Losing a key fob is a particular kind of headache. The car may be perfectly fine, but without the remote or proximity key it will not start, or you are stuck with a worn-out fob that locks and unlocks only when it feels like it. In a small, hilly city like Signal Hill, where many residents commute out through Cherry Ave or the I-405 every day, a dead fob can derail the whole day quickly.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar leads the work. We are fully mobile, meaning there is no shop to tow your car to. We bring the equipment to wherever the vehicle is parked: a driveway on the hill, a townhome garage, a street spot near Discovery Well Park, or a lot along the auto corridor.

We replace and program remote key fobs, flip-style remotes, and smart or proximity keys. That includes the situation where you have lost every key and need a new one created from scratch, as well as the simpler case where you have a working spare and just need a duplicate. We will tell you what your particular vehicle requires before any work begins.

How it works in Signal Hill

  1. 1

    Call and describe the situation

    Phone us at (323) 997-8867, any hour. Tell us the make, model, and year, whether you have any working key left, and where the car is parked. This lets us plan the right fob and equipment before we arrive.

  2. 2

    Confirm the vehicle and your ownership

    On site, we verify that the car is yours by checking identification and registration or similar proof. This protects you, and it is a standard step for responsible key work.

  3. 3

    Identify the correct fob type

    Fobs vary widely: basic remotes, remote head keys, flip keys, and push-button-start proximity keys. We match the frequency, chip type, and button layout to your vehicle so the new unit actually works as the original did.

  4. 4

    Cut the key blade if needed

    If your fob includes a mechanical blade or an emergency key, we cut it on site. Many modern proximity fobs have a hidden blade that still matters when the battery in the fob or car is weak.

  5. 5

    Program the fob to your vehicle

    We pair the transponder and remote functions with the car's computer so it starts and the lock, unlock, trunk, and panic buttons respond. If you lost all keys, older programmed keys can usually be removed from the car's memory if requested.

  6. 6

    Test everything before we leave

    We test starting, remote functions, and the physical blade in front of you, and we show you how to use any spare. You leave with a working fob and a clear understanding of what was done.

What affects the price

  • Vehicle make, model, and year, since some brands use far more complex security systems than others
  • Type of fob: a basic remote, a flip key, or a push-button-start smart key all involve different parts
  • Whether you have a working key to copy or all keys are lost, which changes the programming procedure
  • Whether a mechanical blade must be cut or an emergency key is included
  • Time of day and location, because we are available around the clock and travel to you
  • Whether you need one fob or additional spares programmed in the same visit

Why Signal Hill chooses us

  • Fully mobile service: we work at your vehicle, so you never need to arrange a tow just to get a key made
  • Operating since 1987 under owner and lead technician David Shar, with a long track record on automotive and residential lock work
  • Open 24/7, which matters when a fob fails late at night or before an early commute
  • Straightforward explanations of what your vehicle requires, with no pressure to buy options you do not need
  • Experience with both everyday vehicles and dealership-style lost-key situations, including inventory cars needing fobs
  • We also handle home and property locks, so one call can cover a smart-lock problem at the townhome too

Key Fob Replacement across Signal Hill

Signal Hill sits on a hill entirely surrounded by Long Beach, and its layout shapes how people use their cars. In the Hilltop area near Hilltop Park, many residents live in 1990s and 2000s townhomes and condos with tight garages and guest-only street parking. A fob failure there often means a car stuck in a garage or a parking space you cannot easily leave. We come to you, including along Panorama Promenade routes and nearby streets, and handle programming on site in ZIP code 90755.

The Discovery Well district, near Discovery Well Park where oil was discovered in 1921, mixes older homes with newer hillside developments. Drivers here often rely on Spring St, Willow St, and California Ave to get around, and a lost fob can strand someone far from a dealer. Because we are mobile, we meet you at your home, workplace, or wherever you parked.

Then there is the Cherry Avenue auto corridor and the Signal Hill Auto Center. Dealerships and used-car lots sometimes need a lost-key or fob programmed for an inventory vehicle or a customer car. We can support that kind of work, and our experience also covers the property side, from gate locks to smart-lock reprogramming at hillside homes, if you need it handled in the same visit.

Key Fob Replacement in Signal Hill — FAQs

Can you replace a key fob if I have lost all my keys in Signal Hill?
In many cases yes. We can create a new key and program it to your vehicle even when no working key exists. Call (323) 997-8867 with your make, model, and year and we will explain what your car requires.
Do I need to tow my car to you?
No. We are fully mobile and come to wherever the car is, whether that is a hillside garage, a street near Hilltop Park, or a lot on Cherry Ave. There is no storefront to visit.
Are you available at night or on weekends?
Yes, we operate 24 hours a day, 7 days a week. If your fob stops working late at night, call (323) 997-8867 and we will help.
Can you program a push-button-start smart key?
Yes, we replace and program smart and proximity keys as well as standard remotes and flip keys. Compatibility depends on the vehicle, so we confirm details before starting work.
Do I have to prove I own the car?
Yes. We ask for identification and proof of ownership, such as registration, before making or programming a key. This protects owners from unauthorized access.
Is it cheaper to replace a fob than go to a dealership?
We will not make claims about specific savings, since costs vary by vehicle. The main advantage is convenience: we come to you, so you avoid towing. Describe your car at (323) 997-8867 for guidance.
Can you just fix my fob instead of replacing it?
Sometimes a fob only needs a new battery or a re-sync, and we are glad to tell you if that is the case. If the case, buttons, or internal board are damaged, replacement is usually the better option.
Can a dealership on Cherry Ave use your service for inventory vehicles?
Yes, lost-key and fob programming for dealership inventory or customer vehicles is something we can assist with. Contact us to discuss the vehicles involved and how best to schedule the work.
