Losing a car key is stressful anywhere, but in San Dimas it often happens far from home: at a trailhead near Frank G. Bonelli Regional Park, after a day at Puddingstone Reservoir, in a parking lot off Foothill Blvd, or in the driveway of a ranch-style house when the only key has snapped in the ignition. Crenshaw Lock Company is fully mobile, so we come to wherever the car is sitting instead of asking you to have it towed to a shop.

Car key replacement covers several different situations: a lost key with no spare, a broken or worn key that still turns partway, a transponder key that no longer starts the car, or a fob that has stopped working. Each needs a slightly different approach, and many modern vehicles require the new key to be cut and then electronically programmed to the car before the engine will start. We handle both parts at your location.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are available around the clock, which matters when a lost key strands you late at night on Arrow Hwy or early in the morning before a commute onto the 210. We don't promise arrival times we can't control; we promise to pick up the phone, be honest about what your car needs, and do the work properly.

How it works in San Dimas

  1. 1

    Call and describe your vehicle

    Call (323) 997-8867 and tell us the make, model, and year, and whether you have any working key at all. We will ask where the car is parked in San Dimas and whether it is safe and accessible, so we can plan the right equipment before heading out.

  2. 2

    Confirm ownership

    Before making a key for a vehicle, we need to confirm that it is yours. That typically means matching your identification to the registration or title. This protects you and every other car owner in San Dimas.

  3. 3

    Determine the key type

    Some cars use a simple mechanical key, others a transponder chip, a remote head key, or a push-button smart key. We identify what your vehicle uses and explain the options before any work begins.

  4. 4

    Cut the key on site

    Using your vehicle's key code or by working from the lock itself, we cut a new key at your car. This works even when no original key exists, so a lost-all-keys situation does not have to mean a tow.

  5. 5

    Program to the vehicle

    If your car has an immobilizer, we program the new key or fob so the car recognizes it. We can often add a spare at the same visit, which is far easier than starting from scratch after a second loss.

  6. 6

    Test everything

    We test the key in the door, trunk if applicable, and ignition, and check remote functions. You should leave with a key that works every time, not one that barely starts the car.

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, transponder key, remote head key, or smart key each involve different parts and programming
  • Whether you have any working key, because lost-all-keys situations can require more steps than copying an existing key
  • Number of keys needed, as adding a spare during the same visit is usually more efficient
  • Time of day and location of the vehicle, since we are available 24/7 and travel to you
  • Condition of the ignition or locks, if a broken key fragment or worn cylinder needs extra attention

Car Key Replacement across San Dimas

San Dimas has a mix of settings where key trouble shows up. In the Via Verde hillside community in ZIP code 91773, residents often park in garages and driveways with tight turns, and a lost key can leave a car blocked in. We can work in a driveway or garage without disturbing neighbors, and if you are also moving into a Via Verde home, we can discuss other lock needs separately.

Around Downtown and Old Town San Dimas, with its western-facade buildings along Bonita Ave, cars are parked on the street or in small lots, and a key lost during dinner or an event can be a real headache. We come to the vehicle wherever it is parked in the 91773 area, whether near San Dimas Ave or Bonita Ave.

Out toward San Dimas Canyon and Bonelli Park, properties are larger and more rural, with gated drives, trucks, and work vehicles that get hard use. Keys are lost on trails, in barns, or near the water at Puddingstone Reservoir. If you are stuck near San Dimas Canyon Park or just off the 210, 57, or Foothill Blvd, call (323) 997-8867 and we will come to you.

Car Key Replacement in San Dimas — FAQs

Can you make a car key in San Dimas if I lost all my keys?
In most cases, yes. We can cut and program a new key on site even with no original. Call (323) 997-8867 with your vehicle details and we will tell you what is possible for your car.
Do I need to tow my car to get a new key?
Usually not. Our technician is fully mobile and comes to your vehicle in San Dimas, whether it is in a driveway, a parking lot, or near a trailhead.
What proof of ownership do I need?
We need to confirm the car is yours, typically with your identification matched to the registration or title. This protects owners from unauthorized key copies.
Is it cheaper than going to the dealer?
We won't make blanket claims, because it depends on the vehicle. Cost is driven by the car, key type, and situation. Call (323) 997-8867 and we can explain what applies to yours.
Can you replace a key fob or smart key?
Often yes. Many remote head keys, fobs, and smart keys can be replaced and programmed on site, depending on the make and model.
What if my key broke off in the ignition or door?
We can address broken key pieces and then make a replacement key. Avoid forcing the key, since that can damage the lock further.
Are you available at night or on weekends?
Yes, we are available 24/7. We do not give arrival time promises, but you can call (323) 997-8867 at any hour.
Can I get a spare made at the same time?
Yes, and we recommend it. Adding a spare during the same visit is usually simpler than dealing with another lost-key emergency later.
