Can the battery in this key be changed?

[Stan]

I seems that the little door on this key should open but I do not want to force it.
Any info is welcome

You have to press the button and then the whole unit slides out from the side. The unit then, can be split open carefully just like previous poster cheffy30 says.

Slide open or hinged?

[Northern]

The battery/bulb carrier slides out to the side, then that part splits straight apart

There are two little tabs you need to push in to pop the battery/bulb bit apart.
