Removing a lockable door chain after keys have been lost

I'd have to say angle grinder. Probably try to go "under" the cylinder but above the "flange". Alternatively grip it *very firmly* with a mole wrench and rock backwards and forwards, to try to loosen the screws. Provided these are not too long, you may be able to remove it without causing damage that can't be concealed by the new one.

Dremel the bit of metal that's in the way with a thin cutting wheel so it falls in half.

I would think a big screw driver in the lock will turn it enough for the latch to work.

Angle grinder.

Just curious but why on earth does it have a lock? The only function of the lock would appear to be to stop someone (on the inside) using the chain as a security device.

Unfortunately, when I went to remove the old one, I discovered the latch on the end of the chain prevents access to the lower securing screw.

Can anyone suggest a removal solution that doesn't involve drilling out the barrel, jemmying off the old hardware or calling out a locksmith?

Thanks in advance.

In picture 1, surely you only have to drill through the part of the latch which is obscuring the screw ? Which is presumably what's blocking off the bottom hole. Drilling a large enough diameter hole through the latch will then allow you to either access the screw with enough head left on it to turn it, or drill off the head completely, remove the latch fill one of the holes and reposition the latch so as to cover the other hole still containing body of the screw whose head you've just removed.

Presumably to stop people who've entered the house by some other means, a window etc from easily exiting via the front door when carrying bulky items .

Along with the lock you get a sign to put on the wall.

"Please do not attempt to jemmy this lock off of the door as this can damage the wood "

Um, no. The lock seems to only serve to prevent you putting the chain on, not to

Doh, ignore all that. Meant to cancel that post before sending. I misinterpreted the photograph.

Its there so you can get in when your elderly parent has put the chain on and gone to bed, fallen down, etc.

Well spotted . Because when the door chain is at its stretched taut enough for somebody to get their hand through the door they obviously can't get the chain back far enough to the other end of the slot to unhook it. Whereas they should be able to use a key.

The fact that you're normally only supposed to put the chain on before opening the door ( presumably ) is no guarentee of the above scenario not happening.

I wouldn't worry about it. I don't think an unfamiliarity with door chains and their operation is anything to be ashamed of. If people on UseNet only ever posted on topics in which they were truly experts the place would soon be empty, as the experts would soon get lonely.

father in law had one on his door and he used to slide the locking part together so it was on when he was OUT the house and used the key to re-enter, was a bit fiddly but I suppose he felt better with the extra security, but hey a hefty kick and you would have busted it.

That's what I was going to suggest. Highly likely to work.

Burglars really care about that sort of thing.
