A BMW key is more than a piece of metal. Modern 3 Series and 5 Series models use encrypted keys that talk to the car, and many use Comfort Access so the car unlocks and starts with the key nearby. When that key is lost, broken, or never had a spare made, a generic copy shop cannot help. That is where a locksmith who works on BMW systems matters.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. We have no shop for you to get your car to. We come to the vehicle in Altadena, whether it is parked in a driveway, on a hillside street, or at a trailhead lot. We cover a lost single key, adding a spare, and all-keys-lost situations, and we confirm the correct key for your car by its VIN.

How it works in Altadena

  1. 1

    Call and share your VIN

    Call (323) 997-8867 any hour. Tell us your BMW model, year, and where the car is parked. The VIN, found on the dash near the windshield or on your registration, lets us confirm the right key for your car.

  2. 2

    We come to your BMW

    Our mobile technician drives to your location in Altadena with the equipment needed. Nothing needs to be towed, and the work happens right at the vehicle.

  3. 3

    Verify ownership

    Before cutting or programming anything, we ask for proof that the car is yours, such as ID and registration or title matching the VIN. This protects you and every other BMW owner.

  4. 4

    Make and program the new key

    We prepare a key suited to your car, whether you have a spare, one working key, or none. Our process depends on the vehicle, and we do not guess. Comfort Access and encrypted keys are our specialty.

  5. 5

    Test everything

    We check that the key starts the car, locks and unlocks it, and works with any remote or keyless functions before we leave. We can also add a spare while we are there.

What affects the price

BMW keys across Altadena

Altadena is a community of hillside streets, older homes, and strong neighborhood ties, and BMW owners here park in all kinds of places. We help drivers in Janes Village, near Christmas Tree Lane along Santa Rosa Avenue, around the Altadena Country Club, and in The Meadows. Whether you are in ZIP 91001 or 91003, we come to you.

People here also visit Charles White Park, Farnsworth Park, and the Cobb Estate and Sam Merrill Trailhead, where a lost key or a dead fob can leave you stranded. Many Altadena families are rebuilding after the Eaton Fire, and we understand the stress that adds. We also do residential work, like rekeying seized, soot-fouled deadbolts on surviving Janes Village homes, so we can look after your car and your locks in one call.

BMW keys in Altadena — FAQs

What if I lost all my BMW keys in Altadena?
An all-keys-lost situation is something we handle regularly. Call (323) 997-8867 with your VIN and location. We come to the car, verify ownership, and make a new key on site, so no towing is needed.
Can you make a spare BMW key?
Yes. Having a spare made while you still have a working key is usually simpler than replacing everything after a loss. We can do it at your home, work, or anywhere in Altadena.
What if I have no original key at all?
That is fine. We work from the VIN and proof of ownership rather than from an existing key. Call (323) 997-8867 and we will explain what we need before we arrive.
What is the difference between a push-button and a bladed BMW key?
Push-button Comfort Access fobs let the car unlock and start with the fob nearby, while bladed keys use a cut blade as well as an electronic part. Which one your 3 Series or 5 Series uses depends on the model and year, which the VIN helps confirm.
How do you confirm the right key for my BMW?
We use your VIN to identify the key your specific car needs, rather than guessing from the model name alone. We also check your registration or title and ID before any key is made.
Do you work on both 3 Series and 5 Series?
Yes, we work on both, including Comfort Access and encrypted keys. If you are unsure what you have, just give us the VIN and we will sort it out.
Do I need to bring my car to you?
No. We are fully mobile and available 24/7. We come to your BMW anywhere in Altadena, including 91001 and 91003.
