Rolling Hills is unusual: a single fully gated enclave of large ranch-style estates on lots of an acre or more, set along quiet, unlit private roads. The manned gates help a great deal, but they are not a lock on your front door, your barn, or your tack room. Many homes here are mid-century ranch houses from the 1950s and 60s, and plenty still carry the locksets they were built with. A high security upgrade is often the most sensible way to close the gap between a well-protected community and a vulnerable individual property.
High security locks differ from standard hardware in how they are built. They use tighter tolerances, hardened components and more complex pin or key designs to resist picking, bumping and drilling. Many also use restricted keyways, meaning keys cannot be casually duplicated at a hardware counter. For a property with a main house, a guest house, a barn and perhaps several people who come and go, key control may matter as much as the lock itself.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, with no storefront, so every consultation and installation happens on your property. We look at your doors, your frames and how your household or ranch actually operates, then recommend hardware that fits rather than the most expensive option on the shelf.
How it works in Rolling Hills
- 1
Talk through the property
Call (323) 997-8867 and tell us what you want to protect: the main residence, a guest house, barn doors, a tack room, or all of them. We ask about who has keys now and any recent changes in staff or caretakers.
- 2
Gate clearance and arrival
Rolling Hills entry is controlled by manned security gates. We coordinate with you so we can be cleared at the gate and find your address along the private roads, which saves confusion for everyone.
- 3
Assess doors, frames and existing hardware
On site we inspect the door, the strike plate, the frame and the current lock. A strong cylinder is of limited use in a weak frame, so we note anything that needs reinforcing. On older ranch homes we also check for corrosion and wear.
- 4
Recommend a lock and key-control level
We explain the options in plain terms, including pick-, bump- and drill-resistant cylinders and restricted keyways, and help you choose how tightly keys should be controlled across the house and outbuildings.
- 5
Install and fit-test
We install the new hardware, adjust it so the bolt throws cleanly and test every key. If you want several locks on one keying system, we set that up so one key can operate the doors you choose.
- 6
Hand over keys and explain use
We give you the keys, explain any restrictions on duplication and how to order additional copies, and suggest simple habits for tracking who holds what.

What affects the price
- The grade and brand of the lock: higher-security cylinders with restricted keyways and hardened components cost more than basic upgrades.
- How many doors you are securing, including the main house, guest house, barn and tack room, and whether they share one keying system.
- The condition of the doors and frames, since reinforcement or strike plate upgrades may be needed on older mid-century construction.
- Whether existing hardware is corroded or damaged by the hilltop fog and salt air and needs full replacement rather than a cylinder swap.
- The number of keys and the level of duplication control you want, including extra restricted keys for family or staff.
- Whether the work is scheduled in advance or requested after hours, since we are available 24/7.
Why Rolling Hills chooses us
- Fully mobile service: we bring the work to your estate, with no shop to drive to.
- Serving Los Angeles and Ventura Counties since 1987, so we have seen older ranch-era hardware many times.
- We think about key control for properties with staff, caretakers and outbuildings, not only the front door.
- We recommend what fits your doors and frames, and we tell you when a frame fix matters more than a fancier lock.
- Available 24/7, so a security concern does not have to wait for business hours.
- The owner, David Shar, leads the work, so the person who guides your decision understands the trade.
High Security Locks across Rolling Hills
Rolling Hills (ZIP 90274) is a single gated community reached from Palos Verdes Drive North through the Main Gate, with additional entries at Eastfield Gate and Crest Gate. Whether your home is in the Portuguese Bend Road area, the Eastfield Drive area or the Crest Road area, we plan the visit around gate clearance so we can reach you without delay on the private roads.
The housing here is mostly large single-family ranch estates, many from the 1950s and 60s, behind the white three-rail fencing the community is known for. Original locksets are common, and the hilltop fog and salt air can corrode exterior hardware over decades. That makes this a good moment to upgrade to a lock built to resist picking, bumping and drilling, paired with sturdier strike plates and frames where needed.
Equestrian properties add their own needs. Barns, stables and tack rooms hold valuable equipment, and the bridle trail network means people pass near property lines. We can key the house and outbuildings thoughtfully, with restricted keys for the people you trust. If you also run an electronic gate on your estate, we can discuss how the mechanical locks on your doors fit alongside it. Call (323) 997-8867 any time.
