Remote key stopped working

The second battery was probably almost out of charge before you started using it, and using it consumed what little charge was left. As Idle says, it is easier/more convenient to replace them before they go flat.

I've read of VWs with keyless entry needing new batteries after only 12 - 18 months. My Octavia & T5 batteries seem to last over 5 years (but neither gets used every day).

Mine is keyless and they lasted just short of 2 years. Similar to yourself, my Yeti's were at 5 years and still going strong when I sold it.

Same for me rooboy
I replaced my battery in the key some 3 months ago
Not a very long life i suppose keyless entry and starting place a extra drain on it

I've just checked and replaced the batteries in my remotes:

Golf R (keyless) batteries had 20% charge 25 months after being built

Octavia & Transporter batteries all had 60% charge after more than 5 years.

To check battery push the lock or unlock button of the remote while engine running. If battery getting low you will get a message in MFD to the effect of “check remote battery”. This on a 2018 model with keyless.

My Golf R key battery went flat after just short of two years. Pretty easy to change, batteries available from supermarket. No recoding or anything required
