keyless with key backup system

Disjoint

Hi all - I have a YALE security system in my house that I proudly installed a few months back. I was looking at getting the wireless door lock https://www.yale.co.uk/en/yale/couk/products/smart-living/smart-door-locks/keyless-smart-door-lock/

However - the reviews are pretty brutal. One key point is that in the event that the battery runs out, you cannot get in the house, or a device malfunction and you cannot get in the house... I would like to have the exact same lock but with a manual old fashioned KEY to open it just in case technology fails us...
Anyone has used a system like that and would recommend? I mainly want to get keyless access so I can let the airbnb and the cleaner into my house without having to resort to some easily breakable keybox on the outside of my property...

I've just taken out of commissions all 3 bathrooms in our house (every single one was installed in an absolutely horrendous way by the previous owner - with one of them draining not in a pipe, but straight into the foundation of my house...) So while I am turning the house upside down I figured I'd give myself another little DIY project with the door handle :rotfl:
