.

Cheers, Ken

My key will not turn all the way off and I brought it from dealer with metal key. now it is not reading anything and will not start or turn off lights in car. I really do not know what to do. I do not nor never had the original key? The key will not turn?

The way I'm reading this is the ignition switch will not turn all the way off. If this is correct it sounds like you have an ignition switch that has gone out or a shift cable that is coming apart. I would check the cable ends at the transmission and at the shifter. If that looks okay the ignition tumbler is jammed and needs replacement, here are some guide to show you how to do it. It could be the transmission linkage as well.

the key is stuck in the ignition and wont come out its in park and shut off and have tried to move it and try again and still nothing

Can you still turn the key?

yea it still startand everything just wont come out lol

Try putting your foot on the brake (key in ACC postion) and pulling up the switch on the gear shift lever.

didnt work and none of the light on the shifter coloum work

My key is stuck in the ignition and won't come out. the message is that starter disabled,remove key.
I have tried to unplug the battery cables to reset the computer and that has not worked

It must not be all the way in park, try turning the key back on and take the shifter out of park to neutral and put it back in park see if the key comes out.

Okay, disconnect your negative battery cable and reconnect it after a few minutes. Let me know if this helps.

Does it still start, or is that prohibited?

Hello, please help! i go crazy with my car. I leave in Europe (Georgia, Tbilisi) and we don't have Cadillac dealer, so i only can write you. My problem is: key stuck in ignition, service theft system message, fuel gauge not work, parking position light not work in this time. I can only start engine from starter relay manually (i remove starter relay and start engine from there). I ordered re-manufactured and programmed ECM, but i cannot do key relearn procedure. seems like i lost something between Keys Off and On Position. Can you please help me?

What happens on these cars is the shifter needs to be adjusted causing the ignition key not to be removed. here is a guide to help you see what you need to adjust. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Dear Ken, Thank you very much for fast answer! OMG, i think i also thought about something like this. because, my car have some noise when i shift to parking position. Please explain to me, where is this located? With diagram i do not understand, where it is. is it under gear shifter? or under the car? do you mean maybe transmission linkage like in this video? https://youtu.be/hmLBPin6ggw i am not professional mechanic, but i know many things and hope to fix it myself. So, please, explain me little bit more detailed, what i have to adjust or replace. Thank you in advance! i am big Cadillac fan, but unfortunately we don't have official dealer service in Tbilisi, so i cannot do anything.

that is exactly what goes wrong it is under the car. here is a guide you can follow to raise the car safety:

https://www.2carpros.com/articles/jack-up-and-lift-your-car-safely

Can you please shoot a quick video with your phone so we can see what's going on? that would be great. You can upload it here with your response.

Dear Ken, Thank you very much for helping me. i think, you are my last hope :-) because, everyone was saying ECM, TCM, low voltage, etc. Only you say to me about and after your message i start to think about this noise and this thing. I have now video, i hope it uploads here, when not i will upload it on YouTube to show you everything. Important thing: this happens not exactly every time. For example, yesterday i was trying to shoot video, but car started normally with the key :-)) funny, but true. and after car starts normally, it needs some time, some hours, for problem come back. today car was not starting and finally i have video now and i will upload it now here. P.S. after starting from starter relay i have two error codes: U0100 (Network) and P0700 (Transmission Control System MIL Request). P0700 is not every time, only sometimes. Hope, this video and my comments helps you to help me. So, can it be Shifter adjustment, what i need for fix this problem? as you know, i do not leave in USA, i am in Europe (Georgia) and we don't have here official Cadillac service. Thank you so much for helping me. wait for your answer.

The network code is most likely the PCM, can you remove the electrical connector at the PCM to check for corrosion? Here is the location. Also I have included the security relearn institutions. Check out the diagrams (Below). Please let us know what happens.

Dear Ken, no, there is no corrosion at the PCM. Connectors are also okay. We also tried install a new, programmed ECM but key relearn procedure can not be done. But with old ECM sometimes is everything okay. Sometimes Car starts absolutely normally! did you see my video? one day ago car has started normally with key. Do you think after this video about shifter adjustment? or no more? i think also about this detail under the steering wheel (please, see Photo, i don't know name of this part). because, when i try to start and car can not start with the key, sometimes this detail is heated! or maybe my key is damaged (please, see also key photo).

Yes I looked at the video and it looks like the immobilizer is broken, here is the security wiring diagrams and a guide to help you test the wiring as well. When it doesn't run is the security light flashing?
