My doors stop locking on my 2016 Land Rover LR4 on both my key fobs. Anyone any ideals of what it could be? It act like it’s locking but it’s not .

 

It could be a simple as a fob was left inside, one of the doors is not properly closed or, a door lock module is toast.
Actually, the locking solution is quite extensive now. Please see the excerpt from the workshop manual...
