A dead or missing key fob rarely picks a convenient moment. In Pasadena it tends to happen in the parking structure by Old Pasadena after dinner, in a Caltech lot after a late lab session, or in the driveway of a bungalow just as you are leaving for the I-210. Crenshaw Lock Company is fully mobile, so we bring the equipment to wherever the car is sitting instead of asking you to get it towed to a dealership.

Key fob replacement covers a few different situations. Sometimes the fob still works but the case has cracked or the buttons are worn. Sometimes the battery or internal board has failed. Sometimes the fob is gone entirely and you have no working key at all. Each one calls for a slightly different approach, and part of our job is figuring out which one you have before anyone spends money on the wrong part.

We have served Greater Los Angeles and Ventura County since 1987, and David Shar, the owner and lead technician, built the business on straightforward service. We tell you what is involved, work at your vehicle, and test every function before we leave. We are available 24/7, and there is no storefront to visit; we come to you.

How it works in Pasadena

  1. 1

    Call and describe the vehicle

    Call (323) 997-8867 and give us the make, model, year and where the car is parked. Tell us whether you still have any working key, since that changes the approach. We will explain what to expect before we head out.

  2. 2

    Confirm ownership

    Before we cut or program anything, we ask for proof that the vehicle is yours, such as registration and matching photo ID. It protects you as much as us, because it keeps a stolen car from getting a new key.

  3. 3

    Identify the fob type

    We determine whether your car uses a basic remote with a separate key blade, a transponder key with remote buttons, or a push-button smart key. This decides the hardware we match and how it gets paired to the vehicle.

  4. 4

    Supply and prepare the replacement

    We provide a replacement fob suited to your vehicle, cut an emergency or door key blade when the design includes one, and prepare the unit for pairing. If a simple battery or case repair will do, we say so rather than selling you a new fob.

  5. 5

    Program on-site

    We connect to the vehicle and pair the new fob so the remote functions and engine start authorization all work. Depending on the vehicle, we may also add a spare or remove a lost fob so it no longer operates the car.

  6. 6

    Test everything

    Before we finish, we test lock, unlock, trunk or hatch, panic, and starting the engine with the new fob. You leave with a working key and a clear idea of how to care for it.

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 transponder key with buttons, or a proximity smart key
  • Whether you still have a working key to copy or all keys are lost, which can change the programming required
  • How many fobs you need, including whether you want a spare while we are already on-site
  • Whether an emergency key blade must be cut and whether the old fob needs to be removed from the vehicle's memory
  • Time of day and location, because we are available around the clock and travel to you

Why Pasadena chooses us

  • Available 24/7, including nights and weekends when dealerships are closed
  • We check what is actually wrong first, so a worn battery or cracked case does not turn into an unnecessary full replacement

  • We test every function before leaving and can add a spare so you are not stranded again

Key Fob Replacement across Pasadena

Pasadena's mix of neighborhoods shapes how fob calls go. In Old Pasadena and the Playhouse District, people often park in structures or along Colorado Boulevard and Fair Oaks Avenue for dinner or events, and a failed fob can leave a car stuck far from home. Near Caltech and along Lake Avenue, students, researchers and hospital staff from Huntington Hospital work odd hours, so a fob that quits at night needs a provider who actually answers after dark.

In residential areas like Bungalow Heaven, Madison Heights and Garfield Heights, cars usually sit on narrow driveways or street parking in front of Craftsman homes, and we can handle the programming right there. Up in Hastings Ranch, wider driveways make on-site work easy. We serve ZIP codes including 91101, 91103, 91104, 91105, 91106 and 91107, and event days around the Rose Bowl or the Rose Parade route can make traffic heavy, so give us a precise location when you call.

If you also deal with old hardware at home, we can help there too. Bungalow Heaven and the nearby historic streets are full of original mortise and rim locks, and we can rekey those while preserving the brass. For your car, though, the focus is simple: a fob that works, a spare in your pocket, and no tow truck. Call (323) 997-8867 whenever you need us.

Key Fob Replacement in Pasadena — FAQs

Can you replace a key fob if I lost every key to my car in Pasadena?
Yes, in many cases. An all-keys-lost situation takes more work than copying an existing fob, but we can usually make and program a new one at your vehicle. Call (323) 997-8867 with your make, model and year and we will explain what applies.
Do I have to tow my car to a dealership?
Usually not. We are fully mobile and bring the programming equipment to wherever the car is parked, whether that is a driveway in Madison Heights or a lot near Caltech.
Is the problem my fob or just the battery?
Often it is only the battery, or a worn case or button pad. We check this first and tell you honestly if a simple fix will do, so you do not pay for a new fob you did not need.
What proof of ownership do you need?
We ask for registration or title along with matching photo ID. This is standard practice and keeps someone else from getting a key to your car.
Can you program a smart or push-button key?
We work on many proximity and push-button start systems, though coverage depends on the specific vehicle. Call (323) 997-8867 and give us the details so we can confirm before we come out.
Can you make a spare while you are there?
Yes. Adding a spare while we are already programming is usually easier than a separate call later. We can also remove a lost fob so it no longer starts or unlocks the car.
Are you available at night or on weekends?
Yes. We are available 24/7, so a dead fob after an Old Pasadena dinner or a late night at the lab can still be handled. There is no storefront, since we come to you.
How much will replacement cost?
It depends on your vehicle, the type of fob, how many you need and whether you still have a working key. We discuss these factors up front so the process is clear before work begins.
