All you need to know about locks and picking them

Dom lock

Dom Diamant (Diamond) – The Rolls Royce of Locks?

Here is a quick look of what must be one of the best engineered locks I’ve ever seen – the German Dom Diamant ( Diamond).

This lock was kindly given to me by Inalock from the DBC forum and was delivered by the almighty Mikey from Manchester.

First of  all this lock has a very unique key ,which  I can’t think of any way you can copy it without the real cutting machine.


The lock contains 10 discs that operates 3 (!) side bars

In the lock that I got one side bar was missing so I had to make a new one.

The side bars are in every 90 degrees of the core but one side is not a side bar but it has a spring attachment to it that prevents the discs from fully turning.


Inside the core you would find the discs with some very interesting spacers that look like four O rings which basically means that when you move one of the discs , the one next to it will move as well.

 This is the side bar  with the key in.

 The discs have false notches in them and they look like the letter B but some are in reverse.

Another unique thing that I learned from this lock is that discs do move  when the key is inserted/extracted  and unlike the Abloy they are not turned into a certain place which moves the bolt. In here the key immediately opens the lock

I’m still studying this locks but it is a very unique lock and very  very well made.

Dom Dimple Locks


Here is a quick view on 2 Dom locks I got

The top lock is  a Dom ix 5 HT  (Hope I’m not wrong)

The lower one is Dom ix 10 ,those are very good locks made in Germany

The Dom ix 5 is very interesting  as it got a sort of a trap pin and since it’s a very old lock I guess this is where the idea came from

Also it has one of the most nastiest  bottom pins I’ve ever seen!

Those pins have 2 rounds that can move inside of  them (like a brasless)

The ix 5 lock contains 5 pins and 5 side pins

 Here is the back of the plug with the other side pins,those pins will not effect picking but  they are great for master keying .

I did managed to bump this lock a while back though

The other Dom lock is the ix 10 which looks very hard to pick.

The  ix 10 contains 10 pins which are divided into 2 very close rows

The pins are rounded to the shape of the plug

Also there is plate cover on the other side of the plug which I belive is there so the plug can rotate smoother

Here are 2 of the bottom pins

I can safely say that the best way to pick this lock is via foil picking ,only trouble I see is the extracting of the key after,also the low pins might get overset (they would look like pin number 5)

I will try to test a few different methods with those fantastic locks ,will  keep you posted

For much more information I would advise to read Han fey’s fantastic articles about Dom locks

Locks Bumping

Bumping is a method that existed for years, but only in the last few years it was been exposed to the public’s eye, mainly through the internet.

A bump key is actually a key that is cut to the highest position, when you hit that key some pins will jump and with the perfect timing it would be possible to turn the plug. Some very high security locks surrender to this method.

Here is how it works..

This is a Linca lock from Spain, this lock has 5 pins and a side bar

A Fab lock that is almost impossible to pick

A Yardeny lock from Israel with 10 pins

Kaba 12 pins lock

A 7 pins Herman dimple lock

Magnum 7 pins dimple lock from China

The world’s smallest bum key? Only 3 pins
