Key Fob Battery Replacement

[mikej]

Can anyone tell me what battery is fitted to the key fob on a 2001 mk2 2.3 gal 2 button type fob and what is the procedure for replacing it in plain english please , i only have the one key and am a bit worried that if i change the battery incorrectly i may loose any info on it if i do it wrong , do you have to reprogram it after ? :rolleyes: Also if i was to purchase a second hand fob of the same frequency and model is it simple to reprogram this and keep as a spare fob and/or maybe get a new blade cut to go with the fob ?

thanks

The battery is a CR2016. There is no info stored that could be lost during a battery change.

There's information on the forum somewhere on how to programme a new key fob, using your existing key. Probably in the FAQ.

MAKE SURE YOU DO NOT LOSE THE PATS CHIP,small black thingy,or your be fooked.

ebay is a good source for remotes,make sure you get the correct one all the details should be on the side of your own remote,you can also buy blank keys from there.and take the blank to timpsons who can cut it for you for

On a Mk1 fob it uses 2 x CR2016 batteries.

Mk 2 is the same second batteries under what seems to be the base but is in fact a metal spacer, I am guessing its to improve contact between the batteries.
