Losing a BMW key is stressful anywhere, but in Sierra Madre it often happens at a trailhead, a downtown parking spot, or at home on a steep canyon street. BMW keys are encrypted, and Comfort Access models add keyless entry and push-button start, so a hardware-store copy will not do the job. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and BMW Comfort Access and encrypted keys are our specialty.
We are 100% mobile. There is no shop to tow your car to: our technician drives to wherever your 3 Series or 5 Series is parked, verifies ownership, and works from the VIN to confirm the correct key for your exact vehicle. Whether you have lost your only key, want a spare before you lose it, or have no original at all, we can walk you through the options on the spot.
How it works in Sierra Madre
- 1
Call and share your vehicle details
Call (323) 997-8867 any hour. Tell us the model (3 Series or 5 Series), the year if you know it, where the car is, and whether you have any working key left. We will explain what to expect before we head out.

We come to your BMW
Our van meets you at your car in Sierra Madre, whether it is on a downtown street, in a driveway, or at a trailhead lot. Nothing needs to be towed.
- 3
Verify ownership and confirm the key by VIN
We check your ID and proof of ownership, then use the VIN to confirm the correct key type for your car. We never guess from the badge alone, since BMW keys vary by model and year.
- 4
Cut, program and test
We prepare the key for your vehicle, whether it is a bladed key or a push-button Comfort Access key, and pair it with the car. We then test locking, unlocking and starting before we finish.

Spare and next steps
If you were down to one key or none, we recommend having a spare made at the same visit so you are not stranded again.
What affects the price
- Whether you have a working key (spare) or all keys are lost, since all-keys-lost work is more involved
- Push-button Comfort Access key versus a traditional bladed key for your model and year
- How many keys you need made in one visit
- Your exact vehicle as confirmed by VIN, including model and year
- Time of day and how hard the car is to reach, such as a late-night call or a tight canyon street
BMW keys across Sierra Madre
Sierra Madre is compact, but BMW owners here get stuck in very different places. In Downtown Sierra Madre around Kersting Court, a lost key often turns up after a stop at Mary's Market or a meal and a stroll under the wisteria vine. In Sierra Madre Canyon, narrow lanes and steep grades mean we may park below and bring the equipment to your car on foot. We serve ZIP code 91024 and the canyon area in 91025.
Hikers also call us from near Bailey Canyon Wilderness Park and the Mount Wilson Trail, where a key can go missing in a pocket or on the trail. Wherever your 3 Series or 5 Series is parked, we come to you around the clock. We also handle home and shop lock work in town, but this page is about getting you back in your BMW with a key that is confirmed by VIN.
