I have the same issue too.
watched a youtube video, and some comments have the same issue, but no solution was found. frustrating.

 

I think there is a recess in the floor of the center console place it next to that see if that works much better

 

putting Fob into center console slot to start car working just fine.. I tried all three keys with new batteries. very strange.

 

So its resolved?

 

No.. it still the same. no message popped on DIC

 

try a different master remote? do NOT have 2 masters with you at same time & keep new one well away till prompted for it

 

try a different master remote? do NOT have 2 masters with you at same time

Oh, I brought 2 master and 1 Valet with me.
I will try with only one.

 

keep FAR away and the master in console only - not on a key ring, take the emergency key out of the remote

 

also think about this.....

Thank you for this.

unfortunately, I tried all and didn't work out.

 

well ......i suppose last attempt is to reset the car.... disconnect the black battery cable for 10 minutes, you may have to re-lean windows and a few other things......if no joy..then the dealer will be happy to see you as he has a boat payment to make LOL......

 

I believe the problem is due to you only have 1 working remote. You NEED 2 good remotes to program a 3rd one. If not, you must "Relearn" ALL the remotes (see procedure B). Try this procedure, which will require 30 to 35 mins. Watch the video for clarity. How To Program A Cadillac SRX Smart Key Remote Fob 2010 - 2016 - YouTube

GM Smart Key Remote Keyless Entry (RKE) Programming:

(A) Programming with 2 Recognized Transmitters or key fobs.
A new RKE transmitter can be programmed to the vehicle when there are 2 recognized RKE transmitters. To program the vehicle must be off, and all of the RKE transmitters, both currently recognized and new, must be with you.

1. Place the recognized RKE transmitters into the storage bin with the lock icon.
2. Remove the key lock cylinder cap.
3. Insert the vehicle key of the new RKE transmitter into the key lock cylinder located on the outside of the driver door and turn the key counterclockwise to the unlock position five times within 10 seconds. The DIC displays READY FOR REMOTE #3, 4 or 5.
4. Place the new RKE transmitter into the storage bin with the buttons facing up.
5. Press ENGINE START/STOP. When the RKE transmitter is learned, the DIC will show that it is ready to program the next transmitter.
6. Remove the RKE transmitter from the storage bin and press UNLOCK. To program additional RKE transmitters, repeat Steps 3–5.When all additional RKE transmitters are programmed, press and hold ENGINE START/STOP for 12 seconds to exit programming mode.
7. Put the key back into the transmitter.

(B) Programming without a Recognized Transmitter or only 1 good key fob.
If no currently recognized RKE transmitters are available, follow this procedure to program up to eight RKE transmitters. This procedure will take approximately 30 minutes to complete. The vehicle must be off, and all of the RKE transmitters you wish to program must be in the vehicle! Your dash or DIC may go dark or blank out during this procedure, which is completely normal. Simply open and close the driver's door to refresh the dash display.

1. Remove the key lock cylinder cap from drivers door.
2. Insert the vehicle key of the RKE transmitter into the key lock cylinder located on the outside of the driver door and turn the key to the unlock position, counterclockwise, 5 times within 10 seconds. The DIC displays REMOTE LEARN PENDING, PLEASE WAIT.
3. Wait for 10 minutes until the DIC displays PRESS ENGINE START BUTTON TO LEARN and then press the ENGINE START/STOP button. The DIC will again display "REMOTE LEARN PENDING, PLEASE WAIT".
4. Repeat Step 2 two additional times. After the third time (3 x 10 = 30 mins), all previously known RKE transmitters will NO longer work with the vehicle. The remaining RKE transmitters can be relearned during the next steps. The DIC should now display READY FOR REMOTE # 1.
5. Place the new or next RKE transmitter into the storage bin with the buttons facing up.
6. Press ENGINE START/STOP. When the RKE transmitter is learned, the DIC will show that it is ready to program the next transmitter. READY FOR REMOTE #2, etc. etc.
7. Remove the RKE transmitter from the storage bin and press UNLOCK. To program additional RKE transmitters, repeat Steps 5–6.
8. When all additional RKE transmitters are programmed, press and hold ENGINE START/STOP for 12 seconds to exit programming mode.
9. Remove the key from the exterior door and put it back into the transmitter. Replace the key lock cylinder cap

 

I've added two fobs. The first go around the DIC went dark on me. Procedure still worked, but the car had to sit awhile. At first it seemed like a fail. A half hour later it was working. Go figure. The 2nd time, thinking time is of the essence, I did it as fast as I could and got it done before the DIC timed out. No issues and it literally took about 60 seconds start to finish. Also that first fob never worked quite right and only lasted a year. When buying aftermarket, all fobs are not created equal.
