Lock Rekeying

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.

What homeowners should know

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.

When this service is needed

You moved into a new home or changed tenants and want to reset who has keys.
Keys were lost, stolen, or unaccounted for after contractors, sitters, or guests had access.
You want several doors to use one key for convenience (keyed alike).
You notice signs of tampering or bumped key marks around the keyhole.
A previous owner or occupant may still have copies and you want peace of mind.

Repair vs replacement

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.

Common problems to compare

Sticky or hard-to-turn key, grinding, or sluggish lock operation.
Misalignment between the lock and strike plate causing the bolt to bind.
Loose cylinder or wobbly hardware that will not stay tight.
Rusted or visibly worn locks that jam or risk breaking.
Fresh nicks or impact marks around the keyhole suggesting tampering.

Questions homeowners often ask

How much does rekeying usually cost?

Expect a service call fee plus a per-lock charge. Typical totals can land around the low hundreds for multiple locks, depending on the number of cylinders, lock type, brand/keyway, and timing. Ask for an itemized estimate before work begins.

Can a locksmith rekey if I do not have the original key?

Often yes, but it may take more time or special steps. In some cases, replacing the lock may be simpler or more economical. Ask what they recommend for your specific hardware.

Will rekeying make my home more secure?

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.

Can I make all my doors use one key?

Usually, if the locks are compatible (same or compatible keyways). Your locksmith can check brand and keyway and advise on any parts needed.

How long does rekeying take?

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.

What should I ask before booking?

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.

Is DIY rekeying a good idea?

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.
