When Key Duplication is Useful
Key duplication is ideal for:
- Providing spare keys for family members or roommates.
- Giving temporary access to maintenance workers or cleaners.
- Replacing a worn-out or broken key without changing the lock.
For example, if you’ve recently moved into a new home in Las Vegas and want to give a spare key to a neighbor or friend, a simple key duplication is quick, convenient, and cost-effective.
Limitations of Key Duplication
While key duplication is straightforward and inexpensive, it comes with some limitations:
- It does not improve security. Anyone with access to the original key can create a copy.
- Lost or stolen keys can still be used to access your property.
- High-security locks often require special keys that cannot be duplicated at home or by unauthorized vendors.

What is Rekeying?
Rekeying, on the other hand, involves changing the internal mechanism of a lock so that the old key no longer works. In other words, rekeying makes your existing locks operable with a new key.
When Rekeying is Necessary
Rekeying is the safer option in situations such as:
- You’ve lost a key or had one stolen.
- You’ve recently moved into a new home or office.
- You’re concerned that former tenants or employees might still have access.
- You want to consolidate multiple locks under a single key for convenience.
For example, if you’ve recently moved to Henderson, NV, and aren’t sure who might still have copies of the keys to your home, rekeying your locks ensures that only you have access.
Benefits of Rekeying
- Improved security: Old keys no longer work, reducing the risk of unauthorized access.
- Cost-effective: Rekeying is often cheaper than replacing locks entirely.
- Convenience: You can rekey multiple locks to work with the same key.
Key Differences Between Duplication and Rekeying
Understanding the differences between key duplication and rekeying helps you make an informed decision:
| Feature | Key Duplication | Rekeying |
|---|---|---|
| Purpose | Makes an exact copy of your existing key | Changes the lock to work with a new key |
| Security | No improvement | Improves security |
| Cost | Low | Moderate, depending on the number of locks |
| Time | Very quick | Usually takes longer, may require professional tools |
| Best Use | Spares, temporary access | Lost keys, new homeowners, security upgrades |
How to Decide Which Option You Need
When deciding between key duplication and rekeying, consider the following questions:
- Do you want to improve security?
If yes, rekeying is the way to go. Duplication won’t prevent unauthorized access. - Do you need more keys for family, friends, or employees?
Key duplication is faster and cheaper for creating multiple copies of the same key. - Have you recently moved or lost a key?
Rekeying ensures that previous keyholders cannot enter your property. - Are you on a budget?
Duplication is generally less expensive, but consider the long-term security benefits of rekeying.
Why Hire Professional Locksmiths
While some people may attempt DIY key duplication or rekeying, there are significant benefits to hiring professional locksmiths:
- Expertise: Professional Locksmiths have the training to handle all types of locks efficiently.
- Proper Tools: Rekeying requires specialized tools to adjust the lock pins and ensure smooth operation.
- Safety: Incorrect duplication or rekeying can damage the lock, leaving your property vulnerable.
- Convenience: A professional locksmith can complete the job quickly, sometimes on the same day.
Rekeying vs. Replacing: Which Is Better?
Some people wonder whether rekeying is enough or if they should just replace the lock entirely. While replacing a lock can provide brand-new security, it is usually more expensive than rekeying. If your existing locks are in good condition, rekeying offers a cost-effective way to ensure security without buying new hardware.
However, if your locks are old, rusty, or worn out, replacement may be a safer long-term investment. A professional locksmith can evaluate your locks and recommend the best solution.
Conclusion
Both key duplication and rekeying have their place in maintaining home or office security. Key duplication is great for adding spare keys, while rekeying is essential for improving security and preventing unauthorized access. By understanding the differences, you can make the best choice for your specific situation.
