Losing a key fob in Northridge rarely happens at a convenient moment. It slips out of a backpack between classes at CSUN, gets left in a shopping bag at Northridge Fashion Center, or finally dies after years of use in a car that has lived through plenty of Valley summers. When the fob stops working, the car may still be fine, but you cannot get in, start it, or trust it to lock behind you.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and David Shar and our technicians handle automotive key work as a fully mobile operation. There is no storefront to visit and no tow to arrange. We bring the equipment to your car, whether it is parked in a ranch-home driveway in the Devonshire residential area, in a student apartment lot off Reseda Blvd, or at a curb in Northridge Village.

Key fob replacement covers more than a plastic shell and a battery. Modern remotes and smart keys must be paired with the vehicle's immobilizer and computer, and the method differs by make, model, and year. We explain what your particular vehicle needs, what can be done on site, and what the options are before any work begins. We are available 24/7, so a late-night problem after an evening class or a shift at the hospital does not have to wait until morning.

How it works in Northridge

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us the make, model, and year, whether you have any working key left, and where the vehicle is parked. Whether you are in a CSUN lot or a driveway on Plummer St, we will tell you what to expect and what we need from you.

  2. 2

    We come to your vehicle

    We are fully mobile and available around the clock. A technician drives to your location in Northridge with cutting, programming, and diagnostic equipment, so the work happens where the car is parked.

  3. 3

    Verify ownership

    Before creating or programming a key, we ask for proof that the vehicle is yours, typically identification and registration or title. This protects you and is a standard part of responsible automotive locksmith work.

  4. 4

    Identify the right fob

    We confirm the correct fob or smart key type for your vehicle, including frequency, chip type, and whether it uses a flip blade, a push-start proximity system, or a separate remote. Choosing the right hardware first avoids a fob that looks right but will not pair.

  5. 5

    Cut, program, and pair

    We cut the emergency or blade key if your vehicle uses one, then program the transponder and remote functions to the car. Where the vehicle allows, we can also remove a lost fob from the system so it no longer works.

  6. 6

    Test everything before we leave

    We test lock, unlock, trunk or hatch, panic, and push-start or ignition operation. You leave with a fob that works, plus guidance on keeping a spare so you are not stranded again.

What affects the price

  • Vehicle make, model, and year, since some systems are far more complex to program than others
  • Type of key: a basic remote, a flip key with a transponder chip, or a push-button proximity smart key
  • Whether you have a working key to copy from or all keys are lost, which changes the programming method
  • Whether a blade must be cut or a key code obtained for your vehicle
  • Number of fobs needed, such as one replacement versus a spare alongside it
  • Time of day and location, because after-hours service is part of what we offer around the clock

Why Northridge chooses us

  • Fully mobile service: we come to the car in Northridge instead of asking you to tow it or find a shop
  • Available 24/7, including nights and weekends, which matters for students and shift workers around CSUN and Northridge Hospital
  • In business since 1987, with owner and lead tech David Shar behind the work
  • Honest guidance on whether a replacement fob, a repair, or just a new battery or shell is the right fix
  • Ownership verification on every automotive key job as a matter of routine
  • Testing of every function before we leave, so you are not discovering a dead panic button later

Key Fob Replacement across Northridge

Northridge is a spread-out part of the northwest San Fernando Valley, and cars here live a very car-dependent life. Commuters run Reseda Blvd, Nordhoff St, Balboa Blvd, and the Ronald Reagan Fwy (SR-118), and a lot of daily parking happens at the university, the Northridge Fashion Center, and Northridge Hospital Medical Center. Those are exactly the places where a fob gets dropped, locked in a car, or lost for good.

Students and staff in the CSUN district often deal with fobs lost in crowded lots, shared apartments, and busy move-in periods. In the Devonshire residential area, many households have several cars with older remotes that are finally wearing out, and a spare fob is often the smartest purchase. Over in Sherwood Forest, larger horsekeeping properties mean trucks and trailers parked well off the street, so a mobile technician who comes to the driveway saves a real hassle. We also serve Northridge Village and surrounding blocks.

We serve all Northridge ZIP codes, including 91324, 91325, 91326-area borders, 91327, 91328, and 91330, and we cover routes along Tampa Ave, Zelzah Ave, Lassen St, and Roscoe Blvd. Wherever your car is parked, call (323) 997-8867 and we will come to you.

Key Fob Replacement in Northridge — FAQs

Can you replace a key fob if I have lost every key to my car?
Often yes. All-keys-lost situations take more work than copying from an existing key, but a mobile technician can usually program a new fob on site. Call (323) 997-8867 with your make, model, and year and we will explain what applies.
Do I need to tow my car to you?
No. We are fully mobile and there is no storefront to visit. We drive to your vehicle anywhere in Northridge, including campus lots, apartment parking, and driveways, and do the work there.
Is key fob replacement available at night in Northridge?
Yes. We are available 24/7, including nights, weekends, and holidays. If you are stuck after an evening class or late shift, call (323) 997-8867.
Will you need proof that the car is mine?
Yes. We ask for identification and proof of ownership, such as registration or title, before making or programming a key. It protects you and any future owner of the vehicle.
What affects the cost of replacing a fob?
Mainly the vehicle make, model, and year, the type of fob or smart key, whether you have a working key, how many fobs you need, and the time of day. We discuss these factors with you before starting.
If my fob just stopped working, do I really need a new one?
Not always. A dead battery or worn shell is a common cause, and we will tell you honestly if that is the case. If the electronics have failed or the fob lost its pairing, replacement or reprogramming is the fix.
Can a lost fob be disabled so no one else can use it?
In many vehicles, yes. When we program new keys, we can often erase the old ones from the car's memory so a lost fob no longer works. Ask us about your specific vehicle when you call.
Should I get a spare fob while you are there?
It is usually a good idea, since adding a spare is simpler than starting from nothing after losing your only key. Mention it when you call (323) 997-8867 and we can plan for it.
