Why spare keys matter more on a Hidden Hills estate
Hidden Hills is a gated, guarded city of large-lot equestrian estates, and that changes how keys get used. One property can have a front door, a patio door, a garage side door, a guest house, a barn, a tack room and a mailbox, and each of those has its own lock. A household rarely needs just one copy of each. Family members, a housekeeper, a ranch hand, a trainer and a contractor may all need to get in at different times.
The pattern we see in the trade, and have seen since 1987, is simple. A property runs for years on one or two keys. The original gets worn, someone loses one, and suddenly there is a single key in circulation and no margin for error. Making a spare while everything still works is the easier and more economical route compared with solving a lockout later.
This page covers what we copy, how we do it, what changes the cost, and what is specific to duplicating keys in Hidden Hills. If your real problem is that every key has gone missing, or you are locked out right now, call us anyway. The right answer may be a different service, and we will say so.
What kinds of keys can we duplicate?
Most keys that people think of as ordinary can be copied accurately. Others need extra steps or proof of authorization, and a few should not be copied by a walk-in shop at all. Here is how it breaks down.
- House keys: front door, back door and garage entry keys, including the standard pin-tumbler keys used on most residential locks.
- Duplicate deadbolt keys: deadbolts often use a different key from the knob or handle set, so each lock on the door gets checked separately.
- Apartment key copies and guest-house keys: common on estates with a separate guest structure or staff quarters.
- Office key duplication and commercial key duplication: desk, file cabinet, suite door and building keys, including keys that belong to a larger keyed system.
- Mailbox key duplication: for private locking mailboxes. Postal service locks follow their own rules, covered in the FAQs below.
- Barn, tack-room and outbuilding keys, which are often on padlocks or older hardware that needs a close look before cutting.
- High security and restricted keys, which follow a different process described below.
How does key duplication work, step by step?
Good copying is mostly about starting with the right blank and checking the result, not just running a key through a machine. This is how we handle it.
- You call (213) 577-1366 and tell us which locks the keys belong to and roughly how many copies you need. We note the type of key, and we ask whether there is any restricted or high-security stamping on it.
- We look at the original. We check for wear, bends and cracks, because a damaged original can produce a copy that binds or fails.
- We choose the correct blank. Keyways differ by brand and lock series, and a blank that looks right but is slightly off will cut a key that sticks.
- We cut the copy to the original's pattern, then remove burrs and clean the cut edges so the key does not shed metal into your lock.
- We test the new key in the actual lock, not on a bench. A key that looks perfect but turns roughly gets recut or replaced.
- We label copies if you have several locks, so you are not guessing later which key belongs to the barn and which to the guest house.

Call (213) 577-1366Why a copy of a copy causes trouble
Every duplication step can introduce a small error, and those errors add up. A key cut from a key that was itself cut from a worn key may be a fraction off in several places. The result is a key that works on a good day and jams on a hot one, or one that turns only when you jiggle it.
If your best key is already worn, tell us. Where possible we cut from the least-worn original you have. If every key you own is worn, it may make more sense to cut a fresh key based on the lock itself rather than copy a tired one, and we can talk through that option.
Sun and heat also matter on exterior hardware here. Hidden Hills has hot, dry summers and occasional Santa Ana winds, and sun exposure and heat cycling are the main stresses on exterior gate and door hardware. A lock that is slightly stiff in summer can make a marginal copy feel worse than it is, so we test and, if needed, point out when the lock itself needs attention.
What about restricted and high-security keys?
Some keys are deliberately hard to copy. High-security and restricted key systems use special keyways, controlled blanks and sometimes a registered owner or authorization card. That protects you, because it stops anyone who borrows your key for an afternoon from making their own.
If your key is part of one of those systems, expect us to ask for proof of authorization before we copy it. It is not a hurdle for its own sake. Anyone who could simply walk in and copy a restricted key would defeat the system you paid for. Depending on the system, the blanks may only be obtainable through the manufacturer, which can add time. In some cases the key can only be ordered by the registered owner.
Stamped warnings on a key are another gray area. A key marked as not for duplication is a request, not a legal barrier, but we treat it as a reason to ask questions. If you are installing new locks and want copying to be controlled from the start, our page on high-security locks explains how those systems work.
Can we come to you? Mobile key duplication in Hidden Hills
Hidden Hills is about 24 miles from our Westwood storefront at 10740 Wilshire Blvd, and most estate owners would rather not drive that far for a few keys. That is what our mobile locksmith vans are for. We bring the work to your property.
Depending on the key, we can often cut copies on site. Some keys, especially unusual keyways, restricted blanks or older padlock keys, may need blanks we have to bring from the storefront or order. We tell you which situation you are in when you call, so you are not left waiting for a visit that cannot finish the job.
Because Hidden Hills is guarded, we will need to be cleared through the staffed gates. Tell us the address and who will authorize our entry, and we will plan around that. If you are at the property when we arrive, we can test every copy in its lock before leaving.

Call (213) 577-1366What affects the cost of key duplication in Hidden Hills?
We do not quote numbers on a web page because the price depends on what is in your hand. These are the real factors.
The type of key matters most. A common house key is a simple job. A high-security or restricted key needs special blanks and sometimes authorization, which adds cost and handling. Keys with electronic chips, such as many car keys, involve programming on top of cutting.
Quantity matters too. Several copies from one setup are more efficient than separate trips. Cutting from a good original is also more efficient than building a key from a worn one.
Location and timing play a part. A mobile visit to an estate involves travel, and an after-hours call involves different staffing than a daytime visit. If you can plan ahead and group several keys into one visit, that is usually the more economical route.
Finally, the condition of the lock affects the outcome. If a fresh copy will not turn smoothly because the lock itself is worn, repairing or replacing the lock may be needed in addition to cutting a key. We will explain that before doing extra work, so you decide what to spend.
Key duplication around Hidden Hills: gates, barns and rebuilds
Hidden Hills is a single ZIP code, 91302, but the city covers a lot of ground, and the way keys get used varies from one part of it to another. Along the Long Valley Road corridor near the main gate, many homes are large custom builds that may have a lot of exterior doors, each keyed differently. Around Round Meadow Road and Jed Smith Road, you find a mix of original 1950s and 60s ranch houses and much larger rebuilt homes, and the locks on those two types are often very different ages.
Properties on the western edge, close to the Upper Las Virgenes Canyon Open Space, and those on the southern edge near The Commons at Calabasas, are reached through the same staffed gates, but their outbuildings and side doors can be a long way from the house.
The scenario we see tied to duplication most often is barn, tack-room and outbuilding locks on bridle-trail lots. Those locks tend to be older, exposed to dust and heat, and keyed separately from the main house. The keys also pass through more hands: stable help, trainers, farriers and contractors. A well-labeled set of copies for those buildings prevents the common scenario where one worn key is the only way into the tack room.
Remodels and rebuilds of original ranch homes are the other big one. When a house is renovated, keys multiply: the builder, the project manager and subcontractors all want access. We can cut working copies for a project team. When the work is done, a rekey is usually a better way to reset who holds a key than chasing down every copy.
Driveway gate hardware is a different animal. Estate gates, keypads and intercoms are separate from key copying, and if a gate lock or operator is the actual problem, see our gate lock repair page. We can still copy the manual keys that go with those gates.

Call (213) 577-1366When a copy is not the right answer
Duplication solves one problem, which is not having enough keys. It does not solve every key problem, and we will tell you when something else is the better move.
If you do not know who has copies of your keys, perhaps after a remodel, a staff change or a rental, then rekeying your locks makes the old keys useless and gives you a clean start. If you manage many doors and want different people to have different access, a master key system is built for that.
If you are tired of managing physical keys for family, staff and vendors, a smart lock can issue and cancel access without cutting anything. Many people still keep a mechanical backup key, which we can cut as well.

Frequently asked questions
Can you copy keys at my Hidden Hills home instead of me bringing them in?
Yes, in most cases. Our mobile vans come to the property, and for many common keys we can cut and test the copies on site. For unusual keyways or restricted blanks we may need to bring parts from the storefront, and we will tell you that when you call (213) 577-1366.
Will you copy a key stamped Do Not Duplicate?
We treat that stamp as a sign to ask questions. For ordinary stamped keys we confirm you have the right to copy it. For restricted high-security systems we require proper authorization before cutting, because that control is what the system is for.
Can you duplicate a car key?
We can discuss it, but modern car keys often contain a chip that has to be programmed in addition to being cut. What is possible depends on the vehicle, so we confirm by VIN or in person, and some vehicles may only be handled through a dealer. See our page on transponder key programming for more.
Can you copy my mailbox key?
For a private locking mailbox, yes, in most cases. Postal-service-controlled locks follow postal rules, so if your box is one of those, the postal service handles replacement. If you need the lock itself changed instead, our mailbox lock replacement service is the one to read about.
What if I have lost my only key?
Then there is nothing to copy from. We would look at the lock and decide whether we can make a new key from it, or whether replacing or rekeying the lock is more sensible. Call us and describe the lock, and we will explain the options.
Why does my new copy stick when the original works fine?
Usually the wrong blank was used, the cut was slightly off, or the original was worn and the copy inherited the error. Bring it back and we will test it in the lock and recut or replace it as needed.
Do I need to be home for you to copy keys?
It helps, because we can test each copy in its lock before leaving. If you cannot be present, you can arrange for a trusted person to meet us, and we will need entry cleared through the Hidden Hills gates either way.
How do I know a locksmith is legitimate?
Ask for their BSIS LCO license number, which California requires of locksmith companies. Also ask whether they have a physical location and whether the person arriving works for the company you called. Any honest locksmith will answer those plainly.
