Unless you are a locksmith or a lock picker, you likely do not understand what makes one lock more secure than another. This puts you at a disadvantage when you are choosing a lock for your business. If you have something of value in your building, then you need to make it as secure as possible. Thus, having an idea of what makes a lock secure will help you to choose the most secure locks that money can buy.
One way that thieves can bypass a lock is to make their own copy of your key by ordering a key from a locksmith. Some key and lock systems are so unique that they can receive patents for their keys. This makes it illegal for anyone but the owner of a particular building to order a replacement key. Buying exclusive rights to the keys used in your building is one way to make sure that there are not a lot of duplicate keys floating around. Ask a locksmith which brands of locks will sell you the exclusive right to duplicate the keys in your building.
Number of Tumblers
The number of tumblers a lock has will make it more or less difficult to pick. If a lock has three or four tumblers, you will have three or four corresponding ridges in the key. A lock picker will use specialized tools to hook these tumblers and turn the lock. More tumblers make the lock harder to pick because a thief has to feel for and hook them. When in doubt, err on the side of more tumblers rather than less.
Some locks will have more than just tumblers, which must be carefully aligned. A sidebar leg is deployed by an angled ridge on the key. Thus, a thief who has lock picking tools to hook tumblers will likely not have tools that also allow them to hook sidebar legs at just the right angle to allow them to properly align.
As if increasing the number of tumblers and integrating sidebar legs into the lock design was not enough, the most secure locks will also include a slider. This is a mechanism that is engaged by a groove on one side of the key and slides back into the lock as you insert the key. This means that even if a thief could get past the tumblers and sidebar legs, the slider would still prevent entry.
There may be other components that are included in lock, but suffice it to say that the more mechanisms a lock integrates before access is granted, the more difficult it is for a lock picker to get in. This will also make the lock more expensive, but sometimes you have to spend money to protect your valuables. Contact a company like Vista Lock & Safe Co for more information.
