Srx key fob not working

Take it to the dealer-

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.

guruc4dg8 thank you for your post 2011 cadillac srx tried to put in remanufact key fob would not work then locks would work but wouldnt start with orig pushed and held lock then started omg thank you so much. VHP

OMG!!!! The press unlock & lock buttons at same time did it! Dealer wanted to tow car in.... This worked on my 2018 CT6. Thank you!!!

Thank you SOOOO much for this post - it worked wonderfully on my 2012 SRX!

THANKS SO MUCH for taking the time to post this tip!

Thanx a million GuruC4DG8 ...!! With temperatures reaching 55°C in the summer, i can't afford not to start the car & AC a few mins in advance...

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!

Thank you, GuruC4DG8; you saved me a trip to the dealership and unnecessary expense.

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!!!

The reset worked! You guys are awesome

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

My press check mark to learn remote key not working no beeps just blinks and goes back never says learning active 07 srx

Holding the lock & unlock button down at the same time definitely worked for me. Thanks

You are awesome! Tried for 2 hours to get this remote working right. Ran across this after dealership wanting to tow in, locksmith said couldn’t do it, mechanic came and tried and nothing worked! UNTIL YOUR POST! Thanks a bunch! Really kept my weekend from being ruined!

Reprogrammed my remotes several times and nothing worked until I disconnected and reconnected the vehicle battery. After that, everything worked fine.

I changed the battery and held down the lock and unlock buttons several time then put the remote in the location in the glove box and it started the car but will not do anything else. It;s a 2012 SRX.....any ideas?

I have been dealing with this issue for months now. The dealer replaced (or said they did) the batteries in both fobs as they were both not being detected. Took it for second opinion and we have a new battery in the car now and the shade tree mechanic said that should fix it. It did not. I still have to hold down lock buttons, place in console, burn sage and speak in tongues for it to work. The FOB will sometimes unlock the car or not. The rear door/gate did not recognize having the FOB in my hand. Button on door and button on FOB did not work. I had to use the button in front side door to open the hatch. This is a 2012 SRX.

Tried this...now all of f my windows are rolled down and car still will not start...windows will also not roll up. Help??

I’m having a problem with my key fob syncing to my 2014 Cadillac SRX. I brought it to the Cadillac dealer and they told me I needed to buy new key fobs which I did and they programmed them. Still did not make a difference. They will not stay synced to my car next they told me I had to run it through diagnostics and that came back as a bad module, which they replaced when I went to pick my car up. The remote still did not stay synced with my car. Now they told me I had to replace the brain which I had them do and once again, I went to pick up my car and I got the no remote found alert. I’m not really sure where to go from here. I left my car with the dealer for now for them to figure it out

I recently acquired a 2010 Cadillac SRX SUV .... i replaced the batteries in both remote key fobs. They work, the horn honks, the lights flash, the alarm is set on/off .... but the doors won't lock and unlock ever since i got it back from an inspection at a dealership. He was messing with wires under the car when it was hoisted. The locks worked when I brought it in, were not working when I brought it home. I tried the factory rest, I tried to reprogram, i tried holding the L/UL buttons on the fob down. The lock/unlock buttons on the console don't work either but they never did. And neither does the remote start. Ant ideas on how to fix it?
