No problem.
One thing not considered so far in our musings is the electric connection between door and van - it’s the sprung loaded multi pin that connects with a static receiver plate. Might be worth giving the brass surfaces a clean and check the power and earth for adequate voltage. If the latch motor is getting inadequate voltage due to corrosion resistance it could prevent the unlocking element of the latch….worth a check before parting with your hard earned.
