Which type of lock is this?

by **marmar** » 10 May 2004 12:31

I could not find any information about locks with keys like the one in the included picture. The key is flat piece of metal with the indentations at the end; door locks/unlocks by inserting the key in the thin rectangular hole and pressing the door handle. I would like to know the type of the lock and how secure is it.
Thanks.

When the door is locked about 12 metal pieces come out from all sides, and unlocking retracts them.
I have bought the door in Europe, but I am unsure if it's sold worldwide so I put this topic here.
Oh, and I think that they called this type of lock "One touch lock", if that means anything to you...

These kinds of locks are "push lever" locks. You dont turn the key is that correct? These locks were common as padlocks in the US about a century ago. Like almost every lever lock in the US, the design fell out of favor for one reason or another. I would guess that your lock was made by Fichet or some other French company, as I know of at least one Fichet "push lock". These are lever locks, probably with several false gates per lever. I would guess they would be Secure against picking, but overall security of course depends on how well your door is installed etc.
Historically, All of these style locks probably owe a good deal of their design to Jos. Bramah. Even though his lock used rotation, the "push lever" concept was right there, ready to be developed.

difficult to say woithout any picture

it could be a BRICARD french lock or a MOTTURA Italian one

Ho ... sorry ...

if you don't turn the key it is neither a Bricard lock nor a Fichet or a Mottura lock

Nope, I do not turn the key, just insert it into the thin hole until it clicks.

It looks a lot like this one:

look attentively on the small differences between the both keys to identify the right one

they work more or less on the same way unless on the Bricard lock there is only one main spring and on the Mottura there is a spring on each "slider"

the bricard has a kind of disks moving in rotation from its axis and the mottura the sliders move inward/upward in the lock core with an independant spring for each slider

you could test your lock with a wire or a pick to identify which lock it is if you cannot see the differences on the key you own

hello folks, howstuffworks.com featured on their homepage today an article on lockpicking. i was mortified by the description of how easily pin and tumbler locks could be defeated.

i am using a mottura lock of key described below (due thx for ascii art i borrowed off another poster here).

you have to turn the key for it to open. it is referred to in catalogues as a pump type lock but i do not understand what the term pump refers to.

what i would like to know is if this design offers better security than a pin and tumbler. i forked out â‚¬180 for it(it was the most expensive in the shop and had the biggest key) . the link below also shows the lock itself. is its design secure because it is harder to pick or harder to destroy than a pin & tumber? thanks

Hey peeps, I've noticed people struggling to get ASCII art looking right, so here's a helping hand. If you use the code and /code tags around your diagram all the spacing will come out right and you won't have to worry about the formatting getting messed up. Here's an example:

Code: Select all: Top view: BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB KEY HANDLE HERE BBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhh B - metal h- plastic handle Side view: hhhhhhhhhhhhhhhhh BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBhhhhhhhhhhhhhhhhh hhhhhhhhhhhhhhhhh

The only problem is the annoying Code: label, but you can't have everything. Hope this helps!

Why did you choose 'B' and 'h' ? :lol:

>Why did you choose 'B' and 'h' ?

ask marmar...i copied it off him.

anyways these mottura are also similar to fischer 5000 types. what i am curious about is if the larger size of the lock and key make instrusion any more difficult. after reading some info here it seems a larger key means a larger keyhole which makes picking easier.
anyone know what pump means?

thx

This is a straght jack rectangle lock. i have only managed to pick one once. they are very secure because u need to lift the 2 bolts in the back of the lock and the pressing of the door knob locks it into place until you lock it again. you have to double pick it and be able to twist and push the door handle at the same time. hope that helps.

Hi

in Fr we have a lot of pump locks ...

even you cannot pick these locks without the right tools (some special picks are designed for this purpose) these locks are really easy to decode in particular the Mottura lock cause all the pins are facing you unless two - hidden by the edge of the lock entry but can be decoded too - no security slider pin -

I guess I could not explain you the right technique in an opened forum

so after decoding it is really easy to make a key or to use a "variable key" (a key with some precut rods with the length of each cut used on this kind of lock)

cause all the pins are facing you

I had a feeling this would be a weakness

looking into my key hole i can see the shape of my key.

hard to pick. but easy to make a key. what a stupid design.

it cost me a fortune! i chose it because it had a big key! and to make matters worse the big key feels bulky in my pocket.

just out of curiousity, what type of lock do you folks around here have on your house door? or do you leave it unlocked

?

thx
