Losing a car key is stressful anywhere, but in Topanga it can feel worse. Cell service can be patchy, the canyon roads are winding, and a tow truck or a trip down to a dealership means a long, slow drive on Topanga Canyon Boulevard. Crenshaw Lock Company is fully mobile, so we come to the car instead. We have no storefront to send you to; the work happens where your vehicle is parked.
Our approach to car key replacement is straightforward. We confirm the vehicle and your ownership, cut a new key by code or by working from the lock itself, and program it to the car's immobilizer system so it starts the engine. This works for a lost key, a snapped key, a worn-out key that barely turns, or a situation where you have no working key at all, including when there is no original to copy.
David Shar has run Crenshaw Lock Company since 1987, serving Greater Los Angeles and Ventura County. That is a lot of years of keys, ignitions, and odd situations, from trailhead parking to long private driveways. We are available around the clock, because a lost key rarely happens at a convenient hour.
How it works in Topanga
- 1
Call and describe the situation
Call (323) 997-8867 and tell us the make, model, and year of the vehicle, where it is parked, and what happened to the key. Lost, broken, stolen, and never-had-a-spare are all different, and knowing which helps us bring the right equipment.

We come to your vehicle
We are fully mobile and available 24/7. Whether the car is in a driveway off Old Topanga Canyon Road, near the Topanga Community Center, or on a pullout along the canyon, we travel to you. Tell us about any gate codes or tricky private road access in advance.
- 3
Verify ownership
Before making any key, we ask for proof that the vehicle is yours, typically a photo ID along with registration or title paperwork. It protects you, and it is the responsible way to handle vehicle access.
- 4
Cut the new key
Depending on the vehicle, we cut the key by code, by decoding the lock, or by another method suited to the key type. This can be done even when no original exists to copy.
- 5
Program to the vehicle
Most modern cars need the new key or fob paired with the immobilizer or computer. We program it on site and confirm that it starts the engine and that remote functions work, where applicable.
- 6
Test and hand over
We test the new key in the door, trunk if applicable, and ignition, then walk you through what works. If you want a spare made while we are there, it is far easier to do it in the same visit.

What affects the price
- Vehicle make, model, and year, since some systems are far simpler to work with than others.
- Key type: a basic mechanical key, a transponder key, a remote head key, a smart or proximity key, or a fob each involve different parts and programming.
- Whether you have any working key, as a lost-all-keys situation requires more work than copying an existing one.
- How many keys you need, including whether you want a spare made during the same visit.
- Time of day and your location, since after-hours calls and remote canyon driveways can affect the job.
- Condition of the ignition or locks, which occasionally need extra attention if they are worn or damaged.
Why Topanga chooses us
- Fully mobile: we come to the car, so you do not have to tow it or find a ride to a shop, and there is no storefront to visit.
- Available 24/7, including nights, weekends, and holidays, with no promises about arrival time we cannot keep.
- Lost-all-keys capability: we can make a working key when no original is available.
- Owner-run since 1987 under David Shar, so the experience behind each job is real and not borrowed.
- Honest about what is possible: if a particular vehicle needs dealer-only support, we will tell you plainly instead of starting a job we cannot finish.
- Familiar with canyon conditions: long private driveways, gates, and spotty cell service are normal here, and we plan for them.
Car Key Replacement across Topanga
Topanga is its own kind of place, and the way people lose keys here reflects it. A hiker finishes a loop in Topanga State Park and finds the key fob gone somewhere on the trail. A guest at an evening show at Theatricum Botanicum realizes their key is missing as everyone heads home. A resident in Fernwood discovers the spare they thought was in a drawer is nowhere to be found. In each case, the vehicle is often far from a dealership, and we bring the key work to you.
We serve the whole canyon, from the village area and the Topanga Community Center up through Old Topanga and the steeper roads toward Saddle Peak, and down toward the mouth of the canyon at Pacific Coast Highway. If you are in ZIP code 90290, call (323) 997-8867 and tell us where the car is parked. Many homes here sit down long private driveways, and some have gates, so a gate code or a description of the final stretch of road is helpful.
Canyon life is also hard on vehicles and keys: dust, moisture, and rough roads wear down older mechanical keys and fobs. If you are replacing one key, it is a good moment to ask about a spare, especially if you often park at trailheads such as Red Rock Canyon Park. And since we are a mobile service only, everything happens on site, wherever you are in Topanga.
