Most Common Locks On The Market

The most common locks

Have you ever felt overwhelmed when trying to buy a common lock? The truth is that there is a broad spectrum of different locks for home and business needs. As we use locks daily, we must understand the other options available, considering functionality and security factors. Today, our locksmith company near me will show you the most common locks on the market.

If you are new to locks, this article will help you decide which lock to acquire, but if you still have doubts about it, you can always call your favorite locksmith to get all the extra info!



Padlocks are the most common type of lock in the market and the most popular and easy to identify. Padlock replacements have different sizes and are freestanding and portable. The market has two types of padlocks: The combination padlock and the key padlock.

In the case of combination padlocks, these have one or more numbers to dial to open the correct combination. However, these are often easy to decode, which doesn’t make them very safe. On the other hand, keypadlocks can be more secure. This type of padlock can be re-keyable and non-re-keyable and can also be key retaining or not. Key retaining means you cannot remove the key while the lock is open.

Deadbolt Locks

A deadbolt lock replacement can secure external doors, and they are also very cost-effective and have a few more options than padlocks. This locking mechanism works through a cylinder that runs directly through your door and has a keyhole outside. Deadbolts come in three designs: single, double, and lockable thumb turn.

Single-cylinder deadbolts are very common in American households. These common locks have a key cylinder on the outside, and a thumb turns on the inside to open or close the latch. The weakness of these deadbolts is that they can open the door using the thumb turn if someone gets access to the interior.

The double-cylinder deadbolt uses a key cylinder inside and outside to solve the single cylinders issue. The disadvantage of double-cylinder deadbolts is they require a key to open the door from the inside, which can be a problem if an emergency occurs.

The thumb turn provides maximum security and flexibility, a hybrid between the single and the double deadbolt.  It means it has a thumb turn on the inside that functions as a single-cylinder lock but can be locked using a key, so it cannot lock or unlock the door.

You can leave a thumb-turn lock unlocked in a home while there are people in the house, and it will work as a single-door lock. But when the house is empty, this latch can be locked. Thus, the lock won’t be unlocked even if anyone can access the door from the inside.

The Common Combination Locks

Combination locks need a sequence of numbers, letters, or symbols into a rotating dial pad to open. These bolts come in a single dial pad, multiple dials, and the most advanced ones with an electronic pad. Combination locks are often used for padlocks, school lockers, and safes.

The Common Cam Locks

Cam locks provide simple security lock solutions, and you can find them in the market for fewer than 20 dollars. Cam locks come in a cylindrical base with a keyhole and a piece known as the cam. The functionality is straightforward; insert the key in the keyhole and turn it, and the cam rotates or counters clockwise. There are many cam options, but straight and hooked are the most common.

You can find cam lock replacements in cabinets, furniture, and smaller compartments, which may come in different colors and styles. Cam locks are easier to install than most locks, but they won’t secure valuables highly due to their simple design.


3 Reasons to Install the Common Deadbolt Lock

A deadbolt lock is a type of lock that can only be opened by rotating the key or knob, unlike a spring bolt lock which can be opened by applying force to the bolt. Deadbolt locks are more secure and resistant to break-ins than spring bolt locks, offering several advantages for homeowners and renters. Here are three reasons to install the deadbolt lock on your doors.


  1. Enhanced Security. A pick-resistant deadbolt lock provides higher security than a spring bolt lock because it cannot be easily picked, bumped, or forced open. A deadbolt lock requires a key or a code to unlock it, meaning only authorized people can access your home. A deadbolt lock also prevents intruders from using a credit card or a knife to slide the bolt open, a common technique for spring bolt locks.


  1. Increased Durability. A deadbolt lock is more durable and long-lasting than a spring bolt lock because it does not rely on springs or other moving parts that can wear out over time. A deadbolt lock is a solid metal that withstand repeated use and harsh weather conditions. A deadbolt lock also does not need to be replaced as often as a spring bolt lock, which can save you money and hassle in the long run.


  1. Improved Convenience. A deadbolt lock is more convenient and user-friendly than a spring bolt lock because it offers more options and features for locking and unlocking your doors. For example, choose from different deadbolt locks, such as single-cylinder, double-cylinder, or keyless entry, depending on your needs. Also, install a smart deadbolt lock you can control remotely via your smartphone, making your life easier and safer.


Can a Locksmith Work All Common Locks? 


This is a question that many people ask when they need to hire a professional locksmith near me to help them with their security needs. The answer is not straightforward, as different locks require different operating skills and tools. 


However, most locksmiths are trained and experienced in working with a variety of common locks, such as deadbolts, padlocks, knob locks, lever locks, and cylinder locks. Some locksmiths may also specialize in certain areas, such as automotive, residential, or commercial locksmithing. 


Therefore, finding a locksmith who can handle the specific type of lock you need is important.
