Are they not all CR2032?

 

Errr - can't you open yours and look see?

 

Yeap I will do, but it's odd, I was getting a Low Battery Message in remote from the car on Saturday. Drove the car on sunday with the Key in the slot under the steering.
Drove the car last night and no message.

 

battery output is affected by temperature. If you've had the message once, change em.

Mook

 

What sometimes happens is you've been pressing a button on it, in your pocket, for a while and the volts are depleted. When it's had a rest, it recovers.

Still change it, CR2032 :thumbsup:

 

Thank you gents, awaiting replacement batteries.

 

change it when you get the warning as it might trip up the immobiliser/alarm/tracker

I had to take the main battery off for a day to reset it

 

just for the record you can get the batteries from behind the counter at most petrol stations, I keep one in the glovebox just in case.

 

And I buy batteries in a box of thousand
(a Car locksmith) as a rule of thumb for batteries and especially the coin type batteries

If it is a big brand name they may not be as good as a generic brand
Maxcell or Sun Cell are pretty good,

I have a LOT of customers telling me that they replaced it with a Duracell or
similar - and they die within a week - especially proximity keys.

 

Just changed the batteries in both my fobs (MY20)...
After changing the each battery the fobs didn't work
However, putting the fob in key-fob-battery-flat slot (low down on LHS of steering wheel) and pressing the start button to power on the car, then waiting ~5 seconds, the car and the fobs seem to have re-paired themselves - happy days.
It did take a couple of attempts, but I now have 2 working fobs again.

 

I had a weird one a couple of months ago. One fob would not work (as I assume a flat battery as you would). If I then used the other fob, it would work as expected, but then the 1st one would start working. How odd !!

Anyway, I popped a new battery in the 1st and it's been fine ever since.
