A Little Background

Locks can be installed not just on doors but also on windows and any kind of entry and exit point in your house. Sure, the lock can be picked by someone who is expert at picking locks to get in your house, but that does not mean that you can make it trickier to destroy the lock, buying you enough time to call the police or take action against the intruder in your home.

Door locks come with deadbolts other than the keys so that they can be harder to open. Deadbolts can be somewhere within 1 inch of thickness. The deadbolt is a great locking mechanism that is used on almost every home door possible to keep other unwanted people from accessing as they will be picking the lock in a more difficult way.

There are also various kinds of lock mechanisms, such as the side bar locking mechanism, the pin and tumbler mechanism and the rim lock, which uses a small latch system. There is also the mortise lock which is unique and usually comprised of a deadbolt and a latch bolt system. There are also modern locks which use electronic keypads and some even use fingerprint scanners.

Keyless door locks also eliminate the chance of burglars or thieves looking for a spare key, since homes that use a keyed system will have a spare key hidden somewhere, that of which most evildoers are very much aware of.

How We Picked

In choosing the best door lock, you must consider the following factors first in your decision:

Type of lock: a door lock can be any of the following: electronic, mechanical (uses either keys or a latch system), keyless, fingerprint (biometric), mortise, magnetic, deadbolt or even WiFi powered. With any kind of door lock that you purchase, it should be one that will meet your needs. For instance, the door lock that is mechanical or keyed is more ideal for the regular residential people whereas electronic locks are more ideal for bigger houses and public establishments.

Type of material: most door locks are made of stainless steel so that they will not get corrosion easily. You also have to know the stainless steel grade or gauge to make sure it is of high quality. The door lock should be made of high quality material and this is why some door locks are made of brass material so that they will not get easily destroyed by elements or by intruders. Just make sure that the door lock will not be easy to remove so that if ever it is made of brass material or any kind of expensive material, the door lock will not be easily taken by thieves and the like.

Intended door location: the door lock can be placed on various places but you have to consider where you will place it. For instance, if you want to install a door lock on your main door, make sure it is totally secure compared to the inner doors in your house. Main door locks can be either electronic locks such as fingerprint locks or keyed locks, but the most commonly used door lock for main doors would be the keyed lock or an electronic lock if possible. Inner door locks can be of lesser quality but still provide enough security, such as latch locks and the like.

Number of combinations (keypad): if you have a door lock that is keypad powered or provide a keyless entry system, make sure that the door lock will have enough combinations for you to store so that many people can be able to access it easily.

Backup key system (electronic locks): consider a door lock that has a backup key system, if it is keyless such as a electronic keypad door lock, a fingerprint door lock or any similar mechanism. A backup key is very important because once the mechanism of the electronics fail, you will have yourself a safe emergency lock to open.

Ease of installation: the door lock should be easy to install onto your door. It is important that the door lock can be done with great ease, even if it might require a locksmith or a mechanic to install, especially for those with keypads and the like.

Ease of entry without compromising security: consider a door lock that makes it easy to get in and get out for authorized people but hard to access for unauthorized users. A door lock that upholds safety and security yet does not compromise the ease of entry is a good door lock to have.

Door fitting: make sure that the door lock can be easily fitted onto the door that you want to install it to. You should consider the door lock that is not too big and not too small for your intended door location.

Durability and resistance: consider a door lock that is not easy to pry open, to destroy with power tools or to take apart using other items or brute force or careful lock picking.
