The Most Secure Locks

The Most Secure Locks

At CLK Supplies, we know that a lock is pointless if anybody can open it. Although technology has changed a great deal since the earliest locks, the main goal remains the same—to protect homes, possessions, and secure areas from unauthorized access. That’s why the strongest and most secure locks never go out of style; they can only be opened with special locksmith tools.

However, modern home security locks come in all shapes and sizes, and it can be easy to get overwhelmed with the sheer array of different choices. Everything from keyless entry systems to entry lock sets can confuse inexperienced customers. That’s why it’s so important that locksmiths be able to articulate the strengths and weaknesses of each type of lock, so that they can help their customers protect their homes. Here are some of the most common types of house locks—and how they hold up against trespassers.

Spring Operated Locks

Ideally, a good lock should be unopenable without either the correct key or a specialized set of locksmith tools. However, one of the most common types, spring-operated locksets, are not very secure. Also called doorknob locks, these locksets are extremely convenient—locking with merely the push of a button—but can easily be opened with lock picks. Additionally, they may have the advantage of being able to be locked from both sides, but since they work merely by locking the doorjamb in place, they are also vulnerable to brute force attacks. Lazy criminals will often simply kick a door in rather than attempt to unlock it. Generally speaking, spring operated locks are a good idea for privacy purposes, but aren’t always the best choice for exterior doors. They work well for bathrooms or bedrooms, but shouldn’t be the only lock on a front door.


Another common type of lock is a deadbolt, a thick, heavy bar that uses no springs to stay in place. These locks are extremely durable and long-lasting, and can withstand a great deal of strain. Although this lock can be opened with the right locksmith supplies, it is very difficult for amateurs to break into, and can often prevent a door from being kicked down or otherwise forced open. Many residential and commercial properties use deadbolts in conjunction with spring-operated locks to provide a solid amount of protection. Most home security experts recommend that homes have a deadbolt lock to protect against common criminals.

Combination Locks

Once increasingly popular lock choice is a combination lock. Although designs and models tend to vary, most combination locks involve an electronic keypad in conjunction with a solid bolt that can keep the door from being opened. These locks also offer the advantage of eliminating the need for keys; all the homeowner has to do is create an entry code. Combination locks are generally almost impossible to break into, although not all models are created equal. Additionally, they tend to be pricier than many other lock options.

Mortise Locks

Finally, mortise locks are an extremely secure type of lock, where the locking mechanism in placed directly in the door frame itself. A pocket or notch known as a mortise is carved out and the mechanism is installed using specialized locksmith equipment. These locks are appropriate both for wooden and metal doors, and provide a great deal of security—since they are difficult to manipulate or break into. However, they must be carefully installed by a highly trained locksmith in order to ensure maximum security.

Unfortunately, no lock is invulnerable, but in most cases, they don’t have to be. For residential purposes, a mortise lock, combination lock, or doorknob and deadbolt combination will do just fine. Choosing the right lock is an essential step in protecting a home, which is why it’s so important that locksmiths know the differences between and advantages of each type.
