When you lose a key, move into a new home, or have a security concern, your first instinct might be to replace the entire lock. But in most cases, rekeying is faster, cheaper, and just as secure.
What Is Rekeying?
Rekeying means changing the internal pins of your existing lock so that old keys no longer work and a new key is cut. The lock hardware stays exactly the same — only the key combination changes. It takes about 10 minutes per lock and typically costs $25–$50.
What Is Lock Replacement?
Replacement means removing the entire lock unit and installing a new one. This is necessary when the lock is physically damaged, outdated, or you want to upgrade to a higher-security model — like a Grade-1 deadbolt or a smart lock.
When to Rekey
- You just moved into a new home or apartment
- You lost a key or gave a spare to someone you no longer trust
- You want all your doors to use the same key
- Your lock is in good physical condition
When to Replace
- The lock is visibly damaged, worn or corroded
- You want to upgrade to a deadbolt or smart lock
- The lock brand is low-security and you want better protection
- Your door frame or strike plate is damaged
The Bottom Line
If the lock is in good shape, rekey it. If you want better security or the hardware is compromised, replace it. When in doubt, call us — we'll give you an honest assessment on the spot, no upselling.
