Keeping your home safe is not something to take lightly, especially since burglaries and home invasions are on the rise. For these reasons, residents in Los Angeles, CA, are becoming more vigilant when it comes to protecting their treasured homes. In fact, many find installing double locks on your front door is an easy way to boost security. In this helpful guide from Kardo Locksmith, we will talk about the various types and benefits of this dual lock tandem. 

The Rising Importance of Home Security

Home security is not just a luxury anymore; it is a must-have. In Los Angeles alone, home burglaries have been on the rise since early 2024. Such incidents make residents and local authorities feel uneasy and alarmed. In fact, recent statistics reveal that a surprising number of these break-ins happen through the front door. Therefore, it only goes to show just how crucial reliable home protection is. 

With Los Angeles locksmiths, you do not need to worry. We have double locks, a trusty addition to your home security system, to keep things under control. These clever locks are like having a 24/7 security guard at your front door. They act as an effective deterrent to potential thieves. As a result, you can have an extra layer of safety and peace of mind at a fraction of the cost.

How Double Locks Work

Double locks are all about doubling up on security with two locking mechanisms on one door. Usually, this means a deadbolt lock paired with a standard knob lock, with the deadbolt sitting above the knob lock. Hence, this dynamic duo makes it much harder for anyone to break in, giving you a feeling of safety.

Types of Double Locks

Double locks come in a variety of styles and levels of security. Here is a list of the most sought-after combos:

Single Cylinder Deadbolt with Knob Lock

Many people use this kind of double lock. You can open the single-cylinder lock with a key from the outside and turn it with your thumb from the inside. The door handle has a key-in-knob lock built right in. When combined, they offer an effective barrier against break-ins.

Double Cylinder Deadbolt With Key-In-Knob Lock

The double-cylinder deadbolt, unlike the single-cylinder deadbolt, needs a key to operate from both the outside and the inside. This type of lock is useful for doors with glass panels. It prevents intruders from breaking the glass and turning the thumb turn.

Smart Lock with Deadbolt and Key-in-Knob Lock

Meanwhile, smart locks are an interesting choice for people who like new technology. With smart locks, you have the option to lock and inlock your doors using a smartphone app, a keypad, or your fingerprints. These locks, when used with regular hand lever locks, make things easier and the home safer.

Benefits of Installing Double Locks on Doors

There are many good reasons to choose double locks for your front door. Here are some of the best things about it:

Boost in Home Security

What is the main perk of double locks? Without a doubt, an increase in security! With two locks working together, burglars have a harder time getting in. Even if they manage to pick one lock, they still have to deal with the second one. This problem usually makes them give up and move on. It is like having a security team right at your front door.

Deterrent Effect

Double locks strongly deter potential thieves. Burglars may not want to break into your home if they see two locks on it. Instead, they will probably look for easier targets. Yet, double locks are more than just a physical barrier. When two locks are present, burglars perceive an increase in their chances of detection. This psychological effect can make would-be thieves just walk away.

Better Peace of Mind

With two locks, your front door makes you feel at ease, knowing that you can keep your home and family safe. It is important to remember, though, that not every lock is the same. While having two locks on your door is beneficial, it is crucial to invest in high-quality door locks that are resistant to picking, bumping, or drilling. Our locksmiths recommend buying a deadbolt or smart locks with advanced security features. These features will make your home even safer and give you even more of a sense of relief.
