Rekeying in Sherman Oaks

The cheapest way to change who can get in

Rekeying is one of the few genuinely efficient things in the locksmith trade. It takes a lock that works perfectly well and makes every existing key for it stop working, without replacing any visible hardware and usually in a few minutes per cylinder.

It is the right answer far more often than people assume. The instinct after moving into a house, or after losing a key, is to replace the locks — which is more expensive, takes longer, and on a property with four or five exterior cylinders adds up quickly for no additional benefit.

This page covers how it works, when it applies, and the situations where replacement genuinely is the better call. For home lock work more broadly, the residential page covers the wider picture.

In detail

What happens inside the cylinder

A standard pin-tumbler cylinder contains a row of small pin stacks. Each stack sits partly in the rotating plug and partly in the fixed housing above it. When the correct key is inserted, its cuts lift each stack to exactly the right height so the break between the two pins lines up with the edge of the plug, and the plug can turn.

Rekeying means removing the plug, taking out the existing bottom pins, and replacing them with a set cut to different heights — then cutting a key whose profile lifts them all to the shear line. Everything else stays: the lock body, the finish, the fixings, the installation.

The result is a lock that behaves identically and no longer recognises a single one of the keys that used to open it. It does not matter how many copies existed or who held them.

The same process allows several locks to be pinned to one key, which is why a rekey is the natural moment to bring a household's doors onto a single key. It also underpins master-key schemes, where extra pins in each stack create a second shear point so more than one key profile will operate the lock.

Common cases

When rekeying is the right call

You have just moved in

Nobody can account for how many keys exist on a house that has changed hands. This is the single most common reason to rekey.

A tenancy has ended

Keys returned prove nothing, because copies are cheap and leave no trace.

A key has gone missing

Particularly if it was on a fob with a tag, or lost near home.

Household access has changed

A relationship ending, a house-sitter finishing, a contractor handing back.

You want one key for several doors

Keyed-alike pinning, done during the same visit at very little extra cost.

A small business has had staff turnover

The same principle applies to commercial cylinders.

Reference

Rekey or replace?

The practical test: if the lock is mechanically sound and suited to the door, rekey it. Otherwise replace it, and bring the other doors onto the new key while you are there.

Common questions

Rekeying questions

A few minutes per cylinder once the technician is set up, so a typical house with four exterior doors is short work. Several units in the same building are quicker still per door, because the setup is already done.

No. Nothing about the lock body, the installation or the finish changes. The only difference is which key operates it — and a properly rekeyed cylinder should turn at least as smoothly as before, because it has been cleaned in the process.

Most standard pin-tumbler cylinders can. Some low-cost imported locks were never designed to be serviced, and certain proprietary systems require authorised dealers. A worn plug that no longer holds pins reliably should be replaced rather than re-pinned.

Yes, and that is often sensible. Keyed-alike sets are convenient but not always what you want — a garage or workshop that a gardener or contractor needs to reach is better kept separate from the residence.

Usually, subject to your lease, and most require management to hold a key for emergency access. Rekeying and providing them with a new key is normally acceptable; keeping the only key often is not. Raise it in writing first.

Tell us how many cylinders are involved and whether you want them on one key.

Photographs of the lock face, door edge or key help us identify the hardware before a visit.

We use these details to respond to your request. See our privacy policy. Access work requires proof of ownership or authorisation.

Identification is required

For any work that provides access to a property, vehicle or safe, the technician will ask for photo identification and evidence that you are entitled to enter. Having that ready keeps the visit short.
