Moving into a new home is an exciting moment. The boxes, the fresh start, the sense of ownership—it all feels like a clean slate. But while we often focus on painting walls or setting up furniture, one of the most important steps is often overlooked: securing the locks. Rekeying your locks after moving is not just a precaution—it’s essential for safety, peace of mind, and long-term security.
Understanding What Rekeying Actually Means
Rekeying is not the same as replacing locks. When we rekey a lock, we keep the hardware but change the internal pins so that the old keys no longer work. A new key is then created to match the updated mechanism. This simple process ensures that anyone who previously had access to the property—whether a previous owner, tenant, or contractor—can no longer use their old key.
Unlike replacing locks, rekeying is faster and more affordable because we don’t have to remove or install new hardware. It’s a professional adjustment that gives you brand-new control over who can enter your home.
The Hidden Risk of Old Keys
When we move into a new home, we rarely know how many copies of the old keys exist. Real estate agents, cleaning services, maintenance workers, or relatives of the previous owner may all have had access at some point. Even if the seller hands over what they say is the only set, there’s no way to verify it.
Old keys represent an invisible risk. Anyone with a copy could potentially walk into your home without signs of forced entry. Rekeying eliminates this uncertainty, ensuring that only your family’s keys open those doors.
Rekeying Protects More Than Just Your Front Door
People often assume rekeying applies only to the main entrance. In reality, it’s just as important for every exterior lock, including side doors, garage entries, and backyard gates. If your new home has a mailbox or shed with its own lock, those should be rekeyed too.
We sometimes forget that thieves or trespassers don’t always use the front door. A side or back entry that shares the same key system as the previous owner’s could be the weakest point in your home’s security. Rekeying ensures every entry point is under your control, creating a single, unified key system for convenience and safety.
Rekeying vs. Replacing: Choosing the Right Option
Not every situation requires full lock replacement. Rekeying is ideal when the locks are in good condition and you simply need to change who can access them. Replacing, on the other hand, becomes necessary if the locks are old, damaged, or incompatible with modern keying systems.
The main difference lies in cost and purpose. Rekeying is about security management, while replacing is about hardware improvement. A professional can inspect your locks and advise whether rekeying will meet your security goals.

When to Rekey Beyond a Move
While moving is the most obvious time to rekey, it’s not the only reason. There are several other scenarios where rekeying makes sense. If you’ve recently lost a key, loaned one to a contractor, or had a roommate move out, it’s smart to change the keys.
Rekeying also helps when your keys start sticking or turning roughly inside the lock. This may indicate internal wear that can be corrected during the rekeying process. By adjusting the pins and realigning components, a professional can restore smooth operation without replacing the entire unit.
In rental properties, landlords often rekey between tenants to protect privacy and liability. Homeowners can take the same approach to maintain control over access at all times.
How Rekeying Enhances Everyday Security
Beyond preventing unauthorized entry, rekeying can make your daily life more convenient. Many homes have multiple doors requiring separate keys, which can quickly become frustrating. Rekeying allows a locksmith to match all the locks to a single key, giving you simpler access without reducing security.
This one-key solution also reduces wear on the locks because you’re less likely to use the wrong key or force a fit. Over time, it helps maintain the longevity of your locks while improving your home’s safety and comfort.
Preparing Your Locks for Rekeying
Before scheduling a rekeying service, take a quick look at the condition of your locks. Make sure they operate smoothly and that there’s no rust, cracking, or loose components. Clean the keyholes gently with a dry cloth to remove any visible debris.
If your locks are significantly worn or outdated, mention it to the locksmith before the appointment. They may recommend upgrading the cylinders during rekeying to improve security and performance.
Also consider whether you’d like to rekey all doors to one master key or maintain separate keys for different areas, such as a detached garage or office. Knowing your preferences ahead of time saves both time and confusion during the process.
Rekeying and Smart Locks
Even homes equipped with smart locks can benefit from rekeying. Some smart locks still rely on a physical key backup for emergencies. If that mechanical key is unchanged after moving, the risk remains the same.
A professional locksmith can rekey the backup cylinder to ensure that only your new keys work, integrating digital and physical security into one system. This step keeps both the electronic and mechanical sides of your home equally protected.
Why Timing Matters
Many people put off rekeying, assuming it can wait until after the move settles. But during those first few days, your home is often full of unpacked items, expensive electronics, and little oversight. This makes it the most vulnerable period.
Rekeying immediately after getting the keys ensures you start with full control from day one. You won’t need to worry about who might still have access, allowing you to focus on the positive aspects of your new home.
The Peace of Mind Factor
Beyond practical protection, rekeying gives you something just as valuable: peace of mind. Knowing that every lock and key combination is brand new and under your control brings comfort that no alarm system can replace.
Security is not only about preventing crime—it’s about confidence. Rekeying your locks is a small action with a major psychological impact. It removes uncertainty and helps you truly settle into your new environment without hesitation.
How to Know You Can Trust a Locksmith
When choosing someone to rekey your home, reliability matters as much as skill. Look for professionals with verified experience and local presence. Ask about their licensing, insurance, and tools used for precision work.
Rekeying might sound simple, but doing it incorrectly can cause long-term lock issues. A good locksmith ensures your locks function smoothly and remain durable. The key turns easily, the latch secures properly, and you can lock or unlock without force.

Rekeying As Preventive Maintenance
Home security isn’t only about responding to problems—it’s about preventing them. Rekeying is a proactive habit that reduces risk before anything happens. Just like replacing smoke detector batteries or servicing your furnace, it should be part of your home maintenance routine.
Performing a rekey every few years, especially after significant life changes like tenants moving out or renovations involving outside contractors, keeps your property’s access tightly controlled. It’s an easy step that strengthens your security without major expense or disruption.
Tips for Keeping Track of New Keys
After rekeying, it’s important to manage your new keys responsibly. Label spare keys discreetly without writing your address or unit number. Store backups in a secure, private place instead of leaving them under doormats or in obvious outdoor spots.
If you want emergency access for family or neighbors, consider using a lockbox with a unique combination rather than handing out multiple spare keys. This method gives you flexibility while maintaining control over who can enter.
Rekeying for Businesses and Rentals
Though we often discuss rekeying in the context of moving homes, the same principle applies to commercial and rental properties. Offices, retail spaces, and apartment units see frequent staff and tenant turnover. Each change increases the number of people who might still possess a copy of the key.
Business owners can schedule regular rekeying to maintain confidentiality and protect assets. For landlords, it’s an easy way to meet legal and ethical responsibilities for tenant safety. Rekeying ensures each new occupant begins with a clean security slate.
Cost vs. Value
Many people delay rekeying out of concern for cost, assuming it’s expensive. In reality, rekeying is one of the most cost-effective security steps available. The price depends on the number of locks and complexity of the key system, but compared to full replacements, it’s minimal.
The value, however, is immense. You’re not just paying for a mechanical change—you’re buying peace of mind, control, and protection for your household. Considering the potential risks of unauthorized access, the investment is well worth it.
Common Mistakes to Avoid
One common mistake is assuming all locks can be rekeyed. Some cheaper models or older systems may not support rekeying or may require new cylinders. Another error is attempting to rekey without professional tools, which can damage the lock or leave it insecure.
Avoid rekeying just one door and leaving others unchanged. Security is only as strong as the weakest point. Always address all exterior locks together so no outdated key remains in use.
How Rekeying Fits Into a Complete Security Plan
Rekeying is only one part of home security, but it’s the foundation. Once the locks are secured, consider complementary steps like updating door hardware, adding motion lights, or installing a video doorbell.
However, these measures only work if you control physical access first. Without rekeying, even the most advanced system can be compromised by a simple old key. Starting with the basics ensures every other security layer functions effectively.
