Lock rekeying changes the internal pins of an existing lock so old keys stop working and only new keys will open it. It is a common way to restore key control after a move, lost keys, or turnover, without replacing the entire lock.
Rekeying keeps your existing lock hardware but updates which key operates it. Many homeowners rekey to make all door locks work with one key, remove access from old keys, or as part of a security refresh. A locksmith adjusts the cylinder pins to match a new key profile.
Total cost often includes a service call plus a per-lock charge. Pricing can vary by the lock brand and keyway, number of locks, whether you want them keyed alike or master-keyed, and timing (after-hours or emergency service may cost more). For typical homes, a service call plus multiple locks rekeyed can fall into a mid-range total.
Rekeying does not repair worn or failing hardware. If your locks are sticking, loose, rusted, misaligned, or builder-grade, discuss repair or replacement and potential upgrades like a quality deadbolt and reinforced strike plate.
Choose rekeying when the lock hardware is in good working order and you mainly want to change who can access the home. Rekeying can also consolidate multiple locks to one key if they share a compatible keyway.
Consider replacement when locks are worn, loose, sticking, rusted, misaligned, or visibly damaged. Upgrading to a quality deadbolt and reinforced strike plate can improve resistance to forced entry. If you do not have a working key or you have a specialty or high-security cylinder, rekeying may still be possible but can be more involved; in some cases, replacement may be the simpler or more cost-effective path. Ask the locksmith to inspect hardware condition and explain options.

Rekeying restores key control so old keys no longer work. For stronger physical security, ask about upgrading to a high-quality deadbolt and a reinforced strike plate with long screws.
Usually, if the locks are compatible (same or compatible keyways). Your locksmith can check brand and keyway and advise on any parts needed.
Many standard residential cylinders can be rekeyed within minutes each once the locksmith is on site. Total time depends on the number of locks and their condition.
Ask about license/insurance where required, all fees (service call, per lock, after-hours), what is included (number of keys), hardware condition, compatibility for keying alike, warranty, arrival window, and ID verification steps.
Some lock brands offer rekey kits, but mistakes can cause jams or reduce security. If you are unsure, hiring a professional can help avoid damage and ensure proper setup.
