Srx key fob not working

Asked by GuruVRKM6 Sep 08, 2018 at 09:52 PM about the 2013 Cadillac SRX Premium FWD

Question type: Maintenance & Repair

I placed a new battery in my key fob 2013 Cadillac
SRX because it was appearing to be losing power.   
Now I Cannot get car to start or get the fob to lock
or unlock the car. Got our second key fob out of the
drawer where it has been sitting for years and the
same thing.  Put a fresh battery and still cannot get
a response.  I placed the fob in the slot in the center
console and got it to start after about 10 tries but
could not repeat the success after a few minutes.  
Can it be a fuse? Any suggestions?

Fob needs to be synced to the vehicle: When you are close or in vehicle hold lock and unlock down at the same time for at least 5 seconds, the locks should cycle and the fob should function.

Had a similar situation with my fob not being recognized. However, lights, radio and AC all came on when I pushed Start button, but car would not start. I tried all the standard programming tricks and nothing worked, finally I disconnected the positive terminal of the battery and reconnected it and that worked!

Hello! Any advice.... Remote undetected on 2010 SRK- replaced battery on 2 remotes (tried my unused spare...was undetected too?) Would not work. Followed steps to reprogram. One first try I forgot to hit unlock after, they did not work :(. 2nd try remote did not even start car. 3rd try... remote still undetected but will start car? What should I try next or do I just take to a shop? Thanks for the help!!!

Thanks Guru. I got locked out of my '13 SRX last night. Door handle knobs quit. Synching as you suggested fixed everything.
