Ignition fob key will sometimes stop in acc position when turning off and will not release key

Climb into the vehicle and close the door. Insert the key into the ignition but do not turn on the vehicle.
Hold down the "Unlock" button on the driver's door while turning the key to the right to the "Accessories" position. Continue holding down the "Unlock" button.
Turn the ignition key back to the "Off" position while continuing to hold the "Unlock" button then return the key to the "On" position again. Then return the ignition key to the "Off" position. As you complete this sequence, the doors will lock, and the horn will sound, indicating that you've entered the programming mode. At this point, release the "Unlock" button on the driver's door.
Push both the "Lock" and "Unlock" buttons on the key-less remote and hold them for roughly 15 seconds. Release the buttons when the locks click again.
Insert the key into the ignition and turn it to the "On" position. The horn will honk once more. This indicates the programming has been successful.
Remove the key from the ignition. Climb out of the vehicle and try locking and unlocking the doors with your remote key.

• The H3 uses a Tech ll code system that often cannot be re-programmed without the help of your local dealer. If you are unable to reset your key-less fob using the steps above, your local GM dealer will be able to help.

2009 Dodge Grand Caravan car lock doors not working

Insert key into and remove it from ignition more than six times in 10 seconds. When the hazards lights will flash twice insert key into ignition and turn to ACC position.
Then push any button on key fob once, the hazard lights will flash twice. Then open drivers door to END.
Should be all working again.

There are several methods of doing this - but your 2003 requires that you either go to the dealer for them to add a FOB with special equipment (ask if they'll do it for free - can't hurt). If you have time to kill, you can do it yourself with Method 3 as described and found at:

Key Fob Reprogramming General Cadillac Forums

Method 3 - Key Fob Auto Learn


This procedure will first erase all known key fobs. The procedure will then program a single or multiple key fobs. Method 3 is a series of three 10-minute key cycles, for a total of 30 minutes. This procedure requires that you have a replacement key fob and the vehicle mechanical key.

Important: All previously programmed key fobs will be erased upon completion of the 30-minute programming procedure. The order in which the key fobs are programmed will determine its numbering position within the RCDLR memory. The first key fob programmed will be key fob #1, and the second key fob programmed will be key fob #2. The number stamped on the key fob case is for reference only: #2 can be programmed as #1.
Do not place any known good key fobs in the vicinity of the vehicle when programming with Method 3. If the RCDLR recognizes a known good key fob during Method 3 programming, the programming mode will resort to Method 1.


The vehicle must be OFF.
Place the replacement key fob in the console pocket with the buttons facing forward.
Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds.
The DIC will display a message: OFF/ACC TO LEARN.
Press the OFF/ACC portion of the ignition button.
The DIC will display a message: WAIT 10 MINUTES, then it will count down from 10 to 0, one minute at a time.
When the counter reaches 0, DIC will display OFF/ACC TO LEARN.
Repeat steps 5-7 two more times, for a total of 30 minutes.
The DIC will display a message: OFF/ACC TO LEARN.
Press the OFF/ACC portion of the ignition button.
A beep will occur and the DIC will display: READY FOR FOB 1. At this time all previously known key fobs have been erased. When fob 1 is programmed a beep will be heard and the DIC will display a message: READY FOR FOB 2.
Additional key fobs can be programmed by taking fob 1 out of the pocket and inserting fob 2. If desired, up to 4 fobs can be programmed. Once 4 fobs have been learned, the DIC will display a message: MAX FOBS LEARNED, and automatically exit the program mode.
If learning less than 4 key fobs, press the OFF/ACC portion of the ignition button to exit the program mode.
Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation.

Good luck!

2001 XJ 1. Open drivers door
2. Hold the highbeam selector arm towards you
3. Insert ignition key and key to first position (acc)
4. Release the high beam selector and then pull and release the high bean

5. Then press the lock button on each remote to program it in.

Close the doors. Lock the doors using the buttons on the key fob. Use the fob to again unlock the doors. The key should then work the ignition. If this will not work, you will have to tow your vehicle to the dealer and buy a new key and/or fob and have it programmed to the vehicle.

Good luck and hope this help's keep me posted, there are 3 other methods and the 5th method is a tech 2 scan tool that the dealer uses but this should work on your year of cadillac. 

If it is a 2003 model year vehicle follow this procedure. If it doesn't work, you may have the wrong fob which happens all the time.

Sit in vehicle and close all doors.
COMPLETELY insert and remove ignition key more than six times within 10 seconds.
Hazard lights should flash twice.
Turn ignition to ACC position
Press and hold any button on the new key fob hazard lights will flash twice
For a second key fob using the master lock switch, lock and unlock the doors then hold down any button on the second remote until the hazard lamps flash twice.
Then you are done open the door to exit the programming mode.
If the lamps didn't flash when holding down the key fob make sure you have the right key fob, they are different for each car.
