Should you rekey or change your locks? If you are unsure, you are not alone. This guide breaks down the difference between rekeying and changing locks, helping you make smarter decisions about home security.
According to the FBI, over 1 million burglaries occur in the U.S. every year, many involving unauthorized key access. We will compare the cost of rekeying, the need to change the lock hardware, and when each method fits your situation best.
You will also learn what locksmiths suggest and how to protect your key system from duplication. Let’s decode your options.
What Does It Mean to Rekey a Lock?
Rekeying changes the key that operates your existing lock. Inside every lock are small lock pins that match a specific key cut. A locksmith uses a rekey kit, including tools like a plug follower, to remove the lock cylinder and replace the pins.
Once done, a new key will work, and the old one won’t. The hardware stays the same, just the key access changes. Rekeying a deadbolt lock is common after losing keys or moving into a new place. It’s fast, affordable, and practical for restoring security without full lock replacement.
What Does It Mean to Change a Lock?
Changing a lock means removing the entire hardware and installing a new one. This process replaces the door latch, bolt assembly, and lock housing, often done for security upgrades or when locks are damaged.
With new lock installation, you get fresh keys, updated features, and better aesthetics. This is ideal if your existing system is outdated or if you are switching to a smart deadbolt or an ANSI Grade 1 lock. Unlike rekeying, changing the lock involves full mechanical removal and reinstallation. It’s often the better choice when your priority is top-tier home security.
When Should You Rekey Instead of Changing Locks?
You should rekey when the hardware is intact, but key control is lost. It’s cost-effective and fast, ideal after moving or losing a key. It resets your key system without replacing the entire mechanism.
After Moving into a New Home
When a real estate handover takes place, there is no way to know who still has keys. Rekey new house right after moving to eliminate access by former residents or contractors. It’s a small cost for peace of mind, and you can even set up a master key system for better access control. Many home buyers prioritize rekeying as their first home security step.
When Losing a Key
Lost keys pose a serious home security risk due to potential key duplication. If you are unsure where a key ended up, it’s safer to rekey the lock than gamble on chance.
Locksmiths recommend rekeying as a preventive step to control access. It’s affordable and much quicker than a full lock replacement. After all, peace of mind is worth more than the cost to rekey.
Cost-Effective Security Update
Sometimes, you just want tighter security without breaking the bank. Rekeying offers that. A locksmith quote for rekeying is often lower than for a full hardware change. It’s a quick update that doesn’t compromise safety. Especially for budget-conscious homeowners, the rekey price estimate is attractive compared to buying and installing all-new locks.
When Is It Better to Change the Locks Completely?
If your locks are damaged or outdated, it’s time to replace them. Full lock replacement enhances security and allows you to upgrade features. Changing the lock ensures better durability, aesthetics, and protection against modern threats.
Damaged or Rusty Lock Mechanism
Wear and tear can make locks unreliable. If the lock mechanism sticks, rusts, or breaks, it’s a sign to replace the system. A new lock installation restores smooth function and strong resistance to tampering. Locksmiths often assess the security grade and overall condition before recommending a switch. Prevention is key to long-term security.
Upgrading to Smart Locks
Want app-based access or keypad entry? Then it’s time for a smart lock installation. Today’s smart deadbolts from brands like Yale, Ring, and Nest offer features like remote unlocking and real-time alerts. These often require a complete lock replacement, not just a rekey. Make sure your new lock meets ANSI Grade 1 standards for maximum reliability.
After a Break-In or Attempted Burglary
A break-in leaves your security compromised, even if the intruder failed to enter. The tamper damage or even the attempt itself is enough reason to change your locks. Upgrading to a stronger lock standard helps you regain peace of mind and deter future threats. This isn’t the time for shortcuts; go for full lock replacement.
