If your key gets stolen, you need to act fast. Rekeying is cheaper and quicker, letting you keep the same lock hardware but change its internal pins so the old key no longer works. Replacing the entire lock costs more but is necessary if the lock is old or damaged. Weigh the security risk with your budget, and always hire a professional locksmith for either option.
