Both rekeying and replacing stop old keys from working, but they solve different problems. Here's how to decide.
Rekeying changes the pins inside an existing lock so a new key works and all old keys stop working, while keeping the same lock body. It is fast and economical, making it ideal when the hardware is in good condition and you simply want to reset who has access. Rekeying does not upgrade the lock's strength.
Replacing installs entirely new hardware. Choose it when locks are worn, damaged, or outdated, or when you want stronger, higher-graded locks or a different style. Replacement costs more than rekeying but is the only path to a genuine security upgrade or to fix failing hardware.
If your locks work well and you just moved in or lost a key, rekeying is usually enough and cheaper. If the locks stick, feel loose, or you want better protection, replacement is worth it. A locksmith can inspect your doors and recommend the most cost-effective option.
