Last week I got the new mul-t -lock XP cylinder from Fooddude of Island forum (thank you mate!) . There was a lot of buzz around this lock and since it had manged to achieve the SS312 Diamond level of accreditation for a lock cylinders I was very curious to see the inside of this lock.
The XP lock is basically an improvement of the Garrison break secure lock that was also introduced by Mul-t-lock.
The lock has a broken secure cut but in a different position right before the 5th pin which is NOT available in the secure side.
It is also contains the “half-moon” anti drilling which I see for the first time in a lock outside of Israel.
The plug has 2 extra anti drilling balls
The plug has only 6 pins (camber number 5 is blocked)
Since every Garrison must have a number 6 pin because it’s the anti drilling pin this leaves us with only 5 power 6 which are 7,776 keys combinations that are not a very good ratio.
The bottom pins are all mushrooms and this lock is very hard to bump and impossible to use a foil picking method with.
The last pin is also anti drilling .
The anti drilling pins
Now all this is very nice but the major issue in the XP is the cam design. The plug doesn’t have C clips- it’s the cam that is actually holding them in place.
The cam designed as 2 pieces with a circle clip holding is together, which means that if the lock is attacked the cam can not break and I can imagine that a lot of strength is needed to pull it out, in other word the other side of the plug must be snapped in order for the cam to release and even then it will cause a lot of mass inside the lock mechanism .
All in all I find this lock to have a very clever design and would definitely do the job, picking this lock however is very easy .
