Very and extremely tired and worn out

I have bought my Renault Clio in 2021 After a year and I have to change my car keys This were not dropped(chipped) or wet.. Within a period of 5 months I have changed the lock key.. The problem started again mind you the new key has not even reach 6 month and it's stated giving me a problem already. I know this tons of crd keys which are not working and they costing a fortune. Car never missed a service date yet both the service team. And lock man can not detect a problem on the car? How long will I keep on by a new key that won't last meja a life time?
