A dead, cracked or missing key fob is a bigger problem than it looks. Many modern vehicles will not start, or will not unlock, without a properly programmed remote or proximity key. In San Marino, where many households run several late-model vehicles out of long driveways and garages, a lost fob can quickly disrupt the whole family's schedule.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no shop to tow your car to. We bring the equipment to wherever the vehicle is sitting, whether that is a driveway off Huntington Drive, a street near Lacy Park or a parking spot near the Huntington Library.

This page explains how fob replacement works, what affects the cost, and what to expect when you call. We will not guess at details over the phone that depend on your specific vehicle, so expect a few questions about the year, make and model before we plan the visit.

How it works in San Marino

  1. 1

    Tell us about the vehicle

    When you call (323) 997-8867, we ask for the year, make and model, the type of key you have (flip key, remote fob or push-button proximity key), and how many working keys remain. This tells us what hardware and programming tools the job needs.

  2. 2

    We come to your car

    Because we are fully mobile, a technician travels to your home, workplace or wherever the car is parked in San Marino. Nothing needs to be towed, and you do not need to find a shop.

  3. 3

    Verify ownership

    Before creating a new key, we confirm that you are the rightful owner using your ID and vehicle registration or other proof. It protects you and is a standard step for any responsible locksmith.

  4. 4

    Cut or prepare the key and fob

    If your vehicle uses a physical emergency blade, we cut it. We then prepare a replacement fob that matches your vehicle's required frequency and chip type.

  5. 5

    Program and pair with the vehicle

    We pair the new fob with the car's immobilizer and remote systems using professional programming equipment. Where the vehicle allows, we can also add a spare or remove a lost fob from the car's memory.

  6. 6

    Test every function

    Before we finish, we check locking, unlocking, trunk or hatch release, panic and starting functions. You leave with a fob that works and a clear understanding of what was done.

What affects the price

  • Vehicle make, model and year, since some brands need more complex programming than others
  • Type of key: a basic remote, a flip key or a push-to-start smart key each involve different parts
  • Whether you have any working key, since adding a key is often simpler than creating one when all are lost
  • Whether the vehicle's immobilizer system requires extra security steps or specialized equipment
  • Number of fobs needed, such as a spare plus a replacement
  • Time of day and location, because we are available 24/7 and the visit is mobile

Key Fob Replacement across San Marino

San Marino is a quiet, mostly residential city in the 91108 ZIP code, and our fob work here tends to happen in driveways and garages of large period-revival homes. Whether you live in the Huntington Library district, in the Lacy Park neighborhood or near the Mission District along Huntington Drive, we come to you with the programming tools in our vehicle.

Residents travel along Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue and Los Robles Avenue, and a fob can fail anywhere along them. If you are stranded at the Huntington Library, Lacy Park, the Crowell Public Library or near El Molino Viejo, call (323) 997-8867 and we will help.

We also work on the homes behind those cars. Many San Marino properties have original mortise locks and solid-wood doors, and we can rekey or service them as well. If a lost fob also means lost house keys, we can look at both in the same conversation.

Key Fob Replacement in San Marino — FAQs

Can you replace a key fob at my San Marino home?
Yes. We are fully mobile and come to your driveway, garage or wherever the car is parked. Call (323) 997-8867 to get started.
Do I have to tow my car to a dealer?
In many cases, no. We bring programming equipment to the vehicle. Some vehicles have special requirements, and we will tell you honestly if yours is one of them.
What if I lost all of my keys?
We can often create a new key and program it even when none work, though it usually involves more steps than copying from a working key. Call (323) 997-8867 and describe your vehicle.
Are you available at night or on weekends?
Yes, we are available 24/7. We do not make arrival time promises over the phone, but a technician will work with you on scheduling right away.
Does the new fob work like the original?
That is the goal. We test locking, unlocking, trunk release, panic and starting functions before we leave.
What do you need from me to program a fob?
We need to verify you own the vehicle, usually with ID and registration or similar proof. We also need the vehicle's year, make and model.
Can you add a spare fob while you are there?
Usually, yes. Having a spare programmed is often easier than replacing a lost one, and it can save you a future emergency.
How is the price determined?
It depends on the vehicle, key type, how many keys you need and whether any working key remains. Call (323) 997-8867 to talk through your situation.
