What are Cam Locks?

Cam locks are a type of locking device that is used in more unique applications. They can be seen on home cabinets, office desks, and other furniture – as well as commercial products like vending machines and ATMs. Cam locks work by using a keyed cylinder that operates a flat cam. This cam is a small piece of metal with an angled surface, which slides into the lock body to engage the locking mechanism.

When the cylinder is turned, it moves the cam in and out of its housing, where it interacts with a series of pins (or tumblers) that are set at specific depths. When all of the pins line up perfectly, they unlock and can be opened by turning the key or knob. However, if any pin is out of place, the lock simply won’t open.

The Benefits of Cam Locks

Using cam locks for security has a wide range of unique advantages that make them an attractive option. Some of the most noteworthy include:

  • Ease of Installation- Cam locks are designed to be easy to install and don’t require any special tools or expertise. This makes them ideal for DIY projects and quick replacements in case of emergencies.
  • Variety of Sizes and Shapes- Cam locks come in a wide range of sizes, shapes, and colors to fit any application. They are also available with different key types, so you can choose the one that best suits your needs.
  • Reliability- Cam locks are highly reliable and secure, providing an extra layer of protection against burglary or tampering.
  • Cost-Effective- Cam locks are relatively inexpensive compared to other types of locks, making them a great choice for budget-conscious individuals.

Required Items for Cam Locks

To use a cam lock, you’ll need the following items:

  • A key- Cam locks require a specialized key to operate. This usually comes with the lock when you purchase it, but it can also be purchased separately if needed.
  • Screws or mounting hardware- Depending on the lock type, some cam locks may require screws or other mounting hardware for installation.
  • Threaded inserts- Threaded inserts are required to mount cam locks in furniture or other applications where a hole is needed.

10 Instructions on How Do Cam Locks Work

1. Instalment

Cam Locks Are Installed by Inserting a Key

Cam locks are installed by inserting a key into the cylinder and turning it to the right to engage the cam. Cam locks can be mounted in a variety of materials, including wood, metal, and plastic. While installing the lock, make sure to use the appropriate mounting hardware (e.g., screws or threaded inserts).

2. Key insertion

Once the lock is installed, you can insert the key into the cylinder and turn it to unlock and open the lock. Depending on the type of cam lock you are using, there may be a number of pins inside that must line up perfectly for the lock to open.

3. Pin Alignment

When the key is inserted, it should move a flat cam within the cylinder to align all of the pins inside. If even one pin is out of place, the lock won’t be able to open and must be re-keyed before it can be used again.

4. Turning the knob

Once all of the pins are aligned, you can turn the knob or key to open the lock. Depending on the model, you may need to turn it several times in order to fully engage the locking mechanism.

5. Locking Mechanism

When the lock is opened, a flat cam should slide into place within the cylinder to lock it. This cam prevents the pins from being moved out of alignment by any external force, thus providing an extra layer of security.

6. Re-keying

If you ever need to change the key for your cam lock, this process is relatively simple and can usually be done without a locksmith. Most cam locks come with a re-keying kit that will allow you to easily swap out the old key for a new one.

In order to open the lock again, you’ll need to insert your key and turn it until the flat cam within the cylinder is released. This will allow all of the pins inside to move back into position so that you can turn the knob to open the lock again.

8. Overriding the Lock

If your key is lost or stolen, it’s possible for someone else to override your cam lock by using a specially designed tool called a master key. This type of key will allow them to bypass your lock and gain access, so it’s important to keep it secure and to change the key regularly.

9. Different Key Types

Cam locks come in a variety of different key types, including flat keys, pin tumbler keys and tubular keys. Each type has its own unique advantages and disadvantages, so make sure to select the one that best suits your needs before purchasing a lock.
