Using quality batteries from a reputable source is the solution I've found. There are many fake proprietary brands around from ebay, Amazon etc.

I've just had my first 'Low battery in key fob' warning. Got home, grabbed the other key (which I've never used in 2 years) and tried it out. It ALSO had the same warning. This puzzled me - I would have thought that the spare key would have had more life in it, but I know that both batteries (Panasonic) were fitted to the fobs when new, so perhaps the current drain is the same, regardless of use.

Anyway - I set to work and pulled them both apart: defluffed and cleaned both, and gave a little nudge to the contacts. And remembered to keep the key release button aligned on reassembly.

Went out to the car with one key - no warning. Then took the working key fob back inside the house, and swapped it for the other one - it worked without warning as well.

This has me puzzled. However, I'll pop out and buy a couple of spare batteries just in case.

The last couple of days I've had a puzzling problem with my key fobs. The batteries were replaced about 3 months ago, and I tend to alternate the use of each one.

I've had no 'low battery warning' but using the fob to lock/unlock the car takes 2 or 3 attempts, pressing the buttons quite hard. This would usually indicate a low battery or connection problem with the tactile switches underneath, but a quick visual check doesn't reveal anything obvious. When it does decide to work, it still operates at a decent range. The keyless entry fails to work, but never had a problem once in the car with starting or when travelling. Any ideas anybody?

The only thing I can suggest John is the battery contacts. Make sure they're clean and the battery sits snug in them.

...and both of my keys now need new batteries. Odd how they both went at the same time. No matter - bought two new ones and all is good again.

First thing I tried. However, this morning I went out to test them and they both worked fine, which leads me to suspect the receiver end. The battery wasn't particularly low but it did go on it's weekly trickle charge from the C-TEK overnight. Coincidence?

Changed both mine last week and all OK, Lucky or what.

Both my key fobs are behaving now. Batteries are genuine Varta and have been installed since October.

Just replaced both of my smart key batteries.

Ridiculously easy.

I wonder how much a main dealer would charge?

Do people really take them to dealers to change the battery? It's described in the manual how to do it!

One of them.

They give out free coffee. Figured they give out a free fob battery. I learned.

I'm surprised they don't wear a mask as that is daylight robbery.

It took me no more than 30 seconds per key and the batteries are a couple of quid in Tesco.

I found a couple of Duracell batteries in the bottom of that kitchen drawer all the junk gets kept in.

Freebies as far as I'm concerned.

I find that if the key fob gets really cold, especially this time of year, it can trigger the Smart Key Battery Low warning

Coincidently I've been ooop norrrfff with hard frosts and hey presto my low battery warnings is on
