The Benefits of Rekeying vs. Replacing Your Locks

When it comes to securing your home or business, one of the first things you might think about is your locks. Whether you’ve just moved into a new property, lost your keys, or need to boost your security, you have a couple of options: rekeying or replacing your locks. But which one is the better choice for your situation?



The main difference is simple. Rekeying involves changing the lock’s internal mechanism so old keys no longer work, while replacing locks means putting in an entirely new set of hardware. Both options offer security benefits, but they’re suited to different needs.


In this article, we’ll explore both options in detail. Understanding when to choose rekeying or lock replacement will help you make the best decision, save money, and ensure your property stays safe.


What is Rekeying?


Rekeying is a simple process that changes the internal mechanism of a lock. When a lock is rekeyed, the old keys no longer work. Instead, new keys are made to match the updated lock. This is usually done by a locksmith, who takes apart the lock and adjusts its pins.


Rekeying is a good choice when you want to maintain your current locks but need to make sure old keys can’t open them. It’s an easy way to secure your home or business without having to replace everything. Plus, it’s often more affordable than replacing the entire lock.


What Does Replacing Your Locks Involve?


Replacing locks means getting rid of the old hardware and putting in a completely new set of locks. This process involves removing the old lock and installing a brand-new one. Depending on the type of lock you choose, this could include upgrading to a more secure or modern option.



This option is best if your current locks are damaged, outdated, or if you simply want to upgrade your security. Replacing locks can also be a good choice if you want to add features like smart locks or high-security systems. While it’s a more expensive option compared to rekeying, it may provide better peace of mind if you’re looking to enhance your overall security.


Rekeying vs. Replacing: Quick Comparison



When deciding between rekeying and replacing locks, it helps to compare both options side by side. Here’s a quick look at how they differ:


Cost


Rekeying is generally the more affordable option. Since it doesn’t require replacing the entire lock, the cost of rekeying is much lower than replacing locks. If you're on a tight budget and just need to secure your property quickly, rekeying might be the right choice.


Replacing locks is more expensive because you’re buying new hardware and paying for installation. However, if your locks are old or damaged, replacing them might be necessary to ensure proper security.


Time


Rekeying takes less time. A skilled locksmith can rekey your locks in just a short while, sometimes within an hour or two, depending on how many locks need to be rekeyed.


Replacing locks takes more time because it involves removing the old lock and installing a new one. Depending on the number of locks you need replaced, this can take longer.


Security


Both rekeying and replacing locks offer solid security, but in different ways. Rekeying makes sure that old keys won’t work anymore, which is great if you’re worried about lost or stolen keys.


Replacing locks, on the other hand, can give you the opportunity to upgrade to a more secure lock system, especially if your old locks are outdated. For those looking for the latest in security technology, like smart locks or high-security deadbolts, replacing locks is the way to go.


Convenience


Rekeying is often the more convenient choice when you don’t need to change the look or style of your locks. It’s quick and cost-effective, and you don’t have to worry about fitting new locks into existing doors.


Replacing locks might be a better choice if your current locks are beyond repair or if you want a new look for your doors. However, it’s a bigger commitment in terms of time and money.


When to Choose Rekeying



Rekeying is a great option in several situations:


  • Lost or Stolen Keys: If you’ve lost your keys or think someone might have stolen them, rekeying ensures no one else can access your property.
  • Moving into a New Home: When you move into a new house or apartment, you can’t be sure who might still have a copy of the keys. Rekeying gives you peace of mind knowing that only you have access.
  • Multiple Tenants: If you’re managing a rental property or shared space, rekeying helps you control who has access at any given time.
  • Budget-Friendly: If you want to save money while still improving security, rekeying is the most affordable choice.

Rekeying works best when you want to stick with your current locks but need to change who can open them. It’s fast, easy, and cost-effective.


When to Choose Lock Replacement



Replacing locks is the best option if:


  • Old or Damaged Locks: If your locks are worn out, broken, or no longer functioning properly, replacing them is the right choice. Old locks are easier to pick or bypass, so upgrading to something new offers better protection.
  • Upgrading Security: If you want to enhance the security of your home or business, replacing locks with newer, more advanced systems, like smart locks or high-security deadbolts, can make a significant difference.
  • Need a New Look or Function: If you're looking to change the appearance or functionality of your locks (for example, installing a smart lock system), replacing them is the way to go.

Lock replacement is the best choice when your current locks no longer meet your security needs or when you want to add modern features to your property. While more costly, the added benefits might make it worth the investment.


How to Make the Right Choice for Your Home or Business



Choosing between rekeying and replacing your locks depends on your unique situation. Here are some simple guidelines to help you decide:


  • Consider Your Budget: If you’re looking for a quick, affordable solution, rekeying is the way to go. However, if you’re willing to invest more for better security or modern features, replacing your locks might be the better option.
  • Evaluate the Condition of Your Locks: If your locks are old, worn out, or broken, replacing them will give you a fresh start with better security. On the other hand, if your locks are still in good condition, but you just need to change the key access, rekeying will do the job.
  • Think About Your Security Needs: If you need to upgrade your security to include things like smart locks or advanced deadbolts, replacing your locks is the right choice. However, if your primary concern is controlling access and preventing unauthorized key copies, rekeying is an effective, low-cost solution.

By carefully considering these factors, you can choose the option that best fits your needs, whether that’s a simple rekeying or a full lock replacement.


Why You Should Hire a Professional Locksmith



While rekeying and lock replacement are tasks that seem simple, hiring a professional locksmith is always the safest option. Here’s why:


  • Expert Advice: A professional locksmith can assess your situation and recommend the best solution for your needs. Whether it’s rekeying a few locks or replacing them entirely, they’ll ensure the job is done right.
  • Proper Installation: When you replace your locks, a professional locksmith ensures the new locks are installed correctly and securely. Improper installation can leave your property vulnerable to break-ins.
  • Time and Convenience: A locksmith has the tools and expertise to get the job done quickly and efficiently, saving you time and hassle.

Hiring a trusted locksmith gives you peace of mind knowing your locks are in good hands and your security is a top priority.


Conclusion


Whether you choose rekeying or replacing your locks, both options offer solid security benefits. Rekeying is a fast, budget-friendly solution for changing access, while lock replacement is ideal for upgrading security or replacing old, damaged locks. Consider your needs, budget, and security goals to make the best choice.

Emergency Locksmith vs DIY Fixes: When to Call the Pros in Murray

November 16, 2025
Locked Out or Locked In? Let’s Talk About What Really Works It always happens at the worst possible moment—you’re running late, juggling groceries, and realize your keys are sitting on the car seat or kitchen counter. The internet is full of quick DIY lock “hacks,” but the question is: should you try them? For homeowners and drivers in Murray, UT , it’s important to know when a do-it-yourself approach can solve the problem and when you need an emergency locksmith who can handle the job safely, quickly, and without damaging your property. This guide breaks down the truth about DIY lock fixes, explains how professional locksmiths handle emergencies, and helps you make smart, stress-free decisions the next time you’re locked out. The Real Difference Between DIY and Professional Locksmith Help People often assume locksmiths are just “key openers,” but modern locksmithing combines mechanical skill, electronics expertise, and security training . Before deciding whether to handle a problem yourself, it’s worth understanding what makes professional service different. What an Emergency Locksmith Does A licensed emergency locksmith offers more than just door unlocking. They provide 24/7 assistance for a wide range of lock and key issues, including: Vehicle lockouts and key extraction Residential or office lockouts Rekeying after lost or stolen keys Broken key removal Ignition and smart lock repair Emergency lock replacement after break-ins Their goal is to get you safely inside while protecting the integrity of your door or ignition system. Why DIY Fixes Aren’t Always the Best Idea DIY methods—like using a coat hanger, credit card, or screwdriver—can cause more harm than good. Common risks include: Damaging the lock mechanism , making it harder or impossible to repair later. Scratching doors or frames , which can void warranties or lower resale value. Triggering car alarms or security systems . Breaking keys inside the cylinder , doubling your repair costs. In short, what seems like a clever internet trick can turn a small inconvenience into a major expense. How to Know When to Call a Professional Not every situation requires emergency help—but many do. Below are common scenarios Murray residents face, and the smartest response for each. 1. You’re Locked Out of Your Home If you’ve simply left your keys inside and there’s another accessible entry point (like a trusted neighbor with a spare), you may not need immediate locksmith help. However, if you’re locked out late at night, during bad weather, or if there’s no safe way inside, call a 24-hour locksmith. They can unlock doors without drilling or breaking hardware. 2. Your Key Snaps Inside the Lock Trying to pull out the broken piece with pliers or tweezers can push it deeper. A locksmith has extraction tools designed to remove fragments safely and rekey the cylinder if necessary. 3. Your Car Key Fob Stops Working Replacing a fob battery is a simple DIY fix—but if the problem is with programming or a broken transponder chip, it’s time for a professional. Murray’s mobile locksmiths can reprogram or replace car keys on-site, saving you a dealership trip. 4. After a Break-In or Attempted Theft If your locks or doorframes are damaged, don’t attempt repairs yourself. A locksmith can assess structural integrity, install new hardware, and restore your home’s security right away. 5. Frozen or Jammed Locks in Winter Utah winters can freeze locks solid. Avoid pouring hot water—it may work briefly, but refreezes quickly and causes corrosion. Locksmiths use proper de-icing compounds and lubricants to protect internal mechanisms. 6. You’ve Lost a Key and Can’t Be Sure Who Has It In this situation, rekeying is safer than simple duplication. A locksmith can change the pins so old keys no longer work—an essential step for home or business safety. When DIY Is Fine (and When It Isn’t) Some maintenance tasks can safely be done at home with the right tools and care. Knowing the line between safe DIY and risky repair can save you stress. DIY That’s Usually Safe: Cleaning dirt from keyways with compressed air Applying graphite or silicone lubricant to sticky locks Replacing worn key fob batteries Testing spare keys periodically DIY to Avoid: Forcing jammed keys Trying to pick or bump locks Removing car door panels to access locks Using online “slim-jim” tools without training If it involves metal tools inside the mechanism or electronic components, it’s best to leave it to professionals. The Murray Advantage: Why Local Expertise Matters In a city like Murray, UT , where weather swings from freezing winters to hot summers, locks take a beating. Local locksmiths understand the climate-related issues that affect lock performance—like thermal expansion, moisture, and salt corrosion. A nearby emergency locksmith can: Arrive within minutes for local lockouts. Bring specialized tools suited for Utah’s common lock brands. Offer honest pricing without hidden travel fees. Handle residential, automotive, and commercial needs on-site. That combination of expertise and proximity makes a huge difference when you’re stuck outside your home or vehicle. Common Questions About Emergency Locksmiths Can a locksmith really unlock my car without damage? Yes. Professionals use non-destructive tools like air wedges and long-reach devices designed specifically for modern vehicles. How much does an emergency locksmith cost in Murray? It varies by time and complexity, but most local locksmiths offer transparent pricing before starting the job. Late-night or weekend services may carry small surcharges.

Many modern locksmiths specialize in smart lock setup, Wi-Fi integration, and troubleshooting. Choosing Safety (and Sanity) Over Stress It’s tempting to handle lock issues yourself, especially when you’re in a rush—but one wrong move can cost more in the long run. DIY methods might open a door once, but they often damage locks or compromise security. A professional locksmith brings not just tools, but training, efficiency, and accountability . Whether you’re locked out of your car, home, or office in Murray, having a reliable expert on call ensures safety, speed, and peace of mind.
