Did you know that there are two different types of house keys?

Most people think that a key is a key, and that there are really no differences between them. You might be surprised to hear that all keys are different. The shape of the key differs depending on what type of lock is on your door. The two different types of locks that change the shape of the key are lever locks and pin tumbler cylinder locks. Let us now explain to you the difference between the two locks.

Lever Locks

An older form of a lock is called the lever lock. The keys for lever locks look more flat than a pin tumbler cylinder lock key. The key still has multiple ridges, usually two to five, but the top of the ridges are flat rather than pointed. Once you insert the key into the lock slot, levers move according to the height of each ridge on the key. If the correct key is inserted then the bolt will be able to easily slide into the lock allowing the door to open. Lever lock keys tend to be larger than other keys. This is great if you are carrying multiple keys because you are able to find it easily. It is also a slight inconvenience because it may not lay flat on the key ring.

Pin Tumbler Cylinder Locks

The most recent type of lock used is the pin tumbler cylinder lock. The matching keys have ridges or grooves on the sides of the key. These ridges are pointed unlike the flat ridges on the lever lock keys. Once this key is inserted into the key slot, a series of pins move up and down until they are in line with the shape of the key. Once the key is fitted correctly into the lock, you can twist it and the lock will open. These types of keys are predominantly used in the United States where as the lever lock keys are usually used in European countries.

So what is the best type of lock for home security?

There have been no tests to see which lock necessarily works better; it is just that one type is more technologically advanced than the other. The both are able to lock your doors and keep you safe.
