Deadbolt locks are designed to provide extra security for exterior doors. They include a solid bar that slides into the door frame when locked, and they’re not easy to pick or manipulate. However, not all deadbolts are produced with the same features and standards. If you’re considering adding this type of security to your home, here are some factors to consider.

3 Features of Quality Deadbolts

1. Bolt Length

Deadbolts effectively prevent forced entry because there’s a solid metal bar protruding from the door directly into the frame. However, if that bar isn’t very long, an intruder could easily apply enough force to break the frame. Generally, bolts that are at least one inch long are more secure than shorter bolts.

2. Testing Standards

Certain products are tested against a set of universal standards to provide peace of mind for customers. For deadbolt locks, achieving a Grade 1 designation from the American National Standards Institute means the lock has been tested to prove it can open and close at least 250,000 times and hold up against at least ten blows from a hammer. Some locks also meet UL 437 tests to prove they can withstand picking, prying, and drilling.

3. Functionality

Some deadbolt features are simply a matter of preference and home characteristics. For example, some locks are double barrel, meaning you need a key to lock and unlock them from both sides. Others are single barrel, meaning you need to unlock it from the outside but can easily turn a knob to lock and unlock it from the inside. The latter is generally easier to use, but the former may be more secure, especially for doors that include breakable glass, since an intruder could potentially break through the glass to unlock the bolt without a key.
