Rekeying vs. Replacing Your Locks: Which Option is Right for You?
/in Locksmith Help /by Alexa UrbinaYour locks are the first line of defense in protecting your home or business. But over time, you may encounter situations that prompt a change. Maybe you’ve lost a key, moved into a new home, or experienced a security breach. When it comes to addressing these concerns, two common choices emerge: rekeying your existing locks or replacing them entirely. Understanding the differences, benefits, and costs of each option can help you decide which path best aligns with your needs.
What Does Rekeying Involve?
Definition: Rekeying a lock means adjusting the internal components—specifically the pins and tumblers—so the lock can be operated by a new key. It does not replace the lock itself; instead, it alters the locking mechanism inside the existing hardware.
Process: A locksmith will remove the lock cylinder, rearrange the pins, and issue you a new key that matches the updated configuration. The old keys will no longer work, effectively giving you control over who has access without changing the hardware on your door.
Pros of Rekeying:
More Affordable: Rekeying typically costs less than installing all new locks since you’re not paying for new hardware.- Maintains Current Hardware: If you like your existing lock fixtures or recently invested in quality locks, rekeying keeps that investment intact while updating security.
- Quick and Convenient: Rekeying is usually a faster process than full replacement and can often be done on-site in a single visit.
When to Consider Rekeying:
- You’ve Moved into a New Home: After taking ownership of a new home, rekeying ensures that former occupants, contractors, or real estate agents can no longer gain entry.
- Lost or Stolen Keys: If you’ve lost your keys or suspect they’ve been stolen, rekeying is a quick and cost-effective way to restore security.
- Consolidating Keys: If you have multiple locks that require different keys, a locksmith may be able to rekey them to work with a single master key—simplifying your life.
What Does Rekeying Involve?
Definition: Replacing locks means removing your existing lock hardware—knobs, handles, deadbolts—and installing entirely new units.
Process: A locksmith or qualified installer removes the old lock and fits a new one in its place. This often involves ensuring the door frame, strike plate, and bolt align properly. Upgrading to high-security or smart locks is also simpler during a full replacement.
When to Consider Replacing Locks:
- Old or Damaged Hardware: If your locks are outdated, heavily worn, or frequently malfunctioning, replacement ensures reliable operation and enhanced security.
- Upgrading Security Features: If you want to invest in high-security locks, electronic keypads, or smart lock technology, a full replacement is often the best route.
- Aesthetic Changes: If you’re renovating your home or office and want modern fixtures that match your new décor, replacing locks can deliver both style and security.
Pros of Replacing Locks:
Increased Security Options: With a lock replacement, you have the freedom to choose from a wide range of modern lock types, finishes, and advanced features.- Enhanced Durability: New locks come with fresh components that are less prone to wear and tear, ensuring smooth operation for years to come.
- Complete Peace of Mind: Knowing you have brand-new hardware provides confidence that your door’s first layer of security is up to current standards.

4. Aesthetics and Technology

Common Scenarios
Scenario 1: Just Moved into a New Home
- Recommendation: Rekey the existing locks for peace of mind and cost-effectiveness.
Scenario 2: Worn-Out Deadbolt That Sticks Constantly
- Recommendation: Replace the lock with a higher-quality or modern lock to improve functionality and security.
Scenario 3: Desire for a Smarter Entry System
- Recommendation: Replace your existing locks with a smart lock system that offers keyless entry, remote control via smartphone, or voice command integration.
Scenario 4: Lost Your Keys Recently
- Recommendation: Rekey your locks to prevent unauthorized access by anyone who might find the old keys.

When in doubt, seek professional guidance. A licensed, insured locksmith can assess the condition of your locks, discuss your security goals, and recommend the best solution—whether that’s rekeying, replacing, or even a combination of both. With professional expertise on your side, you can make an informed decision that aligns with your budget, taste, and long-term peace of mind.

Choosing between rekeying and replacing your locks doesn’t have to be a daunting decision. By considering factors like cost, desired security level, and overall condition of your current hardware, you can find the best solution for your home or business.

Understanding the most frequent scams is the first step in avoiding them. Here are some of the common tactics used by dishonest locksmiths:
In Texas, locksmiths are required to have a valid license to operate. Ask for the locksmith’s license number, and verify it through the Texas Department of Public Safety’s website. Licensed locksmiths are trained, insured, and accountable, making them a safer choice.
Before the locksmith begins any work, request a written estimate. This estimate should include all potential charges, such as service fees, labor, and any parts required. If the locksmith refuses to provide an estimate or claims that the cost is “to be determined,” it’s best to look for another provider.
When the locksmith arrives, ask to see their ID and license. A legitimate locksmith will carry both. You can also look for branded equipment, a uniform, and a vehicle with the company’s logo. This can help you ensure the locksmith is genuinely affiliated with the company you called.
If you feel something is off during your interaction with a locksmith, trust your instincts. Here’s what you can do:
To avoid scams, it’s best to take a proactive approach in finding a reputable locksmith. Here’s how:
Several issues can cause a key fob to malfunction. Here are the most common:
A dead or weak battery is one of the most common reasons for key fob issues. Most key fobs use small, coin-shaped batteries, such as CR2032 or CR2025.
Preventing key fob issues is easier when you follow a few maintenance practices:
If none of the above solutions work, it may be time to consult a professional locksmith or dealership. A locksmith specializing in automotive services can often diagnose and repair key fob issues more affordably than a dealership. Here are some instances when you should consider professional help:
A smart lock is an electronic lock that allows you to control access to your home using a smartphone, keypad, fingerprint reader, or voice command. Unlike traditional locks that rely on physical keys, smart locks use wireless communication—typically Bluetooth, Wi-Fi, or Z-Wave—to connect to your devices, enabling remote access and control.
Smart locks offer significant advantages over traditional locks:
When choosing a smart lock, consider the following features to ensure you get the best security for your home:
Installing a smart lock is generally straightforward, especially if you choose one compatible with standard deadbolts. Most smart locks come with easy-to-follow instructions, but professional installation can be helpful if you’re unfamiliar with electronic devices.

To make the most of your smart lock and ensure your home remains secure, follow these additional tips:
Smart locks are a great investment for homeowners who want both convenience and security. However, like any technology, they require regular maintenance, such as battery replacement and software updates. If you’re comfortable with these requirements and want more control over your home’s security, a smart lock can be a fantastic addition to your setup.
Check All Doors and Windows: Sometimes, a door or window might be unlocked, allowing you an easy way back in.
Reach Out for Spare Keys: If you’ve given a spare key to a trusted friend, neighbor, or family member, contact them for help.
Credit Card Method for Simple Locks: If you’re locked out of a door with a simple latch, you can try sliding a plastic card between the door and the frame to push the latch open. This method typically only works with certain types of spring-latch locks and should be done gently to avoid damaging the lock.
Call a Professional Locksmith: If you’re unable to get in using DIY methods or if you’re worried about damaging the lock, it’s best to call a licensed locksmith.
Make a Spare Key: Consider having a spare key made and giving it to someone you trust, or keeping it in a secure, accessible place.

Losing keys is incredibly common, especially in a bustling city where it’s easy to get distracted. While losing keys can be frustrating and worrisome, there are ways to resolve it without too much hassle:
Keys undergo regular wear and tear, and over time, they can weaken and even break. This can happen when you try to force a worn-out key into the lock or if the key gets bent or damaged.
Modern vehicles often use key fobs, which are convenient but also prone to issues like battery drain, electronic malfunctions, or even desynchronization with the vehicle’s locking system.
Smart keys and transponders add an extra layer of security to vehicles but can also face connectivity issues, electronic malfunctions, or desynchronization problems. These issues can prevent you from unlocking or starting your car.
Getting locked out of your car is frustrating, especially if you’re in a rush or in an unfamiliar part of town. Lockouts can happen when you leave your keys inside, or if there’s an issue with the locking mechanism itself.
Ignition lock issues are another common problem. Sometimes, the key may not turn in the ignition or could get stuck, which may indicate a problem with the ignition cylinder.
Handling car lock issues on your own can be risky, as it may lead to further damage or security vulnerabilities. Here are a few reasons to rely on a licensed locksmith:
