The Complete Guide to Rekeying Your Locks
Rekeying is a cost-effective way to secure your home without replacing all your locks. Learn when and why you should rekey — and when replacement is the better choice.
What Is Rekeying?
Rekeying is the process of changing the internal pins inside a lock cylinder so that the old key no longer works. A new key is then cut to match the updated pin configuration. The lock mechanism and hardware remain the same — only the key combination changes.
When Should You Rekey?
- Moving into a new home: You don't know who has copies of your keys — previous owners, contractors, real estate agents
- After a break-up or roommate change: Remove access for anyone who no longer lives with you
- After losing your keys: Prevent anyone who found them from entering
- After a break-in attempt: Even if they failed, your security may be compromised
- After firing domestic workers: Remove access for housekeepers, nannies, or contractors
Rekeying vs. Lock Replacement: Which Is Better?
Rekeying is the right choice when your locks are in good condition but you need new key access. Lock replacement makes more sense when:
- The lock is damaged or worn
- You want to upgrade to a higher security grade
- You want a smart lock or keyless entry
- All locks are different brands and you want master key compatibility
How Much Does Rekeying Cost?
Rekeying is significantly cheaper than full lock replacement. At Provo Locksmith UT, rekeying typically costs a fraction of what new hardware would. Call us at (385) 283-6134 for an accurate quote based on your specific lock types and how many you need rekeyed.
Can I Rekey My Own Locks?
Technically yes, with a rekeying kit, but it requires disassembling the lock and matching pin sizes precisely. Mistakes can make your lock non-functional. Professional rekeying takes 10-15 minutes per lock and costs very little — it's almost always worth hiring a pro.
