What is an IC lock

Interchangeable locks, also called IC locks, are widely used in commercial buildings. However, many people might not be familiar with this mechanism. Today, there are so many different lock types out on the market, so it might be quite hard to keep up with all the inventions. So, we want to tell you more about this particular lock type, how it works and what advantages it has over standard locks.

Basically, this type of lock has an interchangeable core which has the shape of the number 8. As you can suggest from the name, the main feature of this lock is that a cylinder can be easily changed if needed. To complete this process, you'll need a control key. You can either do it yourself or use professional assistance.

How do Interchangeable Core (IC) Locks Work

So, we already defined that an IC lock has a core that can be easily taken out and replaced without removing the entire lock body. These locks are perfect for commercial buildings as they are the most suitable for rekeying.
If you want to remove your lock cylinder, you'll need a special key. First, insert it into your lock, turn this key and take the cylinder out. The process of the new cylinder installation is pretty much the same. Put your key into the new cylinder and turn it. Then, put the new cylinder into the locking mechanism, turn your key in another direction and take it out. It's not complicated, right?
However, if you're not fully confident you can complete this task yourself or you don't have the control key, don't hesitate to use professional commercial locksmith services. It'll take a few minutes for a skilled technician to replace your interchangeable core locks.
