Knowing how these and others actually work, may help you narrow down your options.

  1. Deadbolt Locks

    Most people don’t realize that there are three different types of deadbolt locks, double, single and thumb turn deadbolt locks. Single cylinder deadbolt locks are used most commonly in homes. This is when a key cylinder is used on the exterior of the door with the thumb turn on the interior of the door that allows you to open the door. The only downside to this type of lock is that you will always have to have the key to open from either side. This could pose a real safety threat because if you’re unable to locate the key, you won’t be able to unlock the deadbolt. Having a key on the inside of the door is recommended in cases of an emergency. The thumb turn deadbolt offers both the single and the double cylinder. The thumb turns inside functions like a single cylinder deadbolt. The only difference is that a thumb turn deadbolt can be locked with the key. Maximum security is offered when you sue a thumb turn lock.

  2. Padlocks

    A padlock is a secure lock but it isn’t permanent. They come in various sizes and easily be moved to wherever they are needed. There is a combination padlock or a keyed padlock.

  3. Rim/Mortise Locks

    You will often find these types of locks are used for commercial doors and in apartments. These two locks are similar in certain areas but use different hardware. The rim cylinder lock is placed on the inside of a door. It has a long metal piece that goes into the back of the lock, which eventually connects with the lock mechanism on the opposite side of the door. A mortise lock has hardware on the inside of the door. The lock uses a cam to connect the locking hardware and is held together by a setscrew. These types come in different lengths and are offered with a different cams depending on the type of mortise hardware that is used.

  4. Knob Locks

    The knob locks are typically found on the exterior of the home door. These types of locks should not be used as your primary lock. The lock cylinder on a knob lock is situated inside the knob and not inside the door. This means it is easy to break the knob and gain access the lock and unlock features. This type of lock is a lot more useful for doors inside your home and should be used in addition to a deadbolt lock, if used as a primary lock.

  5. Lever Handle Locks

    The lever handle lock is often installed on the interior door of commercial businesses. They provide easy accessibility by simply pushing down on the handle to open. The lever handle lock makes your business handicap accessible.

  6. Wall Mounted Locks

  8. Rim Latch Locks

Again, this wouldn’t be the type of lock that you would want to use as your primary lock without using another more durable type of lock, such as a deadbolt.

  9. Interchangeable Core Cylinder
