What's the difference between rekeying and changing locks?
Rekeying & Keys · Answered by Lightning Lock & Key, Truckee–Tahoe’s locksmith since 1996.
The short answer
Rekeying changes the pins inside your existing lock so a new key works and old keys die — a fraction of replacement cost. Changing locks swaps the hardware entirely.
The full picture
Rekey when the hardware is fine and key control is the issue (move, lost key, departure). Replace when locks are worn, damaged, or you want a genuine upgrade.
Every situation has its wrinkles — a two-minute call gets you a straight answer for yours, and phone estimates are always free: (530) 308-6643.
