Locks are the primary source of protection for any house or office. Door locks that look good and strong on display may not always provide the desired security. There are indeed better security options like live feed from CCTV cameras, but sometimes, all you need is an excellent door lock to keep your house safe.

If you are buying a secure door lock, you have clicked on the right article. Here, I have discussed the 15 most secure door locks to simplify your purchase decision.

Features of a Secure Door Lock

The most secure door locks are those that not only provide security but are also hard to replicate. Even though break-ins have declined, burglaries are still common in houses.

Multiple factors are considered when choosing and purchasing a door lock. These include:

  • Ease of installation
  • Temporary accessibility
  • Scheduled access
  • Locking and auto-locking
  • Pricing
  • ANSI ratings

After choosing and installing a door lock, people also opt for additional protection like Door Reinforcement Locks.

Every lock must have a grading from the American National Standards Institute (ANSI). This is to identify how strong a lock is in terms of durability and security. Every lock can be classified under one of three grades:

  • Grade 1. These locks are of the highest quality and are usually found in industrial buildings. However, they are now getting commercialized, and most locks in this list fall under the grade 1 category.
  • Grade 2. The grade 2 locks are the ones that are most commonly used in residential houses. These are made from hardened steel and are strong enough to keep most intruders away.
  • Grade 3. This is the lowest level, and hence, the quality is also low on these locks. The steel is sub-standard, and the locks do not provide a high level of protection from threats.

The Most Secure Door Locks

Choice of door lock depends on whether you want a simple deadbolt, lever handle lock, or a smart lock. Customers also buy locks that are available in colors and finishes suitable for the interior decoration of their offices and homes.
