Had my 2014 GTD about a month. only came with 1 key, which I was going to get round to getting a second spare, but have just had `Replace Key Battery!` come up on the dash display!
Anyone know how long I`ve got to replace it??
Thanks.

I'd be wondering about the whereabouts of the second key. Was the car bought through a dealer/garage or privately?
That was my first thought too.

I’d be arranging to get a second key and having the keys reprogrammed, so if whoever has the missing key knows the whereabouts of the OP’s car, the key in their possession won’t work.

Had one of mine just die yesterday with no dash warning at all. Had to use the other set to use the car as it's keyless. Put new battery in dead set and now working fine. Car is two years old next month.

A 2032 battery will fit as well. It is only 0.7mm thicker and fits no problem. It should also last longer than a 2025 and the Panasonic 2032 are very cheap for a pack from b&m.

I’m guessing you replaced it weeks ago!

I had the same message on my wife’s GTI and forgot about it, about a week later I was stranded and my daughter had to drive out to me with the spare fob. It’s crazy the whole car shuts down if the tiny little £0.99p battery goes flat!
I changed batteries in both fobs. The car was only about 18 months old. I’ve got a keyless entry M3 which is coming up 4 years old and never put a battery in it.

@s1monc; it probably wasn’t necessary to get your daughter to bring you your spare key. If your key fob battery dies without warning, you can open the driver’s door by prising off the rear section of the driver’s door handle (being careful not to damage the paintwork!) to reveal a key hole and then use the key blade to unlock the car.

If you’ve got keyless start, the YouTube video at the link above also shows how to start the car when the key fob battery is dead. It’s s USA car in the video, but the opening and starting procedure will be the same for a UK Golf.
