At the second attempt bought on Ali cylinder mechanism (striker) with keys that are almost impossible to copy.
The key is inserted into either side horizontally.
Included are two key slots (type A) and six slits without (type B).
First striker opened the keys A, but only once it is inserted B keys, A stop working. This is done to ensure that the keys And you could give builders, while there is a repair, and when repair is complete, plug the B key and then use the key B. In fact a lot of sense in this case, two types of keys is not present, as they differ only a slot - groove seal when in keys A (e.g., epoxy resin), they become keys B.
The larva is sold in a tin box. Included is a lubricant graphite powder, but the screws for fastening to the castle there - are encouraged to use the screw from the old larvae.
The larva has a standard size and fits to the Russian and European castles.
Buying larva on Aliexpress, you need to carefully watch the size - there are larvae in two sizes: regular and reduced, not suitable for ordinary locks. For the first time, not knowing this fact, I bought such
reduced larvae (ammo1.livejournal.com/1006057.html)Which are now lying "useless burden."Of course, the Chinese written about the maximum vandal resistance and resistance to any type of master keys. What is the situation really is hard to say, but certainly the cylinder mechanism is protected better than ordinary "English", which opens a master key for a few seconds and it will likely better than normal larvae perfoklyuchami.
I bought this bot for $ 19.76 with free shipping.
