Most people think of key duplication as a quick trip to a hardware counter. In Granada Hills, where homes are spread out between Balboa Blvd, Devonshire St and the foothills, that errand can eat an afternoon, and it doesn't help much when the key you need copied is a restricted one, a worn original, or a key for hardware that is decades old. Crenshaw Lock Company is fully mobile, so we bring the cutting equipment to you and make the copies at your door.
We have been serving Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar has worked on plenty of the 1950s and 1960s ranch hardware common across the northern San Fernando Valley. Old keys wear down, and a copy made from a worn copy can get progressively worse until it sticks, spins or fails. Cutting a clean duplicate from a good reference, or in some cases creating a key to the lock itself, gives you a spare that actually works smoothly.
We handle standard house keys, office and commercial keys, mailbox keys, and restricted or patented keyways that ordinary kiosks cannot copy. Because we are on location, we can test every new key in the lock it is meant for before we leave, rather than handing you something that turns out not to fit once you get home.
How it works in Granada Hills
- 1
Tell us what you need copied
Call (323) 997-8867 and describe the key or keys: house, office, mailbox, gate, or a restricted key stamped with a do-not-duplicate marking. Knowing the type of lock and how many copies you want lets us bring the right blanks.
- 2
We come to you
We are 24/7 and fully mobile, so we travel to your home, workplace or gate anywhere in Granada Hills. There is no shop to visit, and you do not have to leave the property or hand your only key to anyone.
- 3
Verify authority and inspect the key
For restricted keys and commercial systems, we confirm you are entitled to have copies made. We then inspect your original for wear. If the key is badly worn, we may recommend cutting from the lock instead so the copy is not a degraded copy of a copy.
- 4
Cut the duplicates on location
We cut the new keys with mobile equipment, matching the correct blank and keyway, and deburr them so they slide in cleanly and do not scratch up the inside of your lock.
- 5
Test in the actual lock
Every copy is tried in the lock it was made for: the front door, deadbolt, side gate or mailbox. If a key binds or turns roughly, we adjust or recut it before we leave.

Advise on next steps
If a lock is sticking, worn out or has keys floating around from former occupants, we can talk through rekeying or servicing instead of only adding more copies to a system you cannot fully account for.

What affects the price
- The type of key: a basic house key is a different job from a high-security, restricted or patented keyway that needs special blanks and authorization.
- How many copies you want, since each additional key adds cutting and testing time.
- The condition of the original, because a worn key may need to be cut by code or from the lock itself rather than simply traced.
- Whether the job involves specialty hardware such as mortise cylinders, gate locks or older mid-century entry sets where blanks are harder to source.
- Whether the keys are for a single lock or a keyed-alike set across several exterior doors.
- The time of day and the location of the property, since we operate 24/7 and travel to you.
Why Granada Hills chooses us
- Fully mobile service: the machine comes to your driveway, so you never have to give up your only key or drive across the Valley to a counter.
- Experience since 1987 with older residential hardware, including original ranch-home locksets that are worn and need careful handling.
- Every key is tested in the actual lock before we leave, instead of being handed over untested.
- We can work with restricted keyways when you have proper authorization, which standard copy kiosks generally cannot do.
- Honest advice: if your key is too worn to copy well, or you would be better served by rekeying, we say so rather than just cutting more keys.
- Available 24/7, which matters if you discover you have no spare late in the evening or on a weekend.
Key Duplication across Granada Hills
Granada Hills is a quiet, residential corner of the northern San Fernando Valley, and the housing here shapes what we see. In Old Granada Hills along Chatsworth St, many 1950s and 1960s ranch homes still carry their original front-door locksets, and keys cut decades ago have worn smooth. New owners often ask us to copy those keys and then discover the lock itself is tired. We can duplicate what works and advise on rekeying so every exterior door runs off one key. Calls in ZIP 91344, which covers much of the community, often follow exactly that pattern.
In Balboa Highlands, the Joseph Eichler tract of mid-century modern homes, preserving the look of the entry hardware matters to owners. Duplicating keys for that hardware calls for a gentle touch and the right blanks, and we aim to keep period-appropriate sets in use instead of swapping them for something that clashes with the architecture. Knollwood, near Knollwood Country Club, and the gated and hillside properties near the northern edge bring their own needs, including keys for driveway and side gates.
Up toward O'Melveny Park and the foothills in ZIP 91394, Santa Ana winds, dust and summer heat can leave exterior locks and gate hardware sticky, and a stiff lock chews up fresh keys quickly. When we cut copies there, we test them in the lock and flag anything that needs servicing. Whether you are near Balboa Blvd, Rinaldi St, Zelzah Ave or off the 118 or 405, we come to you. Call (323) 997-8867 any time.
