Lock changes in Studio City

Changing the lock, or just the key?

“I need my locks changed” usually means one of two quite different jobs, and the distinction is worth several hundred dollars on a house with four exterior doors.

If the goal is simply that the old keys stop working — after a move, a tenancy, a lost key — and the existing locks are mechanically sound, then rekeying achieves exactly that without replacing anything visible. It is faster and considerably cheaper.

Replacement is the right call when the hardware itself is the problem: worn out, damaged, unsuited to the door, or simply the wrong function for what you now need. This page is about those cases, and about what to fit instead. For the other route, see rekeying.

In detail

When replacement is genuinely the better answer

Five situations make replacement the right call rather than a more expensive way of achieving the same thing.

The plug is worn. Once a cylinder's plug has worn to the point that it no longer holds pins reliably, re-pinning it produces a lock that will fail again. No amount of servicing recovers that.

The hardware never suited the door. A latch-only knob set on a main entrance was inadequate on the day it was fitted. Rekeying preserves an arrangement that should not exist.

The lock is damaged. After a forced entry, or where a body has been drilled or broken, replacement is the only route.

You want a different function. A keypad, a connected lock, or a high-security cylinder with controlled duplication is a different product, not a different key.

Parts are no longer available. On obsolete patterns, each repair is a temporary measure and the next failure has no fix at all.

There is also a security argument for older hardware. A cylinder from the nineteen-fifties was designed against nineteen-fifties expectations. Modern cylinders with hardened anti-drill inserts and better pick resistance are not expensive, and on a main entrance the difference is real.

Reference

Choosing what to fit

On almost every door, the strike reinforcement matters more than the grade of the lock in front of it.

Choosing what to fit
DoorUsually suitsAlso worth doing
Main entranceSingle-cylinder deadbolt, or keypad if you want code entryReinforced strike with screws reaching the framing stud
Back or side doorThe same grade as the front — not something lighterBring it onto the same key as the front
Garage side doorDeadbolt; often the weakest opening on a propertyCheck the frame is sound before fitting anything
Interior office or storeKeyed lever set, separate from the main keyKeep the holder list short and written down
Exterior gateExterior-rated hardware with adjustment for movementConsider a keypad if service staff need access

Common cases

Reasons people change locks here

After a purchase, where hardware is also tired

Replacing and rekeying at once, so the new locks share one key.

Following a break-in or attempted entry

Replacing damaged hardware, and reinforcing the strike at the same time.

A lock that has been repaired twice already

A third repair is usually money spent on postponement.

Upgrading to a keypad or connected lock

A different function rather than a different key.

A secondary door with only a latch

Adding a proper deadbolt where there has never been one.

Obsolete hardware with no parts available

Where the next failure would have no fix.

Before you call

What helps when you call

  • How many doors need changing
  • Whether the existing locks are worn, damaged, or simply the wrong key
  • What function you want on each door
  • Whether they should all share one key
  • Door thickness, backset and bore size if you can measure them
  • Whether any door currently binds or the bolt throws short
  • Whether the property is owned or rented
  • A photograph of the door edge and the existing hardware

Process

How the visit runs

Describe it

The property or vehicle, the hardware involved, and what changed before the problem started.

Complete and test

Everything is tested in place before the visit ends.

Common questions

Lock change questions

A rekey, in most cases. If the existing locks are mechanically sound and suit the doors, re-pinning makes every previous key useless for a fraction of the cost. Replace where hardware is worn, damaged, inadequate for the door, or where you want a different function.

Yes. The common pattern is a well-specified front door and a lighter back door, which makes the back the obvious way in — and it is less overlooked. Fitting the same grade and bringing both onto one key costs little extra.

Up to a point. Moving from a basic cylinder to one with anti-drill inserts and better pick resistance is worthwhile on a main entrance. Beyond that, the money is better spent on the strike and the frame, because most forced entries split the jamb rather than defeat the cylinder.

Often, yes — on many doors the deadbolt and the handle set are independent, so the deadbolt can be replaced while the handle stays. On mortise locks the case may be serviceable with only the cylinder replaced, which keeps the visible furniture entirely.

A typical house with three or four exterior doors is straightforward work, longer if any door needs correcting first. Doors that have dropped or strikes that need repositioning add time, and it is worth doing rather than fitting new hardware to an uncorrected opening.

Request a lock change in Studio City

Tell us how many doors and whether the issue is the hardware or just the 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.
