As a locksmith, one of the common questions that clients ask us about are deadbolts. Deadbolts, also known as deadlocks are an essential part of any residential or commercial security system and are designed to provide an extra layer of protection against forced entry and theft. Unlike a traditional lock that can be tampered with using a knife or intrusion tool, deadbolts are more secure because they extend deeper into the door frame, making them harder to force open. Deadbolts require a key or knob to unlock, making them far more difficult to bypass.
Types of Deadbolts
There are three main types of deadbolts:
Single-cylinder deadbolts are the most common type and have a keyhole on one side and a thumb turn on the other side. This is often found in public restrooms.
Double-cylinder deadbolts have keyholes on both sides and are often used on doors with glass panels or windows to prevent someone from reaching in and unlocking the door.
3. Keyless Cylinder
Basically the same as the double cylinder, except they’re not opened with a key but with a different type of a sensor such as a fingerprint, face scan or a password and only require a button to be closed.
Why are Deadbolts Effective?
Since they are well fortified and produced from solid steel, it is extremely hard and borderline impossible to be broken through using force. A common door lock can easily be broken through the utilization of a crowbar or a tool called “The Bear Grip”, while a deadbolt is far more complicated.
In addition, it takes much more time for a thief to go through a deadbolt. In this time, an alarm could be triggered, causing the thief to flee the premises.
Issues with Deadbolts
Deadbolts are mechanical devices and as such may be prone to issues like any other physical object.
If a deadbolt is not functioning correctly, one of the most common issues is misalignment between the door frame and the door. When a deadbolt is not aligned correctly, it may not engage or disengage properly, making it difficult to lock or unlock the door.
A locksmith can identify the cause of the misalignment and take steps to correct it, including adjusting the hinges or door frame, shaving the door or frame, or replacing the deadbolt.
In this video, there is a misalignment between the door frame and the door, causing the deadbolt to not go into the hole smoothly. This is a common problem that can cause the user to get locked in or locked out. In this situation, it is best to adjust the frame and the lock to go smoothly into the frame hole to assure smooth operation.
Deadbolts require professional installation: Although deadbolts may seem easy to install, it is crucial to have a professional locksmith install them. Poorly installed deadbolts may not function correctly and can compromise the security of the premises.
