2 Years In and Main Remote Battery Died This Morning

**BenT** · 12-03-2021, 02:34 AM

I put a new battery in my remote but the light doesn't come on when I press the buttons. Tried the old battery and it worked. Tested the new battery and it had 3.29V so it's OK, but tried it in the remote and still not working.

Turn the battery over so that the writing is visible when its in there. Or its the wrong battery Like a 2025 which is thinner than a 2032

The original was a 2025, and that's what I replaced it with. Made sure the writing was face up. Sadly not working so I'll see what the dealer says on Monday.

Did you try more than one in case it was a dud or check you havent pushed the underneath contact down when you took it out, but seeing as the old one still works possibly not.

The old one's not working now, but the other key is fine so I'll open both and inspect to see if somethings bent, and see if the other battery works.

2 year mark and my wife's keyfob died even though she uses my car only once a week.

Seems strange for a keyfob to die after being used once a week for 2 yrs

My last SUV (non VW) lasted almost 5 yrs of daily use. Go figure.

Keyless entry pulses the keys everytime you unlock or lock the car.

Also when you start the car you'll notice the red light on the key flash.

If your wife's key is within the cars proximity in a bag or drawer this is activating everytime you trigger any of the above.

A new battery is all of $5 though so it's not a massive inconvenience is it?

Even stranger is the fact that my spare remote which has only been used about 5 times in 2 years needed a new battery this month.

I had taken my car to the dealers on Sunday for a Monday service and forgot to put the oil in the boot. Had put the remote in their drop in key hole. Went home and got oil, went back and opened boot with spare remote. All good. After car came home i grabbed spare remote and tried to open car. Wouldnt do it
So went and got usual one, unlocked it and took it away . Car wouldnt start with spare right up against steering column. New battery an all was good. How lucky was I at the dealers LOL

You got ripped, they are $5 at Kmart

I will buy a pack of 2025's tomorrow and see how it goes

It was lucky the wife was at home when she used her keyfob as she would have had not idea how to access the keyhole in the door handle.

Even if she was shown how, she most likely would have scratched the car with the key if she followed this video.
Compared to my previous SUV, the emergency access key slot is poorly designed by VW as you are most likely to scratch the car using your key to pop open the cover as per the video below.
