Rekeying Vs. Replacing A Lock: Everything you need to know

August 30, 2023

Since our safety and that of our loved ones is our top priority, giving quality attention to the locks on our doors is very important. So whether you’ve lived in your current apartment for many years or you’ve just moved into a new home, replacing your locks is always a great idea. But what about rekeying them? What’s the difference anyway?

What does replacing a lock mean?

Replacing a lock is simply changing an existing lock with a new one by using a new lockset on the same door. It may be due to reasons such as: Having old, faulty locks; losing your keys; moving into a new home, etc.

This is the most popular choice among homeowners, business owners, etc. In fact, many people don’t know that there are other options available regarding lock problems.

What does rekeying a lock mean?

Rekeying of locks, on the other hand, is quite different. Firstly, locks contain ‘tumblers’ or ‘key pins’ inside them that correspond with a certain key.

When rekeying a lock, a locksmith opens up the existing lock and replaces the key pins inside with new ones, such that the current key can no longer work on that lock.

The lock stays in place but a new set of keys will be used to open it.

Most people are not aware of this option, hence, the reason why the lock replacement option is often patronized.

When is the best time to replace a lock?

The best time to replace a lock is when:

  • You want to upgrade the entire security system of your locks. With the rise in the rate of burglary incidences, this could be seen as a wise decision to make e.g upgrading your locks to a key card or other digital options.
  • The existing locks are old, malfunctioning, or worn out. Getting a malfunctioning lock rekeyed makes no sense. It’s best to have them replaced with new ones that work well.
  • They were tampered with during a burglary incident or an attempted one.
  • You want to give your locks an aesthetically pleasing look that complements your property. As simple as it sounds, changing your locks could give your doors the facelift that you desire!

When is the best time to rekey a lock?

The best time to rekey a lock is when:

  • You lost your keys or they were stolen. In order to get a new set of keys for your locks without changing them entirely, you’ll have to rekey them.
  • You moved into a new home. When you move into a new home, you are unsure of other people that might have copies of your keys. It is safer to rekey your locks in order to avoid unwanted visitors.’
  • You prefer to keep a master key. Some people prefer to use a single key for more than one lock. The locksmith can rekey the different locks to correspond with a single key. This is possible if the locks are of the same brand. 

What are the benefits of lock replacement vs. rekeying?

In order to arrive at a decision on whether or not to replace or rekey your locks, you have to know the benefit of each option.

Benefits of lock replacement

You feel safer

Lock replacement is best recommended when the existing locks are malfunctioning or worn out. In this situation, rekeying your lock might not do the job of ensuring your safety.

There’s also that confidence that comes with having newly installed locks. You’re almost sure about your safety because they are brand new.

Customization

You get to change your locks to look a certain way that appeals to your taste and matches your style. 

Benefits of lock rekeying

Affordable and easy

Rekeying your lock is a much easier and more affordable way to secure your home. Your existing lock set is used and you only end up losing a key, which makes it cheaper.

But this solution depends on the situation involved. It will be unnecessary to replace a malfunctioning lock. Rekeying should be done in the case of lost or stolen keys etc.

Also, in the process of rekeying a lock, the locksmith can inspect the lock’s condition, confirm if it was properly installed, and correct an issue if any is found. This serves as a form of maintenance which is only a benefit of lock rekeying. 

What is your budget for lock replacement and rekeying?

Lock replacement usually results in a much higher cost compared to lock rekeying. This is because it requires getting a new lockset or hardware, depending on the nature of the lock.

So, if you only lost your keys or they got stolen, why spend more when you can have your locks rekeyed? 

Should you replace or rekey your locks by yourself?

Yes — if you’re a professional locksmith.

Locks serve as our first line of defense against burglars. They should be treated with additional care and attention. As a home or business owner, you would care a lot about the safety of your family or customers.

It is best to allow your lock replacements or rekeying to be done by professionals in order to ensure an excellent job. You might be saving yourself some money by doing it yourself but a poorly done job could easily jeopardize your safety and put you at risk of burglary attacks or unwanted visitors.

  • A professional locksmith is highly skilled. They are trained to work with all kinds of locking mechanisms.

It happens to the best of us. You're running late, juggling groceries or half-awake on your way to work, and before you realize it—the door clicks shut, and your keys are inside. Getting locked out isn’t just inconvenient—it’s stressful, time-consuming, and sometimes downright expensive. The good news? It’s also highly preventable. In this comprehensive guide, we’ll walk you through smart, real-world strategies to avoid getting locked out again—whether it’s your home, office, or car. These expert prevention tips come straight from the locksmith trenches, and they’re easy to apply, whether you’re forgetful, busy, or just tired of relying on emergency locksmiths. Understand Why Lockouts Happen in the First Place Before solving the problem, we need to understand it. Lockouts typically happen due to: Forgetting or misplacing keys Keys getting locked inside a car or home Doors that auto-lock Broken or worn-out keys Malfunctioning locks or key fobs Most of these are preventable with simple habits, upgrades, or tools. Let’s break them down one by one. Step 1: Create a Key Routine That You Can Stick To One of the most powerful prevention tools? Muscle memory. Create a ritual around your keys—something small and repeatable every time you leave your home, office, or car. For example: Always touch your keys before shutting the door Say “Phone, Wallet, Keys” as a mental checklist Place a reminder near the door (“Do you have your keys?” sign) These tiny behaviors train your brain to check for keys automatically—no effort required after a while. Step 2: Store a Spare Key (But Not Under the Mat!) A spare key is your best backup—but only if it’s stored smartly. Avoid outdated hiding spots like under the doormat, flowerpot, or inside the mailbox. These are the first places burglars check. Instead: Leave a spare with a trusted neighbor or friend Install a secure, weatherproof key lock box with a code Store it in your wallet or bag if it doesn’t interfere with routine And whatever you do, never label your key with your name or address. If it’s lost, your home could be at risk. More on this in our guide: Why You Should Never Hide a Spare Key Under the Mat Step 3: Duplicate and Distribute—Strategically Don’t rely on one key to rule your world. Instead, get professional duplicates made and keep them where you’re most likely to need them. Some smart storage ideas include: One in your car (but hidden securely) One in your gym bag or laptop case One at your workplace One with your dog walker, babysitter, or close family member Just make sure you trust whoever has access—and always update your key plan after roommates or tenants move out. Step 4: Go Keyless With Smart Locks If lockouts are a recurring issue, it might be time to ditch the keys altogether. Smart locks allow you to unlock doors using: Keypads (PIN codes) Smartphones Fingerprint access Bluetooth or Wi-Fi apps Some models even let you generate temporary codes for guests or service workers—so you don’t have to hide a key or hand out spares. Check out How to Upgrade to a Smart Lock Without Changing Your Door for a step-by-step breakdown of modern options that don’t require full door replacements. Step 5: Regularly Inspect Your Locks and Keys Sometimes, it’s not forgetfulness—it’s a failing lock or worn-out key that locks you out. Signs your key or lock may be due for a replacement: Your key feels loose or stiff in the lock You have to jiggle it to get it to work Your key is cracked, bent, or visibly worn You hear clicking, scraping, or feel resistance when turning A quick inspection once a month can catch small issues before they leave you stranded on the porch.

Step 6: Have a Go-To Locksmith on Speed Dial In case prevention fails (because life happens), don’t waste time Googling at 2AM when you're locked out. Instead: Research a local, licensed locksmith now Save their number in your phone as “Emergency Locksmith” Confirm they offer 24/7 lockout assistance Check their reviews, verify their licensing, and build a relationship with them before you need them. Our guide on How to Find a Licensed and Trustworthy Locksmith Near You walks you through exactly how. Step 7: Use a Smart Reminder or Tracker If you’re forgetful (hey, we’ve all been there), tech can help: Use a Tile or Apple AirTag on your keychain to track misplaced keys Set location-based reminders on your phone to check for keys before leaving Use apps like “Alarmy” to set a custom checklist for leaving the house These small hacks go a long way in building dependable habits. Bonus Tip: Re-Key After a Lockout (If Needed) If your lockout was caused by lost keys, it’s safer to rekey or replace the locks afterward. Why? Because if someone finds your keys and knows where you live, your home is no longer secure. Not sure what’s best? We break it down in Rekey vs Replace Locks: Which Is Better for New Homeowners? Final Thoughts: Lockouts Are Avoidable With the Right Systems A lockout doesn’t have to be part of your weekly routine. With a few simple changes—like key duplication, smart storage, tech upgrades, and routine maintenance—you can make sure that panic moment at the front door never happens again. It’s not about being perfect. It’s about being prepared. If you ever do get locked out again, don’t panic. Just call your trusted locksmith and take it as a reminder to refine your prevention system. You’ve got this—and your keys.
