Warding is the use of wards or barriers that a key must navigate around in order to operate a lock - not a new practice by any means. A truly strong lock should have some special features, such as restricted keys, specialty pins, or even abstract features, such as warding, making not only brute force but also more well-planned attacks more difficult to carry out. The addition of these special pins, such as spool or serrated pins, is commonly used to thwart more thought-out attacks. The more precise a lock is - through machining parts rather than casting pieces, intense scrutiny during quality control, and the use of quality materials - the less room there is for attackers to defeat it.Įven relatively cheap locks typically offer solid construction, and most even have security pins thrown in for good measure. Good locks are also precisely machined so that the tolerances between the moving parts are very small, making “smart” attacks like picking or bumping more difficult. Today’s locks are most often made of bronze, stainless steel, or similar metals, both for strength and corrosion resistance. So, what makes one lock better than another? With locks costing anywhere from $10 to thousands, there are a plethora of factors to consider when choosing a lock for your possessions or for the doors to and within your residence. Locks are your first line of defense against theft and burglary. When was the last time you evaluated the physical security of your home or your bug-out shelter? The devices we consistently rely on, but seldom give much consideration to, are locks. We’re talking about guarding the things you have from the people who want to take them from you. The mechanism can be seen in action, in the following animation.A lot has changed throughout history, but one thing that’s remained constant - and probably always will - is how we protect our valuables.

This action is then similar to a normal lock in which the pins now fall into their correct position in the key bitting, and the pins are at the shear line and the cylinder can be rotated.' Once the key is rotated to the top of the lock it is pushed in a little bit farther. 'At the same time the slot cut in the key allows the key to travel around an internal shield within the lock. 'The key must be first inserted and then rotated 180 degrees to the top where the pins live,' Ryan explained to us at the time. In the Bowley system, however, the key doesn't engage the pins upon first entering the keyhole. The problem with such systems is that a lock pick tool can also easily be inserted, then used to push up the pins. Once it's fully inserted, all the pins have been pushed up to sit evenly in a line, allowing the lock cylinder to be turned.

As it does so, its cuts (the uneven bits along the side) push up on the pins.

Now, he's back on Kickstarter with a very beefy padlock that incorporates the same proprietary technology.Īs we first explained three years ago … in a conventional lock, the key enters a pin tumbler as it's inserted into the lock. Back in 2015, Canadian inventor Ryan Bowley successfully crowdfunded his deadbolt Bowley Lock – it was claimed to be virtually pick-proof, yet still affordable.
