fitting a lock to an internal cheapo door

[Unobtainable]

Is it possible to fit a lock (key hole with key) to one of those ‘no paint’ internal doors? Would I need to get a proper wooden door?

yes

if it is a £30 hollow door, made of air with a thin coating of hardboard or ply, there is usually a block of wood inside, about half way up, on one edge of the door.

If you get out your steps and look at the top of the door, the factory will have stamped something on the top edge to say where it is.

A lock fitted to a door made of air will not keep out a burglar, but will stop it blowing open in moderate winds.

You can also get special bathroom locks, which are also suitable for bedrooms, and can be operated with a turnbutton from the inside.

"Q: Where is the lock block position on a Premdor door?

A: Standard Core doors have a single lock block. The side of the door that the lock block is situated is indicated on the top of the door. On the veneered doors, the lock block is positioned centrally. On moulded doors, the top of the lock block is located 880mm from the top of the door.

The lock block is 360mm long by 80mm deep (+ / - 15mm).

The Semi Solid Core door (moulded only) has a full length lock block on both sides of the door.

Safe 'N' Sound (moulded only), Fireshield FD30 and Firemaster FD60 doors are solid core options and therefore, there is no lock block."

Fantastic! Appreciate all the help. PigletJohn I thought you only did plumbing!
