Battery has done well to last 2.5 years

My Fiat is 14 years old this month.  The key fob is still on its original battery.

Batteries were much better quality in The Olden Days

More likely the car has keyless theft installed which kills batteries in a much shorter time as they are working much harder.

Also, don't get the cheap 8 for a £1 ones as they will only last 18 months, get a decent quality one and it will last another 2.5-3 years.

To echo the advice in that video, confirm which battery is required.

Probably CR2032, but some remotes use a CR2016, e.g. Toyota.

I am with Nissan on personal contract hire. Had the car about 2.5 years and I pay monthly (includes yearly servce cost). My car key is saying battery is low.

Nissan are telling me I have to pay for replacement although I asked them if it would not be covered by warranty. 

Could be a CR2025 battery not usually available from Poundland try Amazon

You don't have to use the remote

My car wonlt start if the battery is done. Tells me the key is not recognised.

I've just done this. Two year old Nissan Leaf with keyless start. Got a message on the dash saying that the key battery was low. Followed a youtube video for a similar Nissan fob which said it would be a CR2032, but it turned out to be a CR2025. Fortunately I had two in the house that I had bought by mistake some time ago. It worked fine after changing it. 

I had the car serviced about 3 weeks ago and it was my key we gave them. In the old days garages used to replace batteries in remotes at service time - but I suppose everything is now chargeable separately.
