V36 Smart Key stopped working

[Guest]

Hi,

The other day I noticed that I couldn't lock my car with my key, after a few attempts it decided to lock and I didn't think much of it.

When I got home it stopped working completely, luckily I had a spare smart key.

I figured that it needed a new battery , after replacing it today it still doesn't work. Is my other key stuffed, can you get them fixed?

Thanks

Is it just the lock button? Or can you open the boot and use other functions?

None of the buttons are functioning

Maybe you put the NEW battery in upside down.

If not not then open it all up and clean it. If it doesn't work get a new one.

I don't know of anyone who would fix them. 

Might be cheaper to get a new obe

Yeah battery is definitely in the correct way. In terms of cleaning it, it seems like it's fine..
It's ridiculous how expensive they are..
