No matter how big or small a house is, we all look for the best security lock for our home to keep our property safe. The front door is, unfortunately, one of the prime locations for burglars to break into a home. Therefore, it is essential to install high-security locks on a front door. A proper security lock is the first line of defense against intruders.  

Types of door locks

However, when choosing the best security lock system for your front door, you will be overwhelmed by choices. There are many different types of high-security locks for a front door, from advanced smart lock systems to traditional deadbolt locks. The following are the different types of commonly used door locks.

Door chain locks 

A door chain lock is a chain restriction designed to stop an intruder from entering your home when you open a door.  When engaged, the chain is connected to the door frame to the front door.  There are two main types of door chains: a standard door chain (non-locking versions), and a lockable door chain.    There is also a door chain restrictor which is used on composite doors and features a ring on the end of the chain the hooks around the door handle.

Doorknob locks 

Although a doorknob lock is commonly used on inner doors, you can install it on a front door in combination with a deadbolt. This type of lock will have knobs on either side of the door. You have the option to choose a single- or double-cylinder lock installation.   

Barrel bolts 

A barrel bolt is installed on the inside of a door. There are two separate pieces with one installed on the door frame, and the other locking assembly is installed on the door. The locking assembly includes a cylindrical lock, which you can slide into the catch that is fixed on the frame. 


Deadbolts provide an extra layer of security on top of a doorknob lock. These types of locks are available in single- and double-cylinder designs. A deadbolt will provide an additional level of protection for your front door as it is built into the wood frame of the door itself. 

Cam locks  

A cam lock typically requires a key to lock or unlock it. They are available in flat and tubular designs and used mostly used in cabinets. They are one of the simplest locks available in the market. 

Digital locks 

Digital locks are mostly used in hotel rooms, schools, and institutions. A keypad or card system is used to lock or unlock digital locks. You can install a regular key system along with digital locks so that you can open it if you do not have your card. 

Smart locks 

Similar to digital locks, smart locks do not need keys. They are integrated with Bluetooth or similar technologies. You can enable remote access control using your smartphone. You will also get alerts if an unknown user attempts to unlock the door. 

How to determine lock quality?

Regardless of the type, a lock is as good as the quality it is made of. A qualified residential locksmith will help you determine the quality level needed for your home. Here are the three different factors that will determine the quality level of a lock. 

Lock grade levels 

The first step in determining the quality of a lock is to check the grade level given to it. Locks are graded according to the durability and how capable they are to withstand break-in attempts. The grade “ratings” is issued by the American National Standards Institute (ANSI) and can carry a grade of 1, 2, or 3. Here are the different types of lock grade levels. 

  • ANSI Grade 1 – For the highest protection level, you can choose a lock with a Grade 1 rating. This type of lock is the most used for commercial properties and industrial establishments for enhanced security. It can be used in residential settings as well. However, it is a bit expensive when compared with other grade locks.
  • ANSI Grade 2 – This is mostly suitable for residential applications and can be used for light commercial settings. You will find it generally in apartment buildings. It is highly durable but not heavy-duty as the Grade 1 level. It is a budget-friendly option for homes. 
  • ANSI Grade 3 – This is the lowest level of lock quality rated by ANSI, but it is good enough for residential homes. It meets the necessary security requirements for residential properties. It works better than many other non-ANSI security locks. 

Proper installation

While a lock installation on a front door might seem like an easy DIY job, a professional locksmith would be a better option. Each lock is different, and each door is different. A locksmith will know how to align a new lock and door correctly so that a door will close properly.  If they are misaligned, this can cause damage to a door, especially as the seasons change and a door expands and contracts.  By looking for locksmith services, you can find a residential or commercial locksmith that has experience in installing locks in all types of doors. 

Strike plate quality

A strike plate is the metal plate that is attached to the frame of the door. If the strike plate is of low quality, it may bend easily when someone kicks or hits the lock. Ideally, you should choose a lock that comes with a high-quality strike plate for better protection. 


A front door is the first thing that people see when they come to your home or office. The lock you choose for your front door should be stylish while providing strong security. Once you understand the different types of door locks, choosing a high-security lock becomes easier. Hiring a professional locksmith will ensure better safety and a proper lock installation.
