keyless remote
 

I have a xc60 t8 the keyless remote lock and unlock on the handles has stopped working also when starting it says key not found try again it works have put a new battery in key fob no effect.

I have the same issue. Started when I got a message that the battery needs to be replaced , so I replaced both. Didn’t respond. Have read that mostly it is a battery issue. Took it to the dealer, who replaced one, worked once and again no response. Everytime I replace a battery it may work once.
Dealer suggested new FOBs but at a very high cost, and wasn’t sure it will do the job. I ordered replacement FOBs from Ali express. Waiting….
