Locked door?

Question

Any one got any ideas how to open a door with a three lever lock that we have lost the keys for.
I can’t change the lock until I can open it.
I do have access to both sides of the door and it is a new building so I don’t want to make to much mess.
The hinges are not the type with pins either.

Answer 1

First suggestion is just remove the screws and take the lock apart. Take a screwdriver and push the bolt back and open the door.

You can also (if needed) take a 5/16" metal bit and drill the cylinder out of the lock. Just drill about 2" deep right where you stick the key in the lock. Once you drill it you may need to take a hammer and knock the pins loose. You should then be able to turn the knob and open the door.

Answer 2

So many people who have never done this offering advice.
u have 2 options

1- call the locksmith - why would you do that
2 - do what Papercutfaint said.

if there are no screws then you have a twist style holding mech. this type has a ring up against the decorative cover on the inside and outside of the door. This ring will most likely have some sort of key lock or set screw. A small screwdriver or tiny Allen wrench to loss-en. with the key loosened the ring will turn using Channel locks with a cloth over the teeth to prevent scratches. with the inside loose the out side will loss-en as well. with both rings loose you'll have enough play in the whole unit to find a hole which lets you see inside the tube. in there you find a small stiff wire holding the inner and outer parts together. use a small screwdriver to free the wire and the door knob will fall into two parts. At this point the door is unlocked however the bolt is still in place. Inside the hole in the door you will see a square hole somewhere on the mech. Use something that will fit through that hole and move that hole towards the hinges. (you may have to wiggle the door)

Mr costalot might just cost you a lot !...providing you have loose stops on the frame then you can remove these ..if not you will ruin the frame ..if you can get the frame stops off there is no guarantee that you can saw through it with a hacksaw as most locks are case hardened and will not cut with a hacksaw ..you could try to drill holes into the side of door frame where the lock keep is and then with a blade cut the piece of keep that locates the lock ..you will need to repair frame but you can put architrave to hide it

Answer 4

call a lock smith. if you don't want to damage the door.
or try picking it yourself....... goodluck


this is a note for plane jane...
a 3 lever lock, similar to a 5 lever security lock. mostly found in mortise locks. have been used for hundreds of years, denotes the number of levers that need to be turned to unlock the door..

Answer 5

I take it this is the dead lock type of lock therefore you will have to cut the bolt (the bit that sticks out ) you may have to remove the door jam to do this
pry this off gently with a flat bar or large chisel then using a hacksaw blade inserted between the door and frame just saw though the bolt take it slow
this will cause some minor damage to paint that can be sanded down and repaired with ease
Please try all the keys you have first as most 3 leavers are not that key fussy (non security rated )

Answer 6

Make sure the locksmith is LICENSED and BONDED. Have him/her open the door and change the lock.

By the way: what's a 3-lever lock? I've changed hundreds of locks and even had to use various methods (science content, therefore no specifics) to remove locks that were broken or had no keys...but I don't know the term '3-lever lock.'

Answer 8

from inside the room use a fine mettle blade on an electric grinder to cut through the lock be careful you dont damage the door/jamb.

Answer 9

Call a locksmith to pick the lock or use a master key.

Answer 10

locksmith - but it will cost or maybe the people you have bought from have a set of keys - this would be worrying though.
