Thanks Key Fob Rob. That was spot on. I had bought a 2012 MDX back in Feb 2020 (right before Covid exploded). Apparently, the batteries in the key fobs had never been replaced since the car was brand new. So, even though it would unlock the doors and tailgate, it was hit and miss on the driver settings, especially moving the steering column back into position. I checked the old battery with my tester and it was way into the red. So far 🤞 the new battery seems to have corrected that behavior. My theory is it takes minimal power to open and close the locks, but once you insert the key to transmit which user you are takes much more, and the battery is temporarily drained at this point. Sorry to make this so long, but I have seen so many MDX owners complain about the steering column issue.

I was stumped on my own where you have it at your 35 second mark. Thank you for showing how to pry along the edges to get the battery exposed.

Ugh thank you so much your video saved my life!!! Kept having the car alarm go off due to a low/faulty battery in the middle of the night!

Great video. I changed mt battery but my fob will only lock not un lock. Must be something else wrong with the fob.

KFR! What a beauty DIY... helped me tonnes. Do you have any advice for the same switchblade style key, but the key doesnt sit flush inside the housing anymore?

It worked for about an hour, and now it's reverting to the original issue. My alarm is going off at random. The only time my alarm goes off is when I'm at home. It doesn't go off when I'm away from my house.
