C-class rear door won't lock remote doesn't work
I've replaced the car battery and the remote batteries and the problem is 2 issues if I leave the car for a period of time then the remote doesn't open any doors no lights flash nothing the light on the remote flashes.
If I get out of the car and immediately push the door lock all the lights flash and all locks except for the rear drivers passenger door and will reopen again as long as I don't leave the car for too long
The other issue is the rear passenger door drivers side doesn't lock from the outside and occasionally will lock if you push the lock door button on the center dash. When central locking all doors. Very weird.
Any ideas appreciated

Only way to properly diagnose a problem like this is to gain access of a DAS machine. Your local dealership has many of them. They will perform a short test and will look for any fault codes in the central locking module as well as the anti theft module. The DAS machine will tell either you or the technician exactly what to replace,test or adjust. It is very hard to diagnose a problem like this over a fourm without any sort of fault code.
