A key fob is easy to take for granted until it disappears. In Azusa that can happen in a lot of ways: a fob slips out of a pocket on a hike at the San Gabriel Canyon trailheads, gets left in a classroom at Azusa Pacific University or Citrus College, or simply stops working after years of daily use. Whatever the cause, being stuck without a working key is stressful, and a trip to a dealership is not always practical when your car cannot be driven there.

Crenshaw Lock Company is fully mobile. There is no shop to visit; we bring the equipment to wherever the vehicle is parked, whether that is a driveway in a post-war tract neighborhood, a garage in Rosedale, a lot off Foothill Blvd, or a spot near the Metro A Line station. We have served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on straightforward, honest work.

This page explains how fob replacement works, what affects the cost, and what to have ready when you call. Every vehicle is different, so we confirm details about your make, model and year before we start, and we tell you plainly what is and is not possible for your car.

How it works in Azusa

  1. 1

    Call and describe the situation

    Call (323) 997-8867 any time, day or night. Tell us the make, model and year of the vehicle, where it is parked, and whether you have any working key left. That tells us whether we are cloning an existing fob or creating a new one from scratch.

  2. 2

    We come to your vehicle

    Because we are fully mobile, the work happens where the car is: at home, at work, on campus, or in a parking lot along Azusa Ave or Alosta Ave. You do not need to tow the vehicle anywhere in most cases.

  3. 3

    Verify ownership

    Before we cut or program anything, we ask for identification and proof that the vehicle is yours, such as registration or title. This protects you and is a standard, responsible practice for any reputable locksmith.

  4. 4

    Cut the key and prepare the fob

    If your vehicle uses a physical blade or emergency key, we cut it by code or from the lock as appropriate. We then match the correct fob or smart key to your vehicle's frequency and chip requirements.

  5. 5

    Program and pair with the vehicle

    We connect programming equipment to the car and register the new fob so the immobilizer recognizes it. If an old, lost fob is a security concern, we can discuss removing it from the vehicle's memory where the system allows.

  6. 6

    Test every function

    Before we finish, we test lock and unlock, trunk or hatch release, panic, remote start if equipped, and push-button ignition. You should leave with every feature working and a clear idea of whether a spare is worth having made.

What affects the price

  • Vehicle make, model and year, since some brands use simple remote-and-chip keys while others use encrypted smart keys that need more specialized equipment.
  • Whether you have a working key to copy or all keys are lost, which changes how much programming and verification work is involved.
  • The type of fob: a basic remote head key, a flip key, or a proximity smart key with push-button start each differ in hardware cost.
  • Location and time of day, because after-hours or hard-to-reach locations may affect the service call.
  • Whether you need extras such as an additional spare, an emergency blade cut, or removal of a lost fob from the vehicle's memory.
  • Whether the fob is a genuine OEM part or a quality aftermarket option, where the vehicle allows both.

Why Azusa chooses us

  • Fully mobile service: we come to your car, so there is no towing to a dealership just to get a key made.
  • Available 24/7, including nights, weekends and holidays, because lost keys rarely happen at convenient hours.
  • In business since 1987, with owner David Shar leading the work and standing behind it.
  • We explain options honestly, including when a cheaper aftermarket fob will do and when an OEM part is the better choice.
  • We verify ownership before programming, which keeps your vehicle secure and keeps us on the right side of good practice.
  • We test every function before leaving, rather than just confirming the car starts.

Key Fob Replacement across Azusa

Azusa is a spread-out city, and fob problems show up in all of it. In Downtown Azusa along Azusa Ave, residents and business owners often park on the street or in small lots near the older brick buildings and bungalows, and a dead or lost fob can leave a car stranded right at the curb. We handle those calls on-site, and the same applies to anyone near the Metro A Line Azusa Downtown station who commutes and finds the fob missing at the end of the day.

Rosedale, the master-planned community in the foothills, has many newer vehicles with smart keys and push-button start, which tend to need more careful programming. Mountain Cove, the gated community at the canyon mouth, adds its own wrinkle: gate access means we coordinate with you so we can reach the vehicle without delay. If you are in ZIP code 91702 and are not sure where to start, call (323) 997-8867 and we will sort it out together.

Students and staff at Azusa Pacific University and Citrus College are another common group. Fobs get lost in dorms, gyms and cars shared among roommates, especially around semester turnover. Drivers heading up SR-39 into the Angeles National Forest, or traveling the I-210 and Foothill Blvd corridors, also sometimes lose a fob far from home. We come to wherever the vehicle is, anywhere in Azusa and the surrounding area.

Key Fob Replacement in Azusa — FAQs

Can you replace a key fob if I lost all my keys in Azusa?
Often, yes. An all-keys-lost situation takes more work than copying an existing fob, but we can usually create and program a new one on-site, depending on the vehicle. Call (323) 997-8867 with your make, model and year and we will tell you what is possible.
Do I have to tow my car to a dealership?
In most cases no. We are fully mobile and bring the programming equipment to your vehicle in Azusa. Some very new or unusual models may have restrictions, and we will be upfront about that when you call.
What is the difference between a remote fob and a smart key?
A remote fob typically has buttons for lock, unlock and trunk, and is often paired with a physical key that starts the ignition. A smart or proximity key lets the car detect it nearby and start with a push button. Smart keys generally require more specialized programming.
How much does a replacement fob cost?
It depends on the vehicle, the type of fob, whether you have a working key, and the time and place of service. We do not quote numbers on this page, but call (323) 997-8867 and we will walk through what applies to your car.
Do you work at night or on weekends?
Yes. We are available 24/7, including nights, weekends and holidays. We do not make claims about specific arrival times, but you can reach us any hour at (323) 997-8867.
What do I need to show you before you program a fob?
We will ask for photo identification and proof that the vehicle is yours, such as registration or title. This protects you from someone else getting a key to your car.
Can you program a fob I bought online?
Sometimes. Compatibility depends on the vehicle and the fob, and some online fobs are locked, used or incorrect for the car. It is worth calling us first so we can tell you whether the part will work before you spend money.
Should I remove my old fob from the car's memory?
If a lost fob could be found by someone else, removing it from the vehicle's memory is a good idea where the system allows it. We can discuss that during programming, and it is also a good time to have a spare made.
