Should You Rekey or Replace Your Locks?
When it comes to protecting your home or business, deciding between rekeying your locks or a full lock replacementcan feel confusing. At Key World USA Locksmith, we help customers every day choose the best option based on their security needs, budget, and long-term goals.
What’s the Difference Between Rekeying and Replacing?
Rekeying Your Locks - Rekeying involves changing the internal pins and tumblers in your existing lock so that old keys no longer work. This is an excellent choice if:
You’ve lost a key and want to prevent unauthorized access
You’ve moved into a new home or rental property
You want to quickly and affordably reset access control
Replacing Your Locks - Lock replacement means removing the old hardware and installing brand-new locks. It’s the best option when:
Your locks are damaged, broken, or outdated
You want to upgrade to high-security or smart locks
Aesthetic changes are desired to match your doors or décor
Cost and Security Considerations
Rekeying is typically more affordable, since it only changes the internal components rather than replacing the entire lock.
Replacing your locks costs more upfront but provides the opportunity to upgrade your security system with advanced features such as bump-proof locks, smart locks, or keyless entry systems.
For many homeowners, rekeying is a practical solution. However, if safety is a concern or you want to modernize your property’s security, replacement might be the smarter choice.
