Can I fit a lock to a hollow door?

Hello all
I have a hollow bedroom door currently, which I would like to add a lock to.
Is this possible to install, or would I need to replace the door for this?
Is there any adjustments I could make to a hollow door to enable a new lock to be fitted?

This should be possible for you – all hollow doors feature an area known as a ‘lock block’ for this purpose.
The ‘lock block’ is featured usually about 70-80cm up from the bottom of the door and should be around 30cm or so in length. (The top of a door will usually indicate which side the lock block is featured on.)
You should be able to adjust the mortice for the lock of your choosing if it requires more space.
If you have any issues with this, feel free to ask further questions on here or perhaps check the door with someone you know with DIY experience.
Good luck with your locks! "

"Look on top of the door, if you are lucky there should be lock printed on the leading edge, there should be a lock block as stated in one of the other answers, you will be able to fit a lock in that."

"Yes, you can. In a solid wooden door it would be hollowed out for the lock body anyway, with the outer frame of the door supporting the fixings, so actually they are easier to fit as less hollowing out is needed. In a hollow door the outer framework of the door is solid and will hold the fixing screws no problem.

Hope this helps!"

"Yes you can fit a lock to this.
If the door is easy to kick in then it may be pointless but if it's to stop a child entering an electrical cupboard, I'd say it's suffice."

most hollow doors have a timber block factory fitted for just this purpose normally about 1m up on the closing side
hope this helps"

"You could fit a night latch to the door or find the lock rail inside the door by tapping down the door until the noise becomes more of a thud and fit a morticed lock to that section.
Alternatively contact your local trusted locksmith and they can go through your options."

"So called hollow doors have a "lock block" inside the door but only usually down edge where the handles fit so it may be possible"

"It would be better to fit a solid wooden door and then install the lock.
With a hollow door one kick and the door will split and you won't be able to close it."
