A key fob that stops working, goes missing, or gets dropped in a pool never picks a good moment. In Valencia that moment might be a parking lot at Westfield Valencia Town Center, a driveway in Bridgeport, or a dark stretch near the I-5 after a long shift. Our service is fully mobile, so there is no shop to tow your car to. We come to wherever the vehicle is parked and do the work there.

Key fob replacement covers more than most people expect. It can mean a basic remote that locks and unlocks doors, a remote-head key with a transponder chip, or a push-button-start smart key that your car detects by proximity. Each type is cut, paired, and programmed differently, and the right approach depends on your make, model, and year. We start by identifying exactly what your vehicle uses, then explain the options before any work begins.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead tech David Shar built the business on straightforward, honest work. If you have lost every key, we can often create a new one on site. If you still have one working key, the process is usually simpler. Either way, you get a clear explanation of what is happening with your car and why.

How it works in Valencia

  1. 1

    Call and describe your vehicle

    Call (323) 997-8867 any time of day or night. Tell us the make, model, and year, what kind of key you have or had, and where the car is parked. We will explain what information we need and whether you have a spare key available.

  2. 2

    We come to your location

    Because we are fully mobile, we travel to you, whether that is a Westridge driveway, a townhome parking spot near McBean Parkway, or a business park lot at the Valencia Industrial Center. There is no need to move the car or arrange a tow.

  3. 3

    Verify ownership

    Before we cut or program anything, we ask for proof that the vehicle is yours, typically a photo ID along with registration or title paperwork. This protects you and keeps the work responsible.

  4. 4

    Identify and prepare the new fob

    We confirm the correct fob or key type for your vehicle, including the transponder or proximity technology it needs. Where a physical blade is involved, we cut it to match your lock.

  5. 5

    Program and pair with the vehicle

    We connect to the car and pair the new fob so the doors, trunk, remote start, and engine immobilizer all recognize it. If old fobs are lost, we can often remove them from the system so they no longer work.

  6. 6

    Test everything before we finish

    We test lock, unlock, trunk, panic, and starting functions, and the physical key where there is one. You will leave with a working fob and a clear sense of how to care for it and why a spare is worth having.

What affects the price

  • Vehicle make, model, and year, since some brands use more complex security systems than others.
  • Type of fob: a basic remote, a remote-head key with a transponder, or a push-button-start smart key.
  • Whether you have a working key to copy or all keys are lost, which changes how the new key is created.
  • Whether a physical blade needs cutting and the lock style involved.
  • How many fobs you need programmed, and whether old lost fobs should be erased from the vehicle.
  • Time of day and location, since we serve customers 24/7 and travel to you.

Why Valencia chooses us

  • Fully mobile service: we work at your car, not in a shop, so a dead fob does not mean a tow.
  • In business since 1987, with owner and lead tech David Shar leading the work.
  • Available 24/7, including nights, weekends, and holidays, so a lost fob at midnight is not left until morning.
  • Clear explanation of options before work begins, so you understand what the vehicle needs.
  • We verify ownership before programming, which protects you from someone else getting a key to your car.
  • We also handle home and business locks, so one call covers the car, the townhome, or the office.

Key Fob Replacement across Valencia

Valencia is a car-centered community. Master-planned from 1965 by Newhall Land, it is laced with paseos but depends on I-5, McBean Parkway, Valencia Boulevard, Magic Mountain Parkway, and Newhall Ranch Road to get anywhere. Residents in Westridge, Northbridge, Valencia Summit, Tesoro del Valle, Bridgeport, and Old Orchard rely on keys and fobs daily, and a dead remote can strand someone in a garage or parking lot.

We serve both Valencia ZIP codes, 91354 and 91355. Typical calls include a parent at Westfield Valencia Town Center whose smart key stopped responding, a CalArts student who lost a fob on campus, or a visitor to Six Flags Magic Mountain who cannot get back into their car at the end of the day. We also help nurses and staff at Henry Mayo Newhall Hospital after long shifts, and fleet or work vehicles at the Valencia Industrial Center.

If you live in a gated community such as Westridge or Tesoro del Valle, we can meet you at your driveway or a guest area. Since many homes here have attached garages, some people also need a garage remote or home lock addressed at the same visit, and we can help with those too. Call (323) 997-8867 and we will come to you.

Key Fob Replacement in Valencia — FAQs

Can you replace a key fob if I lost all my keys?
In many cases, yes. We can often create and program a new key or fob on site even when no working key remains. It depends on the vehicle, so call (323) 997-8867 with your make, model, and year.
Do I need to tow my car to you?
No. We are fully mobile and come to your car anywhere in Valencia, whether that is a driveway, a parking structure, or a business park lot.
What kinds of fobs do you program?
We work with remote-head keys, standard remotes, and push-button-start smart or proximity keys. Compatibility depends on your vehicle, so we confirm before starting.
Is it cheaper than going to the dealer?
We cannot promise a comparison for every vehicle, but many customers choose us because we come to them and avoid towing. Cost depends on the factors above, and we explain them before work starts.
Do you work at night and on weekends?
Yes. We are available 24/7, including holidays. Call (323) 997-8867 any time you need a fob replaced.
What do I need to show to prove the car is mine?
Typically a government photo ID along with registration, title, or other paperwork linking you to the vehicle. We ask for this every time to protect owners.
Can lost fobs be deactivated?
Often yes. When we program a new fob we can usually erase old ones from the vehicle so a lost fob cannot be used to unlock or start the car.
My fob just stopped working. Do I need a new one?
Not always. Sometimes the battery is dead or the fob only needs reprogramming. We can diagnose it on site and tell you honestly whether a replacement is needed.
