Most people think of key duplication as a quick stop at a hardware counter. In Porter Ranch, that errand often means a drive down Reseda Blvd or Rinaldi St, and it gets harder when the key is stamped 'Do Not Duplicate', belongs to a gate system, or is the only one you have. Crenshaw Lock Company is fully mobile, so we bring the cutting equipment to you. There is no storefront to visit, and we are available 24/7.
Copying a key properly is more than tracing a shape. Worn originals can pass their wear on to the copy, and a copy of a copy drifts further from the factory cut each time. When we duplicate a key, we check how the original operates in your lock first. If the key is tired, we may suggest cutting a fresh key by code or from the lock itself rather than copying the worn one.
David Shar has run Crenshaw Lock Company since 1987, serving Greater Los Angeles and Ventura County. That history covers a lot of the hardware found in newer master-planned communities like Porter Ranch: builder-grade deadbolts, smart locks paired with traditional keyways, mailbox locks, and HOA amenity keys. Whether you need one spare for a house sitter or a full set for a family, we can handle it at your door.
How it works in Porter Ranch
- 1
Tell us what needs copying
Call (323) 997-8867 and describe the keys: house, mailbox, office, gate, or a restricted keyway. Mention how many copies you need and whether any original is worn or marked as restricted. That helps us bring the right key blanks.
- 2
We come to your location
Our mobile service comes to your home, office or HOA building in Porter Ranch. Because we work from the vehicle, there is nothing for you to drop off and no need to leave your property.
- 3
Inspect the original key and lock
Before cutting, we look at the original key for wear and burrs and test it in the lock. In a hillside home where dust and grit have built up in the cylinder, a sticky lock can make a good key seem bad, so we sort out which one is the problem.
- 4
Verify authorization for restricted keys
Restricted and 'Do Not Duplicate' keys are controlled for a reason. We ask for appropriate proof of authority, such as an HOA or management authorization, before copying them. Standard residential keys do not require this step.
- 5
Cut, test and adjust
We cut the new keys, remove burrs, and test each one in the lock several times. A copy should turn smoothly without forcing. If it does not, we adjust or recut it on the spot.
- 6
Hand over and advise
We give you the keys and explain which is the master original and which are copies. If a lock is worn, we will tell you honestly whether rekeying or replacement makes more sense than more copies.

What affects the price
- The type of key: a standard house key, a high-security or restricted key, a mailbox key and a gate or amenity key all involve different blanks and cutting methods.
- How many copies you need, since a single spare and a full set for a household are different jobs.
- The condition of the original key, because a worn original may need to be re-cut by code or from the lock rather than simply copied.
- Whether the keyway is restricted and requires authorization or special blanks.
- The time of day you call, since we are available 24/7 and after-hours service can differ from daytime appointments.
- Whether the visit also includes related work such as cleaning a fouled cylinder or rekeying, which is quoted separately from the copies.

Key Duplication across Porter Ranch
Porter Ranch sits on the northwest rim of the San Fernando Valley, below the Santa Susana Mountains, and its housing reflects that. Many homes in The Oaks of Porter Ranch, Porter Ranch Estates and the Renaissance and Sorrento tracts were built from the 1980s onward, and a lot of them sit behind gates. Households often juggle a front door key, a garage entry key, a mailbox key and a gate or intercom credential. We can duplicate the physical keys and help you sort out which ones you actually need.
Hillside properties near Aliso Canyon Park and Limekiln Canyon Park deal with wind-driven dust and Santa Ana grit. That grit works its way into exterior cylinders and makes keys stick, which is why a copy that seems to fail is sometimes a dirty lock. For homes in ZIP code 91326 and 91327, we check the cylinder before cutting, and clean, lubricate or replace a seized cylinder when needed.
Near The Vineyards at Porter Ranch Town Center and Porter Valley Country Club, we also see HOA and association needs, such as clubhouse, pool and amenity-building keys after a management change. Those are often restricted, so we work with the proper authorization. We reach residents and managers off Tampa Ave, Corbin Ave, Mason Ave, Sesnon Blvd and Porter Ranch Dr, and drivers coming off the Ronald Reagan Fwy (SR-118). Call (323) 997-8867 any time.
