Can I rekey a lock without the original key?

Rekeying locks when the original key is missing in Alexandria, VA

A lock may be rekeyable without its original key, but feasibility depends on the cylinder, current access and condition. A locksmith should assess those factors before you assume either rekeying or full replacement is necessary.

Which situation are you in?

An open door with a missing key and a locked entrance with no working key are different requests. Find the one closest to yours to see what it means and what to have ready.

You can get in

The door is open, but the original key is gone

What it means
The lock can be looked at where it is, without anyone needing to get you inside first.
Have ready
Any keys you still have for the lock, and the brand name if one is printed on it.
Ask about
Whether this cylinder can be rekeyed as it is, or whether it has to be replaced.
Locked out

The door is locked and no key works

What it means
This is two jobs: getting through the door, then deciding what to do with the lock.
Have ready
Identification, plus a document that links you to the address. Ask which ones are accepted.
Ask about
Getting in first, then whether rekeying or replacement suits the lock afterward.
What to do during a lockout
Some keys work

You have working copies, but not the original

What it means
A working key can matter, because some rekeying procedures need one. Copies of unknown origin are still a reason to rekey.
Have ready
Every key you were given, and a count of the locks they open.
Ask about
Rekeying the locks so the copies you were handed stop working, and how many new keys you get.
How rekeying works

Why the original key can matter

A pin-tumbler lock turns when the cuts on the key lift every stack of pins to the same line. Rekeying replaces pins inside the cylinder so that a new key lines them up and the old key no longer does.

Some product procedures require a current working key. Manufacturer-specific instructions should not be applied to a different cylinder or to a lock with missing prerequisites. Ask a qualified provider about your particular hardware.

This page explains the idea only. How a particular cylinder is opened and repinned depends on the hardware and is work for a technician.

BeforeOriginal key: every pin stack splits at the turning line.
After rekeyingOld key: the red marks show pins that now block the turn.
Weighing it up

Rekey or replace when the key is missing?

The missing key on its own rarely decides it. The lock's condition and what it is compatible with usually do.

Rekeying may suit when

  • the lock works smoothly and is in good condition
  • the cylinder is one that can be rekeyed
  • you want every old copy to stop working
  • you would like several locks on one new key

Replacement may suit when

  • the lock is damaged, loose or badly worn
  • the cylinder does not take a new key
  • you want a different kind of lock anyway
  • parts for that hardware are not available

For the broader choice, see our comparison of rekeying versus replacing locks, or the lock replacement page if a new lock is likely.

Before the visit

What a technician will want to know

Explain the access situation and identify the lock brand where visible. The provider also needs to establish your authority to request work.

  • the brand name on the face of the lock, if there is one
  • the type: deadbolt, knob, lever, or a smart lock with a key slot
  • how many locks you want on the new key
  • whether any key at all still works
  • a clear photo of the lock face, if you can take one

Owners and tenants can ask which proof of authority is accepted before the visit, so nothing holds the work up at the door.

When it comes up

Common reasons the original key is missing

The answer to whether a lock can be rekeyed is the same in each case: it depends on the lock. What changes is who needs to approve the work.

You just bought the home

Previous owners, their family and contractors may all have had copies. Nobody can say how many are still out there.

A tenant moved out

Keys come back incomplete, or not at all. The owner or manager is usually the one who can approve a lock change.

Keys were lost or stolen

A missing ring, especially with an address tag on it, is a common reason to change which key the locks accept.

A smart lock's backup key is gone

Many smart locks keep a key slot for backup. Our smart lock installation page covers those locks.

Older locks with no keys at all

Rowhouses in Old Town and older homes in Rosemont can come with hardware nobody has a key for. Mention the age of the door when you call.

A business moved into a space

Earlier tenants and their staff may still hold keys. Our commercial locksmith page covers business doors.

Shut out of the property as well?

Getting in comes first. See what to do during a lockout for what to have ready, or our lockout service page.

Lockout steps
Before you agree to the work

Three questions to settle first

Ask whether the existing hardware can remain, what new keys are included and what additional work might be required.

  1. Can my hardware stay?

    Keeping the existing lock is often the point of rekeying. Ask whether that is possible here, and why if it is not.

  2. How many keys come with it?

    Count the people who need a key before you call, so you know whether extra copies are needed.

  3. What else might be needed?

    A worn part or a lock that has to come off the door can add to the job. Ask so it is not a surprise.

Questions

Frequently asked questions

Can a lock be rekeyed if I lost the original key?

It may be. That depends on the cylinder, its condition and whether you can still get in. The lock needs to be assessed before you assume either rekeying or replacement.

Can I rekey my own lock without the key?

Some rekeying procedures need a current working key, and instructions written for one product should not be used on another. Ask a qualified provider about your hardware.

Is rekeying or replacing better when the key is missing?

It depends on the lock. Rekeying keeps sound hardware in place when the cylinder allows it. A damaged lock, or one that cannot take a new key, may need replacing.

Will I need to show that I own or rent the property?

Expect to be asked to establish your authority to request the work. Ask which ID and proof are accepted before the visit.

Can the new key work on several of my locks?

Often, when the locks are compatible with each other. Mention the brands and the number of locks when you call.

What happens to the old keys after rekeying?

They stop operating the rekeyed locks. Copies held by previous owners, tenants or anyone else stop working on those locks too.
