Car trouble in Altadena rarely happens in a convenient spot. It might be a locked door at the Sam Merrill Trailhead after a long hike up toward the Cobb Estate, a dead key fob in the lot at Farnsworth Park, or a lost key on Lake Avenue after dinner. Because Crenshaw Lock Company is fully mobile, the work happens right where the vehicle is parked, whether that is a trailhead, a driveway or the side of Fair Oaks Avenue.
David Shar has run Crenshaw Lock since 1987, serving Greater Los Angeles and Ventura County. Our automotive work covers cars, trucks, motorcycles, RVs and fleets: opening locked vehicles, cutting and programming replacement keys, repairing worn or damaged ignitions, and helping when a key breaks off in a door or ignition. We answer around the clock, so a late-night lockout is not a problem we make you wait out until morning.
Altadena has its own rhythm right now. Many families are rebuilding after the January 2025 Eaton Fire, and that means more contractor trucks, work vans, trailers and second vehicles parked on temporary sites, and plenty of people driving unfamiliar rentals or borrowed cars. Keys get lost and locked inside more often when routines are disrupted. We understand that, and we try to make the call simple: tell us the vehicle, where you are, and we will explain what is involved.
How it works in Altadena
- 1
You call, we talk through the situation
Call (323) 997-8867 and tell us the make, model and year, where the vehicle is, and what happened: locked out, key lost, key broken, or a fob that stopped working. We will tell you what the job likely involves and what could affect the price before anyone drives out.
- 2
We travel to your vehicle
We are mobile only, so a technician comes to you, whether you are in a driveway in Janes Village, a jobsite lot along Woodbury Road, or a parking space near Charles White Park. We do not ask you to tow the car anywhere.
- 3
We confirm you are entitled to the vehicle
Before opening a door or making a key, we ask for reasonable proof of ownership or authorization, such as ID matched to registration or insurance. It protects you, and it protects every other driver in town from key-related theft.
- 4
We open, cut or program with care
For a lockout we use tools designed to open the vehicle without harming paint, weatherstripping or electronics. For keys, we cut and program to the vehicle's system, or repair the ignition or lock cylinder if wear is the root cause.
- 5
We test everything before we finish
We try every key and fob on the doors, trunk and ignition, confirm remote functions work, and make sure the vehicle starts and runs as it should. You should drive away with a working spare option discussed, not just a quick fix.

What affects the price
- Type of service: a simple lockout is a different job from cutting and programming a new transponder key or repairing an ignition cylinder.
- Vehicle make, model and year: newer and European models often use more complex security systems that need specific equipment and programming time.
- Key type: a basic mechanical key, a transponder key, a smart key or push-button fob each involve different parts and procedures.
- Whether all keys are lost: creating a first key from scratch generally takes more work than duplicating an existing working key.
- Time and location: after-hours or late-night calls, and sites that are harder to reach, can affect the final quote.
- Condition of the lock or ignition: worn, damaged or heat-affected components may need repair or replacement in addition to the key itself.
Why Altadena chooses us
- Fully mobile since 1987: no shop to visit, and no need to tow a vehicle just to get a key made.
- 24/7 availability, so lockouts at the trailhead or late-night breakdowns get an answer when you actually need one.
- Experience across cars, trucks, motorcycles, RVs and fleets, including the work trucks and trailers common on rebuild sites.
- Straightforward communication: we explain the factors that shape the price up front rather than surprising you afterward.
- Proof-of-ownership checks on every job, which is a sign of a legitimate locksmith rather than an inconvenience.
- Owner-led operation under David Shar, with a long local track record across Los Angeles and Ventura County.
Automotive Locksmith across Altadena
Altadena stretches from the flat grid near Lincoln Avenue and Lake Avenue up into the foothills, and cars end up in all kinds of places. Hikers park near the Sam Merrill Trailhead and the Cobb Estate area, families gather at Charles White Park and Farnsworth Park, and residents of Janes Village, The Meadows and the streets around Christmas Tree Lane on Santa Rosa Avenue depend on their vehicles daily. We serve both 91001 and 91003, and we come to wherever you are parked.
Since the Eaton Fire, many Altadena households are living between homes, driving rentals, or splitting time with temporary housing. Contractors are also coming and going on Altadena Drive, Woodbury Road and Fair Oaks Avenue with trucks, vans and equipment trailers. A lost key or a locked cab on a jobsite can stall a whole day, and we can help with replacement keys and lockout service for work vehicles and small fleets.
Steep, narrow hillside streets near the Altadena Country Club and the old Mount Lowe Railway area can make a stranded vehicle more stressful, especially at night. Call (323) 997-8867, tell us your location and the cross street or trailhead, and we will work out how to reach you. We can also handle locks on the home side if you are rebuilding, but for the car in front of you, we start with the vehicle.

- Christmas Tree Lane (Santa Rosa Avenue)
