Resistant Locks

Resistant Locks

When a broader categorization of locks is concerned, there are those that fall into the category of resistant locks. Other categories of this level are basic locks, high security locks and ‘unpickable’ locks. The differences among the mentioned categories lie in the level of security they provide, starting from the basic which provide almost no security at all, to the ‘unpickable’ which provide the highest security level. However, this article will deal with the category of resistant locks.


The resistant locks seldom find their way to the shelves of a hardware store. However, you might also find certain locks labeled with ‘hardened’ or ‘pick resistant’ and whereas s


ome of the products that are labeled like this really meet the promised quality, most of them are actually just regular locks that will provide you with security no higher than that of a basic lock.
Accordingly, a resistant lock should entail certain set designs and features that would really give some trouble to and prevent the potential attacker or a burglar from breaking onto your property. In fact, a resistant lock is to prevent a typical housebreaker from defeating in under five minutes. This will also prevent those with no picking skills to break in by simply bumping or breaking the lock.

The features that these locks usually have installed are the so-called anti-pick pins which are also called security pins, spool or mushroom. The keyways are also very tight and they can make the use of the regular picking tools a lot harder. Thus, such a lock can easily resist the actions of basic picking. Padlocks are one of the locks that belong to this class and they have the so-called double-ball mechanism installed in them as well as locks that are keyed and require anti-bump pins. Thus, the risk is almost reduced to zero.

However, although it would ensure the incorporation of the mentioned features, the package and labeling for this class of locks are not standardized. In fact, the term ‘hardened’ and the similar usually refer only to the shackle and because, they can easily be broken with the use of bolt cutters, crowbars or any kind of forced attack.  The locks that are really resistant are hard to find in the hardware and the reason why basic locks are more available and easier to acquire than the more reliable resistant locks remains unknown.

All in all, resistant locks provide a higher level of safety than the basic ones. They incorporate many features such as anti-pick pins or double-ball mechanisms that make it much harder for a regular attacker to defeat them. However, they are hard to find and the regular hardware shops do sell some, but the quality of those is quite questionable. In fact, although they are labeled as ‘hardened’ or ‘pick resistant’, these terms usually refer to their shackle and outer housing rather than to the mechanism itself. Anyway, if you can find a lock that is really resistant, it is recommended to replace the basic one with it.
