Help please.

I need help with my door locks.
My key fob stopped working because I had water ingress and destroyed the ECU under the seat.
After 6 months of having the ECU fitted and all work done and the key gob was working good, it stopped working. I've taken both door locks out and replaced them. This is after my local indi said that the passenger door lock could be the problem.

I still don't have a key fob that locks the doors. I've had a new ecu new key reprogrammed and after all that the key stopped working yet again after only 6 months.

I had a code reading done and there is a fault saying the doors are locked and the garage couldn't get in to the ecu to see if the key had lost it's program. The garage said to change the passenger door lock which I've done but I've also changed the drivers door to double make sure all is ok but still the fob won't work.

These cars and the door locks are driving me nuts.

Can anyone shed any light on what to look at next please. Any ideas at all????
