Losing the only key to your car is a stressful moment anywhere, but in a small foothill town like Sierra Madre it has its own flavor. Maybe you came back from the Mount Wilson Trail or Bailey Canyon Wilderness Park and the key fell out of a pocket somewhere along the path. Maybe a fob stopped working after an evening on Kersting Court, or a key snapped in the ignition. Whatever happened, you need a new key that actually starts the car, not just one that turns in the door.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads our automotive work. We are a fully mobile operation. There is no storefront to visit and no need to tow your car to a shop. We bring the key cutting and programming equipment to wherever your vehicle is parked, whether that's a driveway off Sierra Madre Blvd, a curb near Baldwin Ave, or a trailhead lot.
A replacement key today is usually more than a piece of cut metal. Many vehicles use transponder chips, remote fobs, or smart proximity keys that must be electronically paired to the car's immobilizer. We cut the physical blade where applicable and program the electronics so the vehicle recognizes the new key. If you have no original at all, that is still a situation we handle regularly. Call (323) 997-8867 and we'll start by asking about your make, model, and year.
How it works in Sierra Madre
- 1
You call and describe the situation
Call (323) 997-8867 and tell us the make, model, and year of the vehicle, where it's parked, and whether you have any working key. We'll explain what type of key your car likely uses and what we'll need to verify before we start.
- 2
We come to your vehicle
Our technician drives to you. In Sierra Madre that might be a driveway near the village, a street in the Canyon, or a trailhead parking area. We are available 24/7 and there is no shop visit involved.
- 3
Ownership verification
Before making a key for any vehicle, we confirm you are entitled to it. That typically means matching your identification with the registration or title information. It protects you, and it protects the next person whose car could otherwise be taken.

Cutting the key
If your car uses a physical blade, we cut it on site using the vehicle's key code or by working from the lock itself when no original exists. Even with no key in hand, we can usually produce a working cut.
- 5
Programming and pairing
For transponder keys, remotes, and smart keys, we program the new key to the vehicle's computer so it starts the engine and, where applicable, operates locks and alarm functions. We can also address old keys if you want a lost one removed from the system.
- 6
Testing before we leave
We test the key in the door, trunk, and ignition, check any remote functions, and confirm the car starts and restarts properly. You should not be left guessing whether it will work tomorrow morning.

What affects the price
- Vehicle make, model, and year, since some manufacturers use far more complex security systems than others.
- Type of key needed: a basic cut key, a transponder key, a remote head key, a flip key, or a proximity smart key all involve different parts and programming.
- Whether you have any original key to copy, or whether we must create one from scratch because every key is lost.
- Whether the car must be unlocked first or the ignition or lock is damaged, for example from a broken key stuck inside.
- Time of day and location, since service is 24/7 but a late-night or hard-to-reach call differs from a daytime driveway visit.
- Number of keys you want made, because programming a spare during the same visit is generally more efficient than calling us back later.
Why Sierra Madre chooses us
- Fully mobile and on site: we bring cutting and programming tools to your car, so you never have to tow it or arrange a ride to a shop.
- In business since 1987, with automotive key work led by owner David Shar rather than handed off to an unknown call center.
- We can make keys even with no original, which matters when your only key is lost on a trail or left behind somewhere.
- We verify ownership before creating a key, which is a sign of a legitimate locksmith, not a hassle.
- Because we also do residential and commercial work, we can rekey a house or shop if a car key and a house key were lost together.
- Available around the clock, so a lost key at midnight does not have to wait until morning.
Car Key Replacement across Sierra Madre
Sierra Madre is compact and walkable, and that shapes how key emergencies happen here. Downtown Sierra Madre around Kersting Court is full of small shops, cafes, and visitors who park along the village streets, then wander for hours. A fob lost between a coffee stop and a stroll past the famous wisteria vine can leave a car stranded in the 91024 ZIP code. We come to wherever you parked and make a new key right there.
The terrain adds its own wrinkles. Sierra Madre Canyon, with its narrow, steep lanes of old cabins and hillside homes, can be tricky for any vehicle to reach, and cars are often parked tight along the road. Hikers heading to Bailey Canyon Wilderness Park or the Mount Wilson Trail, the route made famous by the Mount Wilson Trail Race first run in 1908, sometimes lose keys on the climb and return to a locked car or one that will not start. If you're in the 91025 area or anywhere nearby, tell us exactly where you're parked and we'll plan our approach.
Major routes like Sierra Madre Blvd, Baldwin Ave, Michillinda Ave, and Sierra Madre Villa Ave connect the town to the wider area, and I-210 (Foothill Fwy) runs nearby. If your key problem started on the freeway or a different city, we can still help in many cases. And if a lost car key was on the same ring as your house key, ask us about rekeying the locks on your Craftsman or bungalow as well. Call (323) 997-8867.
