Earlier posts in this thread have suggested Duracell aren't suitable and recommended Panasonics instead. Which are yours?

The new keys should turn off if not moved for 5 minutes, prolonging the batteries. Are yours being moved a lot, or the buttons pushed inadvertently?

My wife’s KESSY keyfob battery also failed yesterday. She said she didn’t remember seeing any kind of low battery warning on the dashboard.
I swapped the battery for a cheapo one which I had at home, but still no luck. I therefore tried testing both batteries on the battery tester which I had at home. Both of them were showing a good level. I’m not sure how many volts, as it wasn’t a voltmeter. I didn’t get a red lit LED on the keyfob with either of them when I pressed a button.
So then I bought a Panasonic battery, put it in the keyfob, and it worked first time, without even having to re-sync it. So I guess it’s best to stay clear of the cheapo Poundland coincell battery packs, and stick with Panasonic.

Just like the washer "top up" that you pay for on a dealer service, changing the key fob battery will turn into something the dealer does every time (and charges you for the pleasure).

Had same problem yesterday, battery failure, no warning. Paradoxically my wife’s battery ran out only last week with a warning. Situation saved by wife taking an Uber to bring her key to the car. Now have installed an Energizer in my fob. Learning for me and recommendation to others, always carry a spare battery in the car…the door can always be opened manually.

Read the manual regarding opening the door using the key in the lock and then starting the car by pressing the the starter button with the key fob.

I tried that and had to get a man from Skoda Ensurance to come and do it for me as the key just turned in the lock barrel. To make it work, the key has to be pushed and held in VERY firmly while it is turned (I don't know if that is a general problem or just my car). Starting the car with the key against the start button worked, but took several attempts while the alarm was sounding.

I would also recommend caution regarding the selection of batteries for the fob. I have tried Duracells and Energisers, both failed early, without warning (the second Duracell after only a couple of weeks). So far the Panasonic battery, that my dealer and several people on other Skoda forums, recommended has been fine for 10 months. I will replace the batteries in all 4 Skoda keys in the house at the end of the year. The cost is small compared to the hassle of being locked out on a freezing wet night 30 miles from home.
