Questions for the locksmiths out there. Problem with double glazed front door.?

Question

If the key sometimes spins in the lock without actually unlocking the door is it the barrel that is likely to be worn or the mechanism in the door itself?

If it's the barrel then it's simple enough to replace. If it's the door then I've no idea...

The barrel is Corbin and looks like the one shown in this link:

I'm going to replace the barrel and see if that fixes it. I've already taken the existing one out and it looks okay, but for a tenner I might as well give it a try.

Cheers for all the answers.

Answer 1

It is probably the Euro cylinder that is worn out. You can remove this with one screw in the opening edge of the door (remove screw and turn key untill cylinder slides out) then either take the old lock as a pattern or measure it (for example 30/10/40 means 30mm on one side/10mm for locking tab/40mm on other side) Most hardware shops should supply a reasonable cylinder for about ten pounds. I would advise paying about £15 to get a decent one (ERA, yale or union for example). While you are there be cheeky and ask for a couple of extra keys. When anybody buys a lock from me I always ask if they want more keys, if they want ten I make more money but if they only want a couple then I cut them for free, the blanks only cost about 5 pence each.

Answer 2

Is what you are calling the "barrel" the part where the key goes in?. If so and it turns when you put the key in and doesn't turn without the key then that part is working fine, that's all it does. What has probably happened is the piece attached to the part that spins has broken or come off. Sometimes it is like a tail sticking straight out the back and other times it will be a small tab that sticks up flush with the back of the lock. That tail or tab will move the bolt that locks the door in or out. It could be something else entirely but without seeing it or having a better description of the type of lock I can't say much more about it.

Answer 3

Take the barrel out and see if it is turning while of the door their is like a little pin that moves round and locks the door if that not working or missing the lever in the door, if it does and only sometimes i would guess something is slipping in the door.and not the barrel The barrel is simple and does not often go wrong.Check what the barrel is having to move to lock the door,Sounds like somethings slipped,

Answer 4

It is probably the barrel. Squirt some WD-40 into the keyhole and on the key, then manipulate the lock with the key a few times. Don't expect instant results, but over a few hours things should be back to normal.

Answer 5

Barrels only turn the lock mechanism, it is more likely that your locking mechanism is either worn or broken
if you remove the door handles to see if the lock is worn
Try putting graphite on the moving parts not oil as this will only gunge it up more as dirt sticks to the oil
New Locking mech can be installed cheaply if req by suitable double glazing repairer

Answer 6

the tab on the barrel is worn yale locks from bnq are best about £25 and take 2 mins to fit.

Answer 7
