Losing a key fob in Sierra Madre can happen in ways that are particular to the town. You park near Kersting Court for lunch and the fob is gone by the time you return. You spend a morning on the Mount Wilson Trail or in Bailey Canyon Wilderness Park and discover the fob fell out of a pocket somewhere along the way. Or the battery simply gives up one evening at the top of a steep Canyon lane. Whatever the cause, a car that will not recognize its key is a problem you want solved where the car sits.

Crenshaw Lock Company is fully mobile. We have no storefront for you to visit and nothing to tow your car to. David Shar and our technicians have served Greater Los Angeles and Ventura County since 1987, and we bring the equipment to your driveway, curb, or parking space in Sierra Madre. We replace and program remote key fobs, flip-style remotes, and smart or proximity keys for the vehicles we can support.

A replacement fob is not just a piece of plastic. Most modern vehicles need the new key to be electronically paired with the car, and in many cases the old, lost fob should be removed from the car's memory so that whoever finds it cannot use it. We walk you through what your specific vehicle needs, explain the options honestly, and tell you up front if something is outside what we can do on site.

How it works in Sierra Madre

  1. 1

    Call and describe the vehicle

    Phone (323) 997-8867 any hour. Tell us the make, model, and year, what kind of key you have or had, and where the car is parked. If you have a spare fob, mention that, since it can change how the job works.

  2. 2

    We drive to you

    Because we are fully mobile, we come to wherever the car is in Sierra Madre: a driveway on a quiet village street, a curb along Sierra Madre Blvd, or a pull-off near a trailhead. On narrow Canyon lanes we may park below and carry equipment up.

  3. 3

    Confirm ownership and identify the key

    Before cutting or programming anything, we verify that you are the owner or authorized user of the vehicle. We then identify the correct fob type, frequency, and chip or smart-key system for your car.

  4. 4

    Prepare and pair the new fob

    We provide a compatible fob, cut an emergency blade if your key has one, and program the remote functions and immobilizer pairing to the vehicle with our diagnostic and programming tools.

  5. 5

    Remove lost fobs and test everything

    Where the vehicle allows it, we erase the lost fob from the car's memory. Then we test lock, unlock, trunk, panic, and starting, and show you how the new fob behaves.

What affects the price

  • Vehicle make, model, and year, since some systems are far more involved to program than others
  • Type of key: basic remote, flip key, or smart and proximity key
  • Whether you still have a working fob to copy or all keys are lost
  • Whether a new emergency blade must be cut or a transponder chip programmed
  • Time of day and how far the car is from our dispatch, since we operate 24/7
  • Difficult access, such as a steep Canyon lane where equipment must be carried up

Key Fob Replacement across Sierra Madre

Sierra Madre is a compact foothill town, and where you park shapes how we work. In Downtown Sierra Madre, around Kersting Court and Mary's Market, cars sit on walkable village streets close to shops and cafes, which makes service quick to set up. Residents in ZIP code 91024 often tell us the fob went missing during an errand or while visiting the wisteria vine in bloom season, when parking fills up and attention is elsewhere.

Up in Sierra Madre Canyon, the lanes are narrow and steep, lined with old cabins and hillside homes. Cars are often parked tight against the road edge, and our van may need to stop lower down while we walk equipment to the vehicle. We plan for that, and it is one reason a clear description of where you are helps when you call. Homes in 91025 and the surrounding foothills may also have cars parked a bit away from the house, so tell us the nearest cross street.

Hikers get caught out too. If you lost a fob heading to Bailey Canyon Wilderness Park or the Mount Wilson Trail, we can meet you at the car. Main routes like Sierra Madre Blvd, Baldwin Ave, Michillinda Ave, and Sierra Madre Villa Ave, with the I-210 Foothill Freeway close by, are how we reach most of the town. Call (323) 997-8867 whenever you need us.

Key Fob Replacement in Sierra Madre — FAQs

Can you replace a key fob at my home in Sierra Madre Canyon?
Yes. We are fully mobile and work at the vehicle. If your lane is narrow or steep, we may park lower and carry equipment up. Call (323) 997-8867 and tell us where the car is.
I lost my only fob. Can you still make a new one?
In many cases yes, depending on the vehicle. All-keys-lost situations can involve more steps, and we will tell you honestly what your car requires. Call (323) 997-8867 to discuss it.
Do I need to tow my car to a dealer?
Often not. Because we come to you with programming equipment, many vehicles can be handled on site. Some models may be limited, and we will say so plainly rather than guess.
Will the lost fob still work after you program a new one?
Where the vehicle allows it, we can erase lost fobs from the car's memory so they no longer start or unlock it. Ask us about this when you call.
Can you help if my fob just stopped working?
Sometimes the fix is a battery or a re-sync, and sometimes the fob has failed. We can check which it is and replace and program a new one if needed.
Do you work at night or on weekends in Sierra Madre?
Yes, we are available 24/7. Call (323) 997-8867 any time, including after dinner in the village or after a late hike.
What information should I have ready when I call?
The make, model, and year of the car, the type of key you use, whether you have a spare, and your exact location in Sierra Madre. Have proof of ownership available, such as registration or ID.
Can you replace smart or proximity keys as well as simple remotes?
We work on remote fobs, flip keys, and many smart or proximity keys. Support depends on the vehicle, so give us your make and model and we will confirm what we can do.
