When it comes to home security the locks on our doors are underrated but they are absolutely necessary to prevent strangers enter our property.
There are 4 important factors you should consider when buying a new lock for and here they are:
Security Level
You need to determine the level of security as locks are rated differently. For example locks for exterior doors should have a higher security rating than those for an interior door.
The American National Standards Institute (ANSI) grades locks on a scale from Grade 1 which the highest level to Grade 3 that fits low security or interior door is the best way to determine the security level of your new lock.

Type of Lock
There are many types of locks to choose from including doorknob, deadbolts and smart lock and each one has its advantages and specific uses.
Deadbolts are commonly used for exterior doors because of their strength when for interior doors you can be satisfied with just a doorknob.

Installation
There are locks that are easy to install yourself like deadbolts and doorknobs, but high security locks, smart locks and mortise locks might need a professional locksmith service. If you still going to install the lock by yourself make sure the lock you choose is compatible with the place you want to install it.

Cost
Basic locks are cheaper than smart locks or high-security locks. Remember the most expensive lock isn’t always the best one for your needs.
