It's just a cr 2022 battery easily done by yourself.

Both my (keyless) key fobs showed needing a replacement battery on the MFD after just 1 year. Seems the keyless fobs are very active all the time regardless of whether they are both used, so get 2 batteries at least

I think mine are on there way. Had a no key detected message a few times and doesn't seem to react as quick. Car is now 14 months

I changed mine at Christmas. Car was 18 months old at that stage and it has keyless. I suspect the keyless system is a bit harder on the batteries.

Same with mine. 18 months old and on the key I use all the time, got the warning that the battery needed changing. Went to my local dealership (who supplied the car), to buy the battery and ask how easy it was to change, and they did it for me there and then FOC (took about 2 minutes).

My car is only a couple months short of two years now and not had any issues to date with the keyfob. Of couse it will be sods law that something happens in the next few days

Just had low key battery message for first time after 18 months and 67k miles. Will see how long it still lasts and just keep a spare CR2025 in glove box for when it dies (they are only 1.50£ on ebay for a swiss made Renata CR2025).

Just had a key fob battery warning light on the dash. Quite surprised as the car is only 19 months old and done 19,000 miles. Just goes to show you how much the KESSY system talks to the key compared to standard remote central locking. Must drain the battery (which isn't a tiny one either).

I swapped the battery with the spare key. Can't risk the key dying and not being able to start the car
