Hi all.

Can you store second key long term without battery?

Will it reset itself or will it work ok lets say year or two without a battery?

Thanks.

It will be fine my second key has been sat in a box for seven years and still works fine 👍

I asked the dealer a few years ago this very question - predictably they suggested it wouldn't be wise to store it without the battery!

I do know that if the stored key battery expires then a new one pings it back into life without any drama.

Technically a stored and undisturbed (recent style) Kessy fob with the motion detector gizmo shouldn't run down, but they do, about every 12 months.

best to alternate keys, ie use key1 with a new battery for 1 year then use key2 for 1 year with a new battery

the key not in use can sit with the year old battery in it just in case you need it and the key being used always gets a new battery 

this way you spread the wear on the expensive to replace keys
