detector lock

[dazza]

HI

i have just been reading a lock book and came across this lever lock where it has a detector lever. a lever that lets the owner know if the lock has been tried to open with false key or implement. the lock has a lever amongst other levers inside the lock that if someone over-lifts anyone of the levers they get caught and held up in the over-lifted position. and when the owner puts key in and doesn't turn like normal knows that someone has been trying to manipulate the lock.
do they still make these locks if so do you come across them much.

The Chubb Detector lock is a very old design. I don't think they're made anymore -- certainly not by Chubb, which has gone out of business.

HI eric343

your probably right its a old book what i have got for some reason i thought it was union because that's what name keeps popping up in book no other makes. i wonder why they stopped making them it looks like a good idea.

Would that mean then that the owner is unable to operate his true key if someone had tried a false key? In that case he would be locked out of his own house, needing a locksmith, and if so, I can see why they never caught on with the public.

You just turn the key in the lock direction to reset the levers.

by turning the proper key in the reverse direction lets the owner reset the lock'

HI

sorry about that shrub

i cant understand why you can only find these on old locks. i think its very good idea because it lets the owner no if anyone has been trying to bypass the lock.

I guess there is a certain logic behind not continuing the use of that kind of lock. If you think about it, why would you want to know if someone was trying to get through your lock? If they couldn't do it, then your lock is fine, no need to upgrade it. On the other hand, if someone was successful in the defeat of a lock, you will definitely know about it, you don't need a lever to tell you.
Additionally, i suspect that the security measures that are in place on medeco style locks are superior in form. I would be very interested to see whether the demise of this lock style was concurrent with the rise of a new type of anti-picking technology.

Just a couple of thoughts, i'm not trying to say the lock was good or bad, just thinking out loud.

The detector was a good lock, but it is far from "pickproof".
