Can cylinder locks be rekeyed? That's a question I get asked a lot as a supplier of cylinder locks. And the answer is a resounding yes! In this blog post, I'll dive into the details of rekeying cylinder locks, why you might want to do it, and how it all works.

First off, let's talk about what a cylinder lock is. A cylinder lock is one of the most common types of locks you'll find on doors, cabinets, and other entry points. It consists of a cylinder (the part where you insert the key) and a set of pins inside the cylinder. When you insert the correct key, the pins align in a specific way, allowing the cylinder to turn and unlock the mechanism.

Now, why would you want to rekey a cylinder lock? There are several good reasons. One of the most common is when you move into a new home or office. You have no idea who else might have copies of the keys to the existing locks. By rekeying the locks, you can ensure that only you and the people you trust have access. Another reason is if you've lost your keys. Instead of replacing the entire lock, rekeying is a more cost - effective solution. You can just change the key combination so that the lost keys no longer work.

So, how does the rekeying process work? Well, it's a bit technical, but I'll break it down for you. A professional locksmith will start by removing the cylinder from the lock. This is usually a straightforward process, but it does require the right tools. Once the cylinder is out, the locksmith will disassemble it. Inside the cylinder, there are a series of pins and springs. The pins come in different lengths, and it's the combination of these lengths that determines which key will work.

The locksmith will then remove the existing pins and replace them with new ones. The new pins are selected based on the new key combination that you want. After the new pins are in place, the locksmith will reassemble the cylinder and test it with the new key. If everything works correctly, the cylinder is then reinstalled back into the lock.

It's important to note that not all cylinder locks are created equal. Some are easier to rekey than others. For example, standard pin - tumbler cylinder locks are relatively easy to rekey. These are the most common type of cylinder locks and are found in many residential and commercial applications. On the other hand, high - security cylinder locks, like those with side - bar or wafer - tumbler mechanisms, can be more challenging to rekey. They often require special tools and more advanced skills.

As a cylinder lock supplier, I've seen firsthand the benefits of rekeying. It's a great way to save money and improve security.

If you're thinking about rekeying your cylinder locks, I recommend hiring a professional locksmith. While it's possible to rekey a lock yourself if you have the right tools and knowledge, it's a delicate process. One wrong move, and you could damage the lock. A professional locksmith has the experience and expertise to do the job right the first time.

In addition to rekeying, there are some other things to consider when it comes to cylinder locks. For example, the quality of the lock matters. A high - quality cylinder lock will be more resistant to picking and bumping, which are common methods used by burglars to open locks. Look for locks that have been tested and certified by independent organizations.

Another thing to think about is the keyway. The keyway is the shape of the slot in the cylinder where the key goes. Different keyways offer different levels of security. Some keyways are more common and easier to pick, while others are more unique and difficult to duplicate.

If you're a business owner, you might also want to consider a master key system. A master key system allows you to have one key that can open multiple locks, while still having individual keys for each lock. This can be very convenient for managing access to different areas of your business.
