Changing battery in Key fob . (HOW TO ?)

I had an instruction sheet, but sadly have mislaid it.  

I know the battery type, it’s a 1620 3V lithium I believe. Have obtained one, a Duracell, dated BB 2021, so am ready to go.

So now I need some kind soul to show me/ guide me to an instruction sheet. I think there is a video somewhere also which might be useful.

TIA

There are video guides for this on You Tube.

Yes you tube “how to install Mazda battery key fob”

I’m pretty sure it’s in the car handbook.

It is, I looked it up last month when I replaced one of mine.

Many thanks for all the helpful replies.
Will have a go this weekend.
Cheers
