Fear of the back door

To all the users of this site, my back is
The same thing that happened around 18 months ago—the passenger door won't open—has happened again.
Is this possible for a failed mot test?

My door was severely dented, but the mot assured me that it would not fail as long as it could be opened and shut correctly.

Not going to open from the inside, outside, or both, will it?
I don't mind if it won't open from the inside.
If it won't open from the outside, I'd say it's a bust. That is, unless by some stroke of luck they open it from the other side to check the seat belts and everything!
The n/s/r door on an old car wouldn't open for some reason—the control rod link had come loose, but I didn't notice until the MOT because I hadn't used that door in a long time! It is unbelievable to me that it is any laxer now.

Yes, both inside and outside the car, to answer your second question.
I made the door stop doing that 18 months ago.
The problem is that I have no idea how I accomplished it; after all, no human memory is perfect.
Fixing central locking is a real pain in the neck, I get it.
Is the estimated repair cost in the hundreds?

Since it is dependent on the nature of the problem, whether you choose new or used parts, the person performing the repair, and so on, I am unable to provide any advice. In any case, you won't know for sure until you open the door and take a good look.

However, if you are unsure of the vehicle's overall condition, I recommend taking it in for a MOT regardless to find out what it fails on, especially if the inspection is imminent. It would be a waste of money to fix the door if it turns out to need far more expensive repairs and you end up selling the automobile. The obvious caveat is that I don't know anything about the car or your situation, other than the fact that it is a Mark 1 Focus.

Honestly, I'm not convinced that 18 months is considered recent. Given that MOTs are scheduled annually, you would have discovered the problem during that period. However, has the automobile been taken off the road?
The item is considered a failure if it does not open from both sides, though.

If this is the consequence of your actions, we will remain in the dark because we do not know what you did, whether intentional or not.
Was the door disabled on purpose or did you accidentally turn it off?
If the issue is with the door itself, removing the door card—which may be difficult if the door is closed—will be necessary to fix the problem.
As an example, I can't do it on my Mk4 Mondeo since the six screws that surround the door card can only be accessed while the door is open.

If you can't recall whether you unplugged a rod or something, you might have to rely on your memory.
