Changing the battery in the remote key

On Sun, 04 Apr 2010 10:46:17 +1000, against all advice, something compelled Mark A. Prior, to say:

and unlock it. This key is

working perfectly.

lose it, I would love to

small rectangular notch on

seems as if it is going to

My '04 TT's owner's manual has instructions for this. I imagine your's does as well. Of course, the first thing it says is to have the dealer do it, but it will tell you how.

A 3 handed job it is.

There are 2 main sections of the fob. The top section that holds the key and the bottom that holds the electronics + battery. These need parting and its that small notch that holds the key if you excuse the pun.

Place small screw driver into the notch and gently prise it up only about

Once the bottom is off it is also in 2 sections top and bottom, just a good hard pull and they can be parted.

This is all in the owners manual by the way.

Thank you all for the advice. I have now checked the manual and found the section I had missed the first time around because in my version the words on changing the battery are not in same place as the words on the on operation of the remote key.

Now I have two questions. First, what is the type/designation of the battery? I cannot find any help on that in the manual. Second, is there a time limit within which the battery must be removed and replaced before synchronisation with the vehicle is lost?

Thanks,

Mark

They can vary so you are best check by removing yours.

Also

Sometimes the VW parts people will install the battery(ies) for free if you buy from them. ;-) My remote takes two batteries that are hard to find at most common stores.

I didn't have to do anything special with my A6 key fob. It worked straight away after changing the batteries.

That's probably when putting the new ones in straight after removing the old. It might be different if there were no batteries in it for a while.

The key has been sitting on my desk for ages. I took it apart to confirm which battery, CR2032, and then put the old battery back in and put the battery cover back on. I eventually bought a new battery, yesterday, swapped out the old one and the key immediately became operational. No need to re-synchronise or anything. Makes me very happy, I am now using the old key again and it is clean and tidy because I removed the metal loops there for a key ring; superfluous to my needs.

Thanks for all the guidance.
