Common Mistakes to Avoid When Rekeying Door Locks

April 18, 2023

Introduction

Imagine this situation: you’ve just moved into a new home or taken over a rental property, and you decide to rekey the door locks for added security. It seems simple enough—until you discover that the locks are sticking, the new keys don’t always turn, or someone still has access with an old key.

Rekeying is one of the most practical ways to manage access without replacing all your locks. But there are common mistakes that can compromise your security or cause expensive problems later. This guide explains what rekeying really involves, the pitfalls to watch for, and how to get it done properly the first time.

Understanding What Rekeying Means

Rekeying a lock means changing its internal pins so that only a new key can open it. The outer hardware stays the same, but the internal configuration is adjusted. This process is ideal when you move into a new property, lose a key, or change tenants.


It’s a cost-effective way to maintain security—provided it’s done correctly. If not, you could end up with a faulty lock, a jammed key, or worse, a system that’s still accessible by old keys.

Common Mistakes People Make When Rekeying Locks

Before you begin rekeying or hiring someone to do it, it helps to know what can go wrong. Below are the most common mistakes and how to avoid them.

1. Rekeying old or worn-out locks

Even if a lock looks fine, it might have internal wear that causes trouble once rekeyed. Worn pins, corroded parts, or previous tampering can affect how smoothly a new key turns. In these cases, replacing the lock is often safer and more cost-effective.

2. Using the wrong rekeying kit

Each lock brand has unique parts and measurements. Using a mismatched kit can lead to misaligned pins or a key that doesn’t fit properly. Always check that the rekeying kit matches your lock’s brand and model before starting the process.

3. Overlooking key management

Rekeying won’t improve your security if old keys are still in circulation. Many people forget to collect old keys from tenants, family members, or staff. Keep a record of how many new keys exist and who has them. This simple habit prevents future security risks.

4. Rekeying only the main door

It’s easy to focus on the front door and forget other entry points like the back door, garage, or side access. Leaving one lock unchanged defeats the purpose of rekeying. Before starting, list every entry that uses a key and make sure they’re all included.

5. Attempting a DIY rekey without proper tools

While do-it-yourself kits are available, they often require precision and experience. Losing tiny pins or springs can damage the lock or make it unreliable. If you’re not confident, hiring a qualified locksmith will save time and prevent costly mistakes.

6. Failing to test the new key

After rekeying, always test the new key several times with the door both open and closed. Environmental factors like humidity or door alignment can affect how a lock functions. Testing helps confirm smooth operation before you rely on it.

7. Forgetting future access needs

Many people rekey and then forget to plan for new key copies or future access changes. Keeping a record of who has keys and limiting unnecessary duplication makes managing access easier and safer over time.

Frequently Asked Questions

  • How often should I rekey my locks?

     You should rekey whenever you move into a new property, lose keys, or change who has access. It’s also smart to rekey after renovations or tenant changes.

  • Is rekeying better than replacing locks?

     Rekeying is usually cheaper because you keep the same hardware. However, if the lock is old, damaged, or unreliable, replacing it may be the smarter option.

  • Can I rekey my locks myself?

     You can, but it’s easy to make mistakes without the right tools or training. Professional locksmiths have the experience to complete the job quickly and correctly.

  • Does rekeying make my locks more secure?

     Rekeying improves access control but doesn’t strengthen the lock itself. For better physical security, consider upgrading to high-security hardware.

  • Can one key open all my doors after rekeying?

     Yes, a locksmith can rekey multiple locks to use a single key, provided they’re compatible. This is called “keying alike” and makes access more convenient.

Conclusion

Rekeying is a smart and affordable way to take control of your property’s security. But when done incorrectly, it can cause more problems than it solves. From worn hardware to poor key management, each mistake can affect how well your locks protect your home or business.

By understanding these pitfalls—and working with a professional locksmith when needed—you can enjoy the benefits of rekeying without the hassle or risk. A little attention to detail today can save you a lot of stress later.

Lock Picking Science: How Locksmiths Open Locks Without Damage
May 1, 2025
Have you ever been locked out of your home or car and wondered how a locksmith can open it so easily? Lock picking is a fascinating skill that combines mechanical knowledge, fine motor control, and problem-solving. It's not magic - it's science! Lock picking is the manipulation of a lock's components to open it without using the original key. Professional locksmiths use specialized tools and techniques to unlock doors without causing damage, saving you the cost of replacing expensive locks and hardware. Most people don't think about locks until they're stuck outside looking in. But understanding how locks work and how professionals open them can help you make better security choices and know what to expect when you need emergency lockout services. Understanding Lock Mechanisms Before diving into picking techniques, it's important to understand how locks actually work. Different locks require different approaches, but they all follow mechanical principles. Pin Tumbler Locks: The Most Common Type Pin tumbler locks are what most people have on their homes. These locks use a set of spring-loaded pins that prevent the lock cylinder from turning unless the correct key is inserted. When the right key enters the lock, its unique ridges push the pins up to what's called the shear line , allowing the cylinder to rotate freely and the lock to open. Locksmiths exploit this design by manipulating each pin individually. Wafer Tumbler Locks and How They Work Many cars and office furniture use wafer locks. Instead of pins, these use flat wafers that extend into the lock housing. They're generally less secure than pin tumblers but follow similar principles. Wafer locks are often easier for locksmiths to open, which is why they can get you back into your car relatively quickly during an emergency lockout situation. Lever Locks: An Older But Still Relevant Design Lever locks are common in older buildings and some padlocks. They use a set of lever tumblers that must be raised to precise heights to allow a bolt to slide back. While less common in modern homes, knowing how to work with lever locks is still an essential skill for any Murray locksmith who handles historic properties or antique furniture. Professional Lock Picking Techniques Skilled locksmiths use several techniques to open locks without damage. These methods require practice and precision. Single Pin Picking Method Single pin picking is the most precise technique used by professional locksmiths. It involves: Inserting a tension wrench into the bottom of the keyway to apply slight rotational pressure Using a pick tool to push each pin up to the shear line one at a time Feeling and listening for subtle clicks as each pin sets This method requires significant practice but causes no damage to the lock. Locksmiths in West Jordan and surrounding areas often use this technique when rekeying or servicing high-quality locks. Raking Techniques for Faster Entry When speed matters more than finesse, such as during an emergency lockout, locksmiths might use raking: Insert a rake pick (which has multiple bumps or waves) Apply tension with a wrench Quickly move the rake in and out of the lock This creates vibrations that can cause multiple pins to set simultaneously. It's faster but less reliable than single pin picking, especially on complex locks. Bump Keys and How They Work Bump keys are specially cut keys that can momentarily force all pins above the shear line when struck with the right technique. This method: Works on many pin tumbler locks Requires minimal specialized tools Is fast and effective in trained hands Professional locksmiths in Sandy and Midvale often carry various bump keys for emergency situations, though they typically prefer more controlled methods for everyday work. Tools of the Locksmith Trade A locksmith's toolkit contains specialized instruments designed for non-destructive entry. Essential Lock Picking Tools Every professional locksmith carries: Tension wrenches in various sizes to apply rotational pressure Hook picks for single pin picking Rake picks for faster, less precise work Ball picks for wafer locks Half-diamond picks for versatility across lock types These basic tools are the foundation of lock picking and are essential for any locksmith offering lock repair services. Advanced Equipment for Modern Locks As lock technology advances, so do the tools needed to work with them: Electric pick guns that vibrate pins rapidly Tubular lock picks for circular keyways Decoder picks that can help determine the key cut Plug spinners to quickly reverse mistaken turning direction Locksmiths in Murray and surrounding Utah areas invest in these advanced tools to handle the full range of modern security systems. DIY vs. Professional Tools While hobbyist lock picking sets are available online, professional locksmith tools are: Made of higher-quality materials More precisely manufactured Designed for thousands of uses Custom-shaped for specific lock brands and models This difference in quality is why professional locksmiths can open locks more reliably and with less risk of damage than someone using a basic kit. Non-Destructive Entry Methods Beyond traditional picking, locksmiths have several other techniques to open locks without damage. Lock Bypassing Techniques Bypassing involves manipulating lock mechanisms without interacting with the pins or tumblers: Using a shim to retract the latch on some doors Manipulating the actuator directly on certain locks Exploiting design weaknesses specific to certain models Experienced locksmiths in West Jordan know which locks can be bypassed and which require more traditional approaches. Impression Methods Impression techniques involve creating a working key by: Inserting a blank key into the lock Applying pressure and slightly turning Removing the key to see where the pins have made marks Filing these marks carefully Repeating until a working key is created This technique requires patience but can produce a permanent key solution during a lockout situation. Decoding and Manipulation Some locks can be decoded by: Measuring internal components with specialized tools Using scope methods to visually inspect internal mechanisms Feeling and listening for specific feedback from the lock Locksmiths offering services in Sandy often use these non-invasive methods on high-security or expensive locks where preserving the lock's integrity is crucial. When Lock Picking Isn't Possible Sometimes non-destructive entry isn't possible, and locksmiths must consider other options. Drill Points and Minimal Damage Options When picking fails, professional locksmiths know: Precise drill points for different lock models How to drill just enough to manipulate the internal mechanism Techniques to minimize visible damage How to repair or replace only the damaged components A skilled Midvale locksmith can often drill a lock in a way that allows for repair rather than complete replacement. High-Security Lock Considerations High-security locks often include: Anti-pick pins with unusual shapes Sidebar mechanisms that resist traditional picking Hardened steel components resistant to drilling Restricted keyways that are difficult to access with tools These features may require specialized approaches or, in some cases, controlled destructive entry. When to Recommend Lock Replacement Ethical locksmiths recommend replacement when: The lock has been significantly damaged The security level is inadequate for the application The lock shows signs of wear that make it vulnerable The cost of repair exceeds replacement value Locksmiths in Murray often provide honest assessments about when repair makes sense versus when replacement is the better option. The Ethics and Legality of Lock Picking Professional lock picking comes with significant responsibilities. Locksmith Licensing Requirements In Utah, professional locksmiths must: Maintain proper business licensing Often undergo background checks Complete professional training or apprenticeships Follow industry ethical standards These requirements help ensure that those offering emergency lockout services are legitimate professionals. Legal Considerations When Picking Locks Legal lock picking is limited to: Locks you own Locks you have explicit permission to open Professional work with proper documentation Training and educational purposes in appropriate settings Reputable locksmiths in Sandy and surrounding areas always verify ownership and keep detailed records of their work. Lock Sport vs. Professional Practice There's a growing hobby community called "lock sport" focused on lock picking as a skill challenge. Unlike this hobby: Professional locksmiths pick locks to solve problems, not for entertainment They follow strict ethical guidelines about when and where to use their skills They prioritize security rather than defeating it Understanding this distinction helps clients appreciate the professionalism behind locksmith services. Finding a Reliable Locksmith When you're locked out, choosing the right locksmith matters. What to Look for in a Professional Locksmith A trustworthy locksmith will: Have verifiable local business information Provide clear pricing information upfront Arrive in a marked vehicle Carry professional identification Have positive customer reviews Offer multiple solutions to your problem These signs help distinguish legitimate locksmiths from those who might overcharge or use unnecessary destructive methods. Emergency Lockout Services Quality emergency services include: Fast response times to reduce your wait 24/7 availability for after-hours emergencies Mobile service that comes to your location Non-destructive entry as the first approach Fair pricing even for urgent situations When locked out in West Jordan, Murray, or nearby areas, these service standards matter. Preventative Lock Maintenance The best locksmiths don't just solve problems—they prevent them: Regular lubrication of lock mechanisms Adjustment of misaligned components Early identification of wearing parts Rekeying services when security concerns arise Recommendations for security upgrades when appropriate Investing in maintenance can prevent future lockouts and extend the life of your locks. Don't Get Caught Out in the Cold Next time you're facing a locked door without your key, remember that professional lock picking is a science—not magic or brute force. The right locksmith uses skill, knowledge, and specialized tools to get you back in without damaging your property. Need a trusted locksmith in Murray, West Jordan, Midvale, or Sandy?
