Locksmith Terminology: What You Need To Know

Speaking to a Melbourne locksmith doesn’t need to be a daunting task. As a customer, providing the right information over the phone is vital to getting a quick and accurate quote and learning the industry lingo is one of the best ways to ensure your chosen locksmith can complete the job hassle-free.

Below is a list of common phrases used within the locksmith industry.


Rekeying a lock is the process of changing the working key to a new key without having to replace the lock. The old key won\’t work anymore, but you can keep the lock. You can do this by taking apart the lock and replacing certain parts (known as \”tumblers\”, or \”key pins\”) inside. Each series of key pins within your lock corresponds to a particular key pin. By replacing those pins with new ones, you can essentially create a new key that will operate the lock. This is a simple procedure, even though it sounds complicated. If you have the right tools, it shouldn’t take much time.

A current key is required to rekey locks. The only way to rekey a lock is to pick it open if you don\’t have a current key. This can be done by a locksmith, however, additional fees may apply which could make the process more costly than simply replacing the lock.

The security of a lock is not affected by rekeying it. It does not make it safer. The number of pins in a lock is one of its most important factors when it comes to security. The lock will be as secure as ever if the locksmith replaces the 5 old pins with 5 new ones.

It is the service of choice when your locks are not broken, but rather simply want a new key to work your locks, excluding any other existing keys from opening the lock. A common example is if you’ve just moved houses.


Duplication is exactly how it sounds – it’s the process of duplicating or copying an existing key. Your locksmith can make single or multiple copies of a key which can be used as spares, for different family members or for staff at your business.

You will need an existing key to create a duplicate, however, if your key is worn or broken, you will need to check with your locksmith to see if they can duplicate it.

Duplicates are generally cheaper than having a new key created for a lock.


Cuts refers to the physical arrangement of the grooves of the key that engage with the locking mechanism. The cuts shows a locksmith how to create a particular key, to replace a lost key or duplicate a key.


Lock bumping is a lock picking technique for opening a lock using a specially crafted key called a bump key. A bump key must correspond to the lock for it to work correctly.

The process of gaining entry using a bump key is called ‘bumping’.

Strike Plate

A striking plate, sometimes known as a ‘striker’ is a metal plate attached to a door frame with a hole for the bolt of the door. When the door is closed, the bolt extends into the hole in the strike plate and holds the door closed.
