Do you carry the remote around in your pocket with other stuff Have known of things in pockets to get turned on flattening the battery for no reason by being pushed aginst something depressing the button.
Mine arent keyless but the remote in the Passat lasted 5 years and the Polo one is 6 1/2 years old and hasnt been replaced.
Update: The (Panasonic) 2032 battery hasn't worked out - not even 3 weeks since installing it, I got the 'replace keyfob battery' message in MFD.
Swapped it out for a 2025. See how this goes...
Ralfi: I had a PM from a Vortex colleague a few months ago who had a similar problem.
Of course, the underlying problem could be battery drain (as the error message suggests), but it's unlikely (IMO) that replacing the battery will a long term solution (because you are tackling the "effect", not the "cause") - given that you have already tried this before.
Anyhow, the problem for my Vortex colleague was real strange - it seems that the issue was caused by a security camera that he retrofitted to the car and that he had powered by tapping into a particular fuse on the car (piggy-back fuse). When he re-routed the fuse to the position for the power socket - bingo, the problem was solved. Go figure!!!
Now, I'm not suggesting that yours is the same problem, but examples like this show how complex these issues can be - especially where components like the immobiliser coil and the insert in the instrument panel is involved (IMO).
So - just as an easy try - why not see what happens with the second key? does using the second key for a period of time result in the same error?
Also - have you actually checked the voltage in the "supposedly" flat battery?
Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is in the forum proper. That way you get the benefit of the wider expertise of other forum members! Thank you.

Both use the CR2025
Nah the key has its own pocket, & I'm always checking to see if it's (a) there & (b) not having pressure applied to it.

Thanks again Don.
Just checked the voltages. Both the 2025 & 2032 had a touch over 3v. The 2032 was slightly higher. Though I'm not sure if this basic test is enough to say it's still in good condition?
I've now put the 2032 into the other keyfob to see how long it lasts.
One thing I've noticed is that the battery cover of this keyfob closes flush with the rest of the case whilst the 2032 is inside. The other keyfob doesn't close as flush even with the thinner 2025 currently inside. This slight rise of the battery cover may or may not have occurred when I inserted the 2035 in there. I don't think so though, as the other keyfob looks fine with the bigger battery inside.
