do you have to do it quick to prevent it loosing its code for the car?

I started an exact thread last week, just change it over no need to rush but dont leave it a couple of days, says in the hand book too

I've changed mine, only difficult thing was taking the cover off! I found using the handle of a teaspoon the best tool, put the end through the hole and lever the top forward!

Done it a while ago. Did'nt even think about having to do it quickly! Did'nt have any problem luckily

 

[tommyboy]

[Liam]

the range will get worse

 

[Ross M]

ok. how much are the batteries and where from ? (sorry bout hijack lol)

 

[MikeDX]

I dont think they can lose their memory, hence why they are write once keys and cost £80+ to replace because of the type of flashrom they use I think its a write-once PIC

 

[Liam]

ok. how much are the batteries and where from ? (sorry bout hijack lol)

only a couple of quid each. from any watch type shop...

 

[Ross M]

[V1NNY]

I tried the spoon meathod but no joy, had a go with a large screw driver. Evenually got it off but all the edges are mashed from all thet pulling around. Please note any one trying to get this off, the front plastic button side slides down to the front not up. I found it just to be the battery had come slightly loose so try this first you never know.
