It does seem, from varios posts, that the batteries last just over 2 years irrespective of how they are used. Also the warnings seem to be hit and miss.

I would suggest that they are changed every 24 months even if they seem to be OK.

It very easy to do. Open the key and put something like a big screwdriver blade or even the blunt end of a dinner knife or fork in the slot where the key rests and twist. Don’t try and do it with your fingers as the plastic edges are sharp and you may cut yourself. The cover will pop off easily. There is a very small slot, just big enough for a very small screwdriver, in the area surrounding the battery. Use that to release the battery. Inserting the new one is easy, just pop it in and press into place.

Yeah don't get Morrisons own brand ones, I did, left me scratching my head before seeing this thread.
Tested them with a volt meter and they were 3v so I think its about the current they give aswell as volts.
swapped for Duracell and worked fine.

Seems I was a lucky one. stopped working with no warning. Changed the battery for a proper branded one, heart in mouth pressed the button. Never been so relived to unlock a car with a remote in my life.

Same thing happened to me, KESSY not working reliably for a couple of weeks then one day car wouldn't unlock even with unlock button. No dash warning. Spare key worked but Please replace key battery message popped up when I started, no chime, I even missed it the first time because it was only displayed very briefly upon engine start. Replaced both batteries and all is good. Looks like the dash warning is unreliable and easily missed when it actually works. As useless as the driver alert assist.

Perhaps you're using crap batteries?

Good morning everyone.
I have previously responded to a similar post on this subject.
I have had my Ateca for 18 months and have had to change the key fob battery 3 times. Each time I replace the previous battery with a Duracell one. My key fob merely opens the doors remotely (or the hatch) it is not a kessy system. However, to fold in the wing mirrors every time I park, I have to hold the remote button in for 3 seconds. I believe that is what is causing the reduced lifetime of the batteries.
With previous cars I have had, the batteries have lasted 2 years or more.
I am not that bothered about having to change them so often as even Duracell batteries can be bought on ebay or the like for about £1 each and it takes 30 sec to change the battery. I keep spare ones in the glove compartment and one in my wallet.
