For the past few days, my car has been telling me that my key fob battery is low. I've not looked yet, but i presume it takes a standard watch type battery of some type? Is there anything I should look out for when changing it? Like, will i lose 'my settings' or anything? I'm rather diappointed for 2 reasons. Firstly, believe it or not, I've never had a keyfob battery run out on me before, and secondly it was supposed to have been replaced 2 months ago, when I had my second service. I could complain, but I guess they will accuse me of switching it with my spare?

I have replaced the batteries with no problems at all. The battery is a watch battery type but i found it difficult to purchase the specific ones from the local supermarkets, I ended up getting a couple off ebay but I am sure somewhere like Halfords will stock them. Probably worthwhile getting a decent make of battery as the first couple i got were not a recognised make didnt last very long.

It is just a matter of taking the back off the fob and popping the old one out and putting a new one back in.

Superglue in the garage locks where the service was supposed to happen will make them pay attention to keys !

I would definately have a word with the garage that did your service :angry:

You might or might not get anything out of it but they would know that they had been rumpled! :nono:

I expect the battery in the smart entry key will get a bit more of a hammering that the standard key, because of the way the smart entry system works. (Don't worry I'm not going into detail :D).

Don't forget your handbook also advises you to try to keep the smart key away (>1m) from other electronic devices (phones, PC, monitors etc), to prolong battery life. Again, not unreasonable, because of the way the thing works.

schm, yes I guess it would drain the battery quicker. However, my 'first' battery lasted 20 odd months and had enough juice in it, that the cars computer did not kick out a low battery warning. Where as my 'second' battery lasted 2-3 months before the messages started :o

Also, is changing the battery in the keyfob a standard service item? I never asked for it, and they did not charge anything extra from the initial quote. I remember seeing the item on my bill, and thought that's good of them :rolleyes:

OK Simon, understood. Just thought I'd mention it. :thumbsup:

The other thing that might sound daft, is make sure the battery is seated into the contacts properly and when changing it, try to keep your fingers off the battery/contact area as much as possible.

Remove the emergency key from the fob first. Remove the battery as follows;

There are no special instructions for initialising the fob.

Thanks anchorman. Saves my looking around. Looks like I need a CR1632.

No probs.

Be sure not to hold the battery on the flats between your fingers. Hold it across the edge...............

........as they hold a tiny charge and you can discharge them in literally a few seconds by holding them on the contact flats.
