OVERVIEW

What is lock rekeying?

Lock rekeying changes the internal pins of a lock so a different key operates it.

A technician often removes the cylinder, swaps the pin stacks to a new key code, and reinstalls it. The old key stops working, and the new key opens the lock.

Lock Specialists has served Simi Valley since 1973. Technicians hold a California locksmith license and pass a Live Scan background check.

TYPES

Types of lock rekeying

Each rekeying type fits a different access goal.

Lock rekeying by Lock Specialists in Simi Valley

Cylinder rekeying

Cylinder rekeying changes the pins in a single lock so it takes a new key. It suits one door that needs new access control.

Keyed-alike configuration

Keyed-alike setups let several locks open with the same key. Technicians set each cylinder to the same code, which suits a home with several exterior doors.

New-occupancy rekeying

New-occupancy rekeying resets every lock in a home or unit when occupants change. It removes access from former occupants without changing the hardware.

COVERAGE

What systems and components does lock rekeying cover?

The service covers the mechanical lock cylinders that accept rekeying.

Deadbolt cylinders: single-cylinder and double-cylinder deadbolts.

Knob and lever cylinders: entry and passage locks with a keyed cylinder.

Mortise and rim cylinders: pin-tumbler cylinders in common residential doors.

Mailbox locks: small pin-tumbler cylinders where the design allows.

Cylinders with worn or damaged pins may need repair or replacement before rekeying.

BENEFITS

What are the benefits of lock rekeying?

Rekeying reuses the lock you have and changes who can open it.

Existing hardware

The lock, handle, and bolt stay in place.

Control of access

Old keys stop working, and you choose who holds new keys.

Fewer keys to manage

Keyed-alike setups let one key open several locks.

Tested result

The technician checks each new key before leaving.

REPAIR OR REPLACE

Repair vs. replacement: which is appropriate?

Rekeying suits a lock in working order, not a damaged one.

Rekeying makes sense when

  • The cylinder turns smoothly and the bolt operates normally.
  • The problem is access, not wear or damage.
  • The cylinder uses a pin-tumbler design that accepts a new key code.

Replacement makes sense when

  • The cylinder is worn, bent, or sticking.
  • The cylinder design does not allow a new key code.
  • The cylinder has a history of damage or forced entry.

COST

What affects the cost of lock rekeying?

Cost depends on the number of locks, the cylinder type, and the number of keys needed.

Each additional lock or key adds work. Lock Specialists gives an upfront quote before beginning any work.

TIMING

How long does lock rekeying take?

The length depends on how many locks need work and how many keys you need.

A single cylinder takes less time than a whole house. Cutting and testing each key adds to the visit. Your technician confirms the schedule when you book.

WHAT TO EXPECT

What should you expect during lock rekeying?

The visit covers each lock and every key in order.

The technician confirms which locks and keys are involved.

Each cylinder is removed, rekeyed, and reinstalled.

New keys are cut and tested in each lock.

You receive the new keys before the technician leaves.

Keep old keys out of use once the new set is in your hands. Old keys stop working when the rekey is finished.

FAQs

Frequently asked questions about lock rekeying

Yes. Rekeying changes the pins so a lost key no longer operates the lock. The technician then cuts new keys that match the updated pin set.

Only when access changes. Rekeying helps after a lost key, a move, a departed household member, or a change in who holds keys.

Anyone who finds the key can open the lock. That risk continues until the cylinder is rekeyed or replaced.

Usually, yes. Rekeying works on most pin-tumbler cylinders. A worn or damaged cylinder may need repair or replacement before a rekey holds reliably.

Keep spare keys in a known place and limit how many copies exist. Lubricate the cylinder once a year, and test every key after the change.
