All you need to know about locks and picking them

dom ix 10

Defeating the DOM IX

Last week I was forced to drill a Dom lock on a real lockout. I always feel bad when doing so ,even when sometimes it’s the only option (like glued locks etc.)

I’ve already covered the Dom locks in my blog and they are very hard to pick but possible. The trouble is on a real door when you lose the comfort of your vice and most of the time there’s a lock protector which makes it harder to tension.

I spent a few good hours on finding a better solution to this lock and found out that the  foil is the best way.  However there might be some problems when using this method.


I have five different  locks and three of them pick very easy,  one lock will pick but it will be impossible to remove the key after, I suspect the higher cuts( pin number 5) is going far too deep in the foil key , and the last lock will not pick and when I’ve looked more into the lock I’ve discovered that where it should have been pin number one it went all the way to the last pin for some reason. Also with this lock it is better to use pliers as bigger forced is needed.


To overcome those problems I’ve cut a substantial amount of the key  and since there isn’t a complex warding the key is working much better now  and will go on very smoothly.


Here is a video on how it’s done.






Also  here’s a quick look on my new lock  training borad I’ve made this week.


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
