Hello from 24/7 Locksmith in Roslyn, New York

If you've ever moved into a new home, lost your keys, or simply wanted an additional layer of security, you've likely heard the term 'rekeying.' 

But what is rekeying a lock? How does rekeying work? We're here to answer those questions and more in this blog post!

Understanding Rekeying

To get to grips with rekeying, we first need to understand the basics of how a lock works.

The Structure of a Lock

In a conventional lock, you'll find a series of pins of different lengths. These pins match up to the unique pattern of your key. Inserting the key raises the pins to their correct height, allowing the lock to open.

So, What Does It Mean to Rekey a Lock?

Rekeying a lock means changing the internal mechanism of the lock so it can be operated by a new key. This is done by changing the configuration of the pins inside the lock. Your old key becomes obsolete and is replaced by a new one.

When is Rekeying Necessary?

Rekeying is an affordable solution for enhancing security when you're not sure who else might have keys to your property. It's an excellent option if you've recently moved, lost a set of keys, or had to let go of a staff member who had access to your premises.

Rekeying vs. Changing Locks

Knowing the difference between rekeying and changing locks is crucial when it comes to maintaining your property's security.

Defining Rekey

Rekeying alters your current lock so that it can be operated by a different key. A professional locksmith can do this without needing to remove the entire lock, making it a fast and cost-effective security solution.

What is a Lock Change?

Changing locks involves completely replacing the old lock with a new one. While this is more expensive and time-consuming, it's sometimes necessary. For instance, if your lock is damaged, or you want to upgrade to a more secure model.

Which to Choose: Rekey vs Lock Change

If your lock is functioning correctly, and you're satisfied with its level of security, rekeying is a sensible, budget-friendly choice. However, if you're looking to upgrade the aesthetic or security features of your lock, a complete lock change may be necessary.

How Does Rekeying Work?

Rekeying might sound like a complex procedure, but it's actually pretty straightforward when executed by a professional.

The Process of Rekeying

A locksmith begins by removing the lock from your door. Next, they disassemble the lock cylinder and discard the old pins. They then insert new pins that correspond with the new key. Once the lock is reassembled and reinstalled, only the new key can unlock it.

Why You Need a Professional

While rekeying might sound simple enough, it requires specialized tools and a detailed understanding of lock mechanisms. Always hire a professional locksmith to ensure your property's security isn't compromised.

Wrapping Up: The Value of Rekeying

Rekeying offers a straightforward, economical method of enhancing your property's security without the need for a total lock change. 

Whether you're moving into a new home, misplaced a key, or had a change in staffing, rekeying can bring you peace of mind.
