When it comes to securing your home or business, one of the key decisions you’ll face is whether to rekey your locks or replace them entirely. Both options can help improve your security, but they come with different costs, time frames, and benefits. In this post, we’ll explore why rekeying locks is often a smarter, more cost-effective choice than replacing them. Let’s dive in!
Introduction to Rekeying vs. Replacing Locks
What is Rekeying?
Rekeying a lock involves changing the internal pins and springs inside the lock so that it works with a new key, but the lock itself remains the same. Essentially, the old keys will no longer work, but your existing hardware stays in place. Rekeying is a popular choice when you need to increase security without the hassle and cost of replacing the whole lock system.
What is Lock Replacement?
On the other hand, replacing a lock means removing the old lock and installing a completely new one. This process involves buying new locks, which can be more expensive and time-consuming. While replacing locks ensures complete security, it’s not always necessary, especially if the locks are still in good condition.

Five Key Reasons to Choose Rekeying Locks Over Replacing Them
Rekeying offers several advantages that make it a more practical choice in many situations. Here are the top five reasons why rekeying locks is often the better option:
1. Cost-Effective Solution
One of the main reasons to rekey your locks instead of replacing them is the significant cost savings. Rekeying a lock is usually far less expensive than buying and installing a new one. With rekeying, you’re only paying for the adjustment to the internal mechanism, not an entirely new lockset. This makes it an excellent choice for those on a budget or when you have multiple locks to update.
2. Quick and Convenient Process
Rekeying is a quick process, often taking less than an hour to complete, depending on how many locks need rekeying. Unlike replacing locks, which may involve removing old hardware, purchasing new locks, and possibly making follow-up appointments, rekeying can usually be done in a single visit. If you’re in need of a fast solution, rekeying offers the convenience of speedy service without the disruption of full lock replacement.
3. Maintains Existing Hardware
If you’re happy with the quality and appearance of your current locks, rekeying allows you to maintain the same hardware. This is particularly useful if your locks are high-quality or have a style you prefer, but you’re concerned about security. Rather than replacing them entirely, rekeying offers an affordable way to upgrade your security without changing your entire lock system.
4. Enhanced Security
Rekeying provides the same level of security as replacing locks, especially in situations like moving into a new home, losing your keys, or when you’re concerned about unauthorised access. If you’ve misplaced your keys or suspect someone has made copies, rekeying ensures that only the new key will work, leaving the old keys useless. It gives you peace of mind knowing your property is secure, without the need for replacing the locks.
5. Environmentally Friendly
Rekeying is also an eco-friendlier option compared to lock replacement. When you replace a lock, the old hardware often ends up in a landfill. By rekeying, you’re reducing waste and keeping your existing locks intact. It’s a simple way to contribute to sustainability while maintaining your security.
When to Consider Rekeying Instead of Replacing
While rekeying offers many benefits, there are certain situations when replacing a lock might be the better choice. Here are some cases where rekeying might be the ideal option, and others when replacement is necessary:
When to Rekey Your Locks
When You’ve Just Moved into a New Home
If you’ve recently purchased a new home, rekeying your locks is a crucial step in securing your property. You can never be sure how many copies of the old keys are floating around from previous owners or tradespeople. Rekeying ensures that no one else has access to your home and gives you complete control over who holds the keys.
When You’ve Lost Your Keys
If you’ve lost your keys or believe they’ve been stolen, rekeying is the quickest and most affordable solution. Rather than replacing the locks, rekeying makes the old keys useless, offering a quick security upgrade without the hassle or cost of replacing the entire lock system.
When You Want to Control Access
If you’re managing a rental property or have employees who no longer need access, rekeying provides an easy way to restrict access without changing all the locks. It’s ideal for situations where people leave, and you need to ensure they no longer have access without investing in a full lock replacement.
When to Replace Your Locks
When Your Locks Are Damaged
If your locks are old, worn out, or damaged, it’s time to replace them. No amount of rekeying will fix a broken or deteriorating lock. In such cases, replacing the locks will ensure your security is up to standard.

When You Want to Upgrade Your Security System
If you’re looking for an upgrade to your existing locking system, such as installing high-security locks or smart locks, replacing the locks may be necessary. While rekeying will address access control, replacing the locks allows you to incorporate the latest in security technology.
When the Lock Mechanism is Stiff or Hard to Turn
If your lock mechanism is worn or difficult to turn, it could be a sign of internal damage or wear. In these cases, rekeying won’t solve the problem, and replacement may be required to maintain smooth operation.
Rekeying – The Smarter, More Efficient Choice
Rekeying your locks offers a quick and affordable way to enhance your security without the hassle or expense of full replacement. Whether you’ve just moved into a new place, lost your keys, or simply want to boost your home’s safety, rekeying provides faster service, lower costs, and the convenience of keeping your existing hardware, including single and double block locks.
