Losing a key fob or watching one die is rarely convenient, and in La Cañada Flintridge it tends to happen at awkward moments: in the parking lot at Descanso Gardens, at the end of a long commute up the 210, or at the top of a steep driveway above Foothill Boulevard. Modern fobs are small computers, and replacing one involves more than cutting metal. The new fob must be matched to your vehicle's immobilizer system so the car recognizes it and, just as importantly, so a lost fob can be removed from the car's memory.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no storefront to drive to and no need to tow a car you cannot start. We bring the programming equipment and fob blanks to wherever the vehicle is parked, whether that is a hillside home in Flintridge, a street near Memorial Park, or a school lot near Flintridge Preparatory School. Owner and lead technician David Shar built the business on doing this kind of work properly.

This page explains how replacement works, what affects the cost, and what to have ready when you call. We do not quote prices without knowing your vehicle, because the right answer depends on the make, model, year, and type of key. A quick call to (323) 997-8867 is the fastest way to find out what your situation requires.

How it works in La Cañada Flintridge

  1. 1

    Tell us about the vehicle

    When you call, we ask for the make, model, and year, and whether you have a fob that still works. We also ask whether the car uses a push-button start or a traditional key slot. This lets us bring the right fob type and programming tools to your location in La Cañada Flintridge.

  2. 2

    Confirm ownership

    We verify that you own the vehicle or are authorized to have a key made for it. Registration or title, along with matching photo ID, is the standard way to do this. It protects you, because a fob is effectively a key to your car.

  3. 3

    Come to your location

    We are 24/7 and fully mobile, so we meet you where the car is. That could be your driveway in the Sagebrush area, a street off Verdugo Boulevard, or a parking space near JPL. Working on site means you never have to move a car that will not start.

  4. 4

    Prepare and pair the new fob

    We cut an emergency key blade if your fob includes one, then program the new fob to the vehicle's immobilizer and remote functions. For many vehicles we can do this even when every original fob is lost. Programming and testing are done at your car.

  5. 5

    Test everything and remove lost fobs

    We test lock, unlock, trunk, panic, and start functions. If a fob was lost or stolen, we can clear it from the car's memory when the vehicle supports that, so the missing fob stops working. We also leave you with advice on keeping a spare.

What affects the price

  • Vehicle make, model, and year: luxury and newer European models often use more complex, costlier fobs than a basic remote on an older domestic car.
  • Fob type: a simple remote, a flip key, and a push-to-start smart key differ in hardware and programming effort.
  • Whether you have a working fob: duplicating from an existing key is generally simpler than creating a first key when all fobs are lost.
  • Immobilizer security level: some vehicles need extra steps or specialized equipment to add a key.
  • Emergency key blade cutting: fobs with a hidden mechanical key need it cut and tested.
  • Time and location: after-hours, holiday, or hard-to-reach calls can affect the quote, which we explain before work starts.

Why La Cañada Flintridge chooses us

  • Fully mobile service: we come to the car, so there is no towing to a shop and no storefront trip.
  • In business since 1987, with David Shar as owner and lead technician.
  • Available 24/7, which matters when a fob fails at night or while you are stranded away from home.
  • We handle all-keys-lost situations as well as simple spares, instead of limiting work to easy duplicates.
  • Clear explanation of what we can and cannot program for your specific vehicle before we begin.
  • Lockout help and fob replacement from one provider, useful when a dead fob has also locked you out.

Key Fob Replacement across La Cañada Flintridge

La Cañada Flintridge is a hillside city split by the 210 Freeway, and that shapes how we work here. Long driveways and gated properties are common in Flintridge and up toward the Angeles forest, so we often program fobs right in the driveway where the car is parked. In Alta Canyada and the Sagebrush area, residents tend to own several late-model vehicles per household, which makes a spare fob, ideally made before one is lost, a practical idea.

People also lose fobs away from home. Visitors to Descanso Gardens or Memorial Park sometimes find a dead fob, a lockout, or a missing key, and commuters heading to NASA's JPL or along Foothill Boulevard can run into the same trouble at work. Whether you are in ZIP code 91011 or 91012, we can meet you at a parking lot, a street near Flintridge Preparatory School, or your own garage.

If you also want house keys, gate locks, or a high-security deadbolt looked at, we can do that on the same visit. Many homes here have perimeter and pedestrian gates alongside the front door, and it is easy to tidy up all of your keys at once. For the car, call (323) 997-8867 any hour.

Key Fob Replacement in La Cañada Flintridge — FAQs

Can you make a key fob if I have lost all of my keys?
In most cases, yes. We can often create a new fob from the vehicle's identification details and program it on site. Call (323) 997-8867 with your vehicle details and we will tell you what is possible.
Do you come to me in La Cañada Flintridge?
Yes. We are fully mobile and have no storefront. We come to your home, workplace, or wherever the car is parked, including hillside driveways and parking lots near Descanso Gardens.
Are you available at night or on weekends?
Yes, we are 24/7. If your fob fails late at night or on a holiday, call (323) 997-8867 and we will talk through next steps.
How much does a replacement fob cost?
It depends on the vehicle, the fob type, whether you have a working key, and the security system involved. We do not guess without knowing your car, but we give a clear quote before work begins.
Will the old lost fob still work after you program a new one?
On many vehicles we can erase lost fobs from the car's memory so they no longer start or unlock it. Support varies by make and model, and we will tell you what applies to yours.
Do I need to go to the dealer instead?
Usually not. A mobile locksmith can program many fobs without a tow or dealer appointment. Some unusual models are restricted, and we will say so up front rather than start work we cannot finish.
What should I have ready when you arrive?
Have your registration or title and photo ID, plus any working keys or fobs you still have. Knowing the VIN, which appears on the dashboard near the windshield, also helps.
Can you fix a fob that just stopped working?
Sometimes the fix is a battery or a re-sync, and sometimes the fob needs replacing. We can diagnose it and tell you honestly which it is. Call (323) 997-8867 to start.
