Losing a car key in Pomona rarely happens at a convenient moment. It happens in the Cal Poly Pomona parking structures after a late class, outside a restaurant on Antique Row on 2nd Street, in the lot at Pomona Valley Hospital Medical Center after a long shift, or in a driveway in Phillips Ranch with the morning commute waiting. Whatever the setting, the goal is the same: get you a working key without a tow truck and without a trip across town.

Crenshaw Lock Company is fully mobile, so there is no shop to visit. David Shar and our technicians have served Greater Los Angeles and Ventura County since 1987, and we bring the key cutting and programming equipment to wherever your car is parked. That matters in a city crossed by the I-10, SR-60, SR-57 and SR-71, where a stranded vehicle can be a long way from any dealership.

Car key replacement covers more than one situation. You may have lost every key and have nothing to copy. You may have a transponder key that snapped in the ignition, a fob with a dead board, or a worn key that barely turns. We work through each case on site, and we will explain what your particular vehicle needs before we start so there are no surprises.

How it works in Pomona

  1. 1

    Call and describe the situation

    Call (323) 997-8867 any hour. Tell us the make, model and year, whether you have any working key left, and exactly where the car is, whether that is a Holt Ave parking lot, a campus lot or your own driveway. We are 24/7 and mobile, so we plan the visit around your location.

  2. 2

    Confirm the vehicle and your ownership

    When we arrive, we verify that the vehicle is yours before cutting anything. Expect to show identification and proof of ownership or registration. This protects you, and it protects every other car owner in Pomona.

  3. 3

    Identify the key type

    Modern keys differ: traditional mechanical keys, transponder keys with a chip, laser-cut or high-security keys, and remote fobs or push-button start systems. We determine which one your car uses so the replacement is the right match, not a guess.

  4. 4

    Cut the key on site

    Using your vehicle's lock or key code information, we cut a new key by code, even when no original exists. Because we work from your car, you do not have to be towed anywhere to get a blank cut.

  5. 5

    Program and sync to the vehicle

    Transponder and fob keys must be programmed so the car recognizes them. We do this at your vehicle with our diagnostic equipment, then test the remote functions, ignition and door locks.

  6. 6

    Test and hand over

    Before we leave, we start the car, lock and unlock it, and check every new key. If you want a spare while we are there, we can usually make one in the same visit, which is far easier than going through this again.

What affects the price

  • Vehicle make, model and year, since some brands use far more complex security systems than others.
  • Key type: a basic mechanical key, a transponder key, a high-security laser-cut key, or a smart key with push-button start each involve different parts and work.
  • Whether you have a working key to copy or all keys are lost, which changes how much code and programming work is needed.
  • How many keys you want made, including whether you add a spare during the same visit.
  • Time of day and your location, because after-hours and distant calls involve different travel and scheduling.
  • Whether a damaged ignition or lock must be repaired in addition to making the key.

Why Pomona chooses us

  • Fully mobile service: we cut and program at your car, so you avoid a tow and a dealership wait.
  • In business since 1987, with owner and lead technician David Shar directing the work.
  • Available 24/7, including nights, weekends and holidays, which suits Cal Poly students, hospital staff and event workers on odd schedules.
  • Keys cut by code even when no original key exists.
  • Plain explanations of what your car needs before work begins, with no invented urgency.
  • Experience across locks of every age, from modern car cylinders to the older hardware found in Pomona's historic homes, so we can also help if your house key went missing with the car key.

Car Key Replacement across Pomona

Pomona is a city of distinct pockets, and car key problems show up differently in each. In the Downtown Pomona Arts Colony, evening visitors to the dA Center for the Arts and Antique Row on 2nd Street often park on the street and lose keys in the crowds. In Phillips Ranch and Ganesha Hills, the issue is more often a driveway call, such as a spare that was never made or a fob that stopped responding. Westmont and the neighborhoods near Garey Ave see plenty of daily commuters who depend on one key.

Students and staff around Cal Poly Pomona and Western University of Health Sciences have their own pattern: a key lost in a campus lot or a shared rental, and a car they need running for class or clinical shifts. If you are in ZIP code 91768 or 91767 and are stuck, call (323) 997-8867 and we will come to the car. We also serve 91766 and 91769 and the surrounding area.

During LA County Fair season, the Fairplex area gets busy with vendors, exhibitors and visitors, and a lost key in a crowded lot is a real headache. We reach drivers along Holt Ave, the I-10, SR-60, SR-57 and SR-71 corridors. If you also hold a Lincoln Park Historic District home with original mortise locks, mention it when you call; we handle both vehicle and period hardware work.

Car Key Replacement in Pomona — FAQs

Can you make a car key if I have lost every key?
Yes. We cut keys by code and program them on site, even when no original exists. After verifying ownership, we create a new working key at your car in Pomona. Call (323) 997-8867 to get started.
Do I need to tow my car to a dealership?
Usually not. We are fully mobile and bring the cutting and programming equipment to your vehicle, so a tow is generally unnecessary for key replacement.
Are you available at night and on weekends?
Yes, we are 24/7. Lost keys after a late class at Cal Poly Pomona or after an event at Fairplex are no problem. Call (323) 997-8867 any time.
What proof do I need to show?
We need to confirm the car is yours, typically with a photo ID and registration or other proof of ownership. We will not cut a key without that verification.
How much does car key replacement cost?
It depends on the vehicle, key type, whether you have a key to copy, how many keys you want and your location. Call (323) 997-8867 with your car details and we will explain what applies to your situation.
Can you replace a broken key stuck in the ignition?
Often yes. We can extract the broken piece and make a new key. If the ignition itself is damaged, we will tell you what repair is needed.
Do you program key fobs and push-button start keys?
We program many transponder keys, remotes and smart keys. Tell us your make, model and year when you call so we can confirm we can handle your system.
Should I get a spare key while you are there?
It is a good idea. A spare is simpler to make while we are already working on your car, and it protects you from repeating this situation. Ask us when you call (323) 997-8867.
