Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Was this a New (unused/ unprogrammed) FOB?
With a "fully charged Battery", you followed these instructions :
Replacing Keys (Without SPS)
Note:This procedure will unlearn all previously learned keys. All keys that are to be programmed must be with the vehicle.This procedure will take approximately 30 minutes to complete.A total of 8 keys maybe be learned to a single vehicle.This procedure will only learn the vehicle key information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).This procedure may be used with or without existing learned keys being present. If existing keys are present, keep the keys away from the vicinity of the vehicle. Failure to keep learned keys away from the vehicle will result in the learn changing to the Adding Keys procedure.The keys to be learned must duplicate the mechanical cut of the current key.Insert the mechanical key of the new transmitter into the key lock cylinder located on the outside of the driver door and turn the key to the unlock position five times within ten seconds. The Driver Information Center (DIC) will display Remote Learn Pending, Please Wait.After ten minutes, the DIC will display Press Engine Start Button To Learn. Press the ignition mode switch. The DIC will again display Remote Learn Pending, Please Wait.Repeat Step 2 two additional times, for a total of thirty minutes. All previously known keys have now been unlearned. Remaining keys can be relearned during the next steps. The DIC display will now display Ready For Remote # 1.Note: The key pocket is located inside the center console storage area. The key must be placed flat in the pocket with the buttons facing up and the key ring at the rear. If a large key ring prevents the key from laying flat in the pocket, remove the key ring and place the key in the pocket. Failure to position the key flat in the pocket will result in an inability to program.
Place the new key into the key pocket.Press the ignition mode switch. When the key is learned the DIC will indicate that it is ready to program the next key.Remove the key from the key pocket and press the unlock button. To program additional transmitters, repeat Steps 4 through 6.When all additional transmitters are programmed, press and hold the ignition mode switch for 5 seconds to exit programming mode.
I was enquiring if you used that method...........Problem with this year Cadillac, is once the FOBs are erased, you cannot "Program" a Used FOB to the vehicle using this methodSo these would be considered UsedUse of GM Dealer Scan Tool would be needed to Programapprx 1 hour labor
IF you are sure the vehicle is not in Security mode, yes you should be able to Program another using the Programming Method
It may be cheaper for tow, as the Remote with Remote Start is apprx $192.00 & the one without is apprx $140.00
Did you have any other questions?I see you have viewed my reply but have not selected a rating.Rating does not incur any additional costs, it simply allows me to be compensated for my time here.It also does not close the question, you can follow up at any time.Thank you.
