Manual Door Lock/Unlock Not Working on 2016 ND

Hi All, I had an unfortunate situation recently when, after arriving at my outbound destination, the battery on my key fob died. Why is it these things rarely happen when you’re at home?! Luckily I’d read the owners manual and knew I could still start the car by holding the fob close to the stop/start button so, no worries, I’ll manually lock the car with the hidden key and change the fob battery when I get back home. No luck, the key doesn’t work! I tried the spare when I got home and that doesn’t work either. I wonder how much a Mazda dealer will charge to sort out this “little” problem? Note to self - carry a spare fob battery!

Does the lock turn at all? So the seller supplied the wrong key? Maybe they were accidentally switched between keyfob at some point.
If you bought it from a dealer they should fix that for free.

Thanks for the reply. The lock turns fine in both directions with both keys but has no effect on the door locking mechanism. I doubt they’re the wrong keys otherwise the fob wouldn’t be compatible. One fob is still in pristine condition and has therefore never been used so I suspect it’s an issue with the door lock itself. Most strange. Unfortunately the car is well out of warranty so I’ll have to either get it fixed at my own cost or make sure I’m never without a spare fob battery!

That is a good heads up, thank you. It has never crossed my mind to check that the key does actually work. It is now on my to do list so I don’t find my self in your predicament.

I had the Keyfob Low Battery Warning a little while ago, so went onto Amazon (Other Sellers Available) and ordered 4 replacements - Changed both immediately and kept 2 spares… (CR2025) Cost a little over a pound each and plenty of vids on YouTube that take you through the process of changing them…

Cheers Mad_Malc. I thought my post might prompt a few owners with the keyless entry system to check their keys! I definitely didn’t give it a thought and found out the hard way! :rofl:

Yep they only last about 18 months max, or when you get the green icon on the dash or the locking becomes slow and random.
Definitely worth having a spare battery in the glovebox.
