Do I Need A Deadbolt Lock?

If you are concerned about your home’s security, you may be wondering if you need a deadbolt lock. The short answer is: yes! This article will discuss the key advantages of having one installed in your home. If you need help installing a deadbolt, don’t hesitate to reach out to your local Brothers Locksmith today. The experienced locksmiths at Brothers Locksmith can install a deadbolt quickly and affordably.

Deadbolts offer specific advantages that standard locks do not have. A deadbolt, with its solid steel bar, makes it more difficult for a burglar to break into your home. There are three main types of deadbolt locks: single cylinder, dual cylinder, and keyless cylinder. The most common used is the single-cylinder deadbolt, which is operated by a twist knob on the inside and a key on the outside of the door. The double-cylinder deadbolt requires a key on both the inside and outside for operation. Keyless cylinder deadbolt locks use a password or fingerprint scan to open the door.

Keep in mind that a single cylinder door can still be breached if you have glass panels or windows, as a burglar could break through the glass, reach in, and turn the knob. A double cylinder protects against this type of break-in, because a key has to be used on the inside to unlock.

When installing the lock, the deadbolt must extend fully into the hole on the door jamb for it to function properly. It’s essential that the hole is reinforced with a metal strike plate. If the deadbolt does not extend all the way into the hole, or if a metal strike plate is not used, the lock and door frame can be compromised during a break-in.

Standard locks can be pried open with objects such as a knife because of the spring mechanism. They can also be broken open by crowbars. Because a hardened steel deadbolt is stronger, forcing or sliding them open is nearly impossible.  Deadbolts take longer than standard locks to break open, meaning a burglar is less able to get in and out promptly and, therefore, is more likely to be caught.

Often, when a burglar kicks in a door, it’s the door frame, rather than the door, that breaks. Some locksmiths recommend using a 3-inch screw to reinforce the strike plate and make sure it’s securely attached to the studs of the frame of your home or apartment.

Another advantage of deadbolts is that their simple mechanisms make them extremely affordable. Expect to pay between $30 and $50 for a deadbolt – a cost much less than installing a home alarm system. You may not even need a sophisticated alarm system once you install a deadbolt. While no lock is 100% guaranteed to keep out intruders, installing a deadbolt, as opposed to just having a standard lock, will significantly increase the security of your home.
