What are the best security locks for an external wooden door

I am moving into a new flat and I want to improve the lock security on the front door. At the moment it only has a night latch, so I want to change this for a new one that complies with BS3621 and then add a deadlock. I would appreciate any advise on what are the best locks to get. Is a euro cylinder lock more secure than a 5 lever mortise deadlock? Or is there little difference?

How to replace lockable door handles with normal ones?

I have two internal door handles I want to replace. One is a backplate handle with a thumbturn lock built in. Is it OK just to replace this with a normal rose door handle, no lock?

The other has a rose with a separate thumbturn lock. It has also lost its rose cover. I have managed to remove the lock cylinder, but can't seem to get out the rest of the lockset (right term?) from the edge of the door - I think one of the screws in the face plate (right term?) is bent. I haven't yet tried removing the door handle. Would it be possible just to replace the handle and fill in the cylinder lock hole, that goes through the door from front to back??

Door lock seems like it’s grinding

Hi,I’ve just had a front door fitted and when you turn the key it grates as it’s turned ,I’ve mentioned this to the company and told them that my other door locks don’t do this .They have said it’s a different mechanism to other doors but as far as the mechanism goes it looks the same locking system but as far as I knew the key just turns the barrel lock locking the mechanism in position,in my opinion it is the barrel lock which is not accurate rather than anything to do with the mechanism it’s like the key itself is making the noise as if it’s not accurate the friction noise is felt by the key ,it’s not difficult to turn a slight resistance ,am I correct expecting the key to turn smoothly or is this classed as acceptable please ?what would cause a key seeming gritty when turning it please and do I have grounds to as for the barrel to be changed thanks in advance Kind regards Pete

ERA Dead Lock Won't Lock / Unlock

I have an ERA dead lock fitted on my flat door and one day it suddenly stopped working, and I was locked out.

I was able to turn the key all the way to the very end as usual, but the dead bolt just refused to move. A locksmith came and pull the cylinder out a bit and suddenly it worked! He then kindly changed one of the long screws on the faceplate and told me it was caused by a misalignment.

However, I'm having the same problem again after 3 months, luckily this time, the dead bolt is stuck at 'open' position.

Please, anyone has any idea how to fix it? What is causing the problem? And how to prevent it from happening again?

Thanks very much.

Door knob/handle combination


We are looking to install a new lock and handles on an exterior (back) door.

We’ve been told to get a 76mm 5 lever sash mortice lock with a BS stamp. We’ve found a Yale lock that matches what we need, but we’re now looking for handles, and this is where the problem lies.

On the exterior side or the door, we’d like to have a door knob that doesn’t turn or open the lock. This way, anyone from outside the house cannot enter without a key. On the interior side, we’d like to have a functioning door handle, that doesn’t require a key to open - but we can open to exit.

To sum up - it should be possible to just close the door shut from the outside without locking with a key, so that it is not possible to re-enter without a key; but from the inside there would be a handle to open the door if not locked.

Does anyone know how this works, and what we need to get to answer our problem?

Many thanks!

Victorian Internal Doors


Anyone know if its possible to get keys to fit long lost originals for Victorian internal doors ?


Hi, we have a upvc double glazed door with a multi point lock which opens into the garden. The door doesn't appear to be closing properly which means the handle will not move upwards in order to lock it. It needs to be slammed very hard and whilst pulling, the handle needs to be forced upwards in order for it to be locked. Not sure who to contact so can anybody advise me please? Many thanks.

I have oiled all parts of lock inside and out to no avail.
