A car key problem rarely picks a convenient place. In Monrovia it might happen in a parking space along Myrtle Avenue after dinner in Old Town, in the lot at the Metro A Line station on a weekday morning, or at a trailhead near Monrovia Canyon Park after a hike. Crenshaw Lock Company is fully mobile, so we bring the tools, key-cutting equipment and programming gear to wherever you are stranded. There is no shop to tow your car to and no storefront to visit.
We have served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on the idea that a stuck driver needs clear answers and careful work. Our automotive service covers cars, trucks, motorcycles, RVs and fleet vehicles: opening locked doors without damage, cutting and programming replacement keys when every key is lost, extracting broken keys, and repairing worn ignitions and door locks.
Monrovia's mix of commuters, foothill residents, restaurant staff and visitors means we see a wide range of situations. Some people are locked out with a child or pet inside. Others have lost the only fob to a late-model vehicle and need a replacement that will actually start the car. Whatever the case, we explain what is involved before work begins, and we are available around the clock at (323) 997-8867.
How it works in Monrovia
- 1
Call and describe the situation
Phone (323) 997-8867 and tell us the make, model and year, where the vehicle is, and what happened: locked out, keys lost, key broken, or a car that will not start. If anyone or any animal is inside a locked car, say so right away so we can prioritize.
- 2
We confirm details and scope
We ask about the vehicle's key type, whether you have any working key, and what you can show us as proof of ownership. Based on that we explain what the job will likely involve so there are no surprises when we arrive.
- 3
We come to you
Because we are fully mobile and available 24/7, a technician drives to your vehicle, whether it is on a Myrtle Avenue block, a Huntington Drive curb, a hillside driveway, or the shoulder near the I-210 on-ramp. We do not make timing promises we cannot keep, but we do not stop for nights, weekends or holidays.
- 4
Verify ownership
Before opening or making a key for any vehicle, we check that you are the owner or authorized driver, typically with ID matched to registration or similar documents. This protects you and keeps the work legitimate.
- 5
Entry, cutting or programming
We use professional tools to open locked doors without scratching paint or damaging weatherstripping. For lost keys we cut a new key by code or by hand and program transponders or fobs to the vehicle on site, then test everything.
- 6
Test and hand over
We start the car, test the doors, trunk and remote functions, and confirm every key works. You get a clear explanation of what was done and advice on keeping a spare so you are not stranded again.

What affects the price
- Vehicle make, model and year, since many newer vehicles use encrypted transponder or smart-key systems that take more equipment and time than older mechanical keys.
- The type of service needed: a simple lockout, a duplicate key from a working original, an all-keys-lost replacement, or ignition and lock repair all involve different amounts of work.
- Key technology, such as a basic metal key, a transponder chip key, a remote head key, a laser-cut key or a proximity smart key.
- Time and location of the call, including late-night, weekend and holiday requests and how far the technician must travel within the service area.
- Number of keys needed and whether additional work is required, such as extracting a broken key or repairing a worn ignition cylinder.
- Special vehicle types like motorcycles, RVs, commercial trucks or fleet vehicles, which can have unusual lock systems or multiple units to service in one visit.
Why Monrovia chooses us
- Fully mobile 24/7 service: we come to you, so a lost key in Monrovia never turns into a tow to a shop.
- Operating since 1987, with David Shar as owner and lead technician, so the experience behind the work is long-standing and accountable.
- Broad vehicle coverage: cars, trucks, motorcycles, RVs and fleets, rather than a narrow focus on only common models.
- Damage-conscious entry methods and on-site key programming, so you do not need a dealership visit for a working replacement in many cases.
- Ownership verification on every job, which protects you from someone else getting a key to your vehicle.
- Plain explanations of what affects the cost before work starts, with no dollar guessing over the phone and no pressure.
Automotive Locksmith across Monrovia
Monrovia is a foothill city where driving habits vary block by block. Old Town Monrovia pulls in diners and shoppers along Myrtle Avenue, and street parking near the Aztec Hotel and Library Park means keys get locked in cars more often than you would think on a busy evening. Commuters who park near the Metro A Line station sometimes call us after a long day when a fob battery dies or a key goes missing. In ZIP code 91016, which covers much of the central city, we are often called to downtown streets and nearby residential blocks.
Up in North Monrovia, the foothills bring steeper driveways and quiet streets where help is not close at hand. Residents near Mountain Avenue and above Foothill Boulevard, as well as hikers and picnickers at Monrovia Canyon Park, can find themselves with a locked car and no easy way home. Our mobile setup is built for exactly that, and we serve ZIP code 91017 and the surrounding hillside areas as readily as the flats.
Mayflower Village and the corridors along Huntington Drive and Foothill Boulevard see a steady mix of family cars, work trucks and delivery vehicles. Drivers on the I-210 sometimes need help when a breakdown ends in a lost or broken key. Wherever the vehicle is in Monrovia, call (323) 997-8867 and we will come to you, at any hour.
