When you move into a new place or lose track of who has keys, commercial rekeying services offer a practical fix. Instead of replacing every lock, a technician adjusts the internal pins so your existing keys no longer work, while a new master key fits all rekeyed locks. It's quicker and cheaper than full lock swaps, giving landlords and business owners fast control over access without changing hardware.
