Losing the only key to your car is stressful, and in Cerritos it tends to happen in the middle of a normal day: a quick stop at Los Cerritos Center, an evening show at the Cerritos Center for the Performing Arts, or a long workday along South St or Bloomfield Ave. You do not need to arrange a tow or wait for a dealership appointment. Crenshaw Lock Company is fully mobile, so the work happens wherever the car is parked.
Modern car keys are more than a piece of cut metal. Most vehicles built in the last couple of decades use a transponder chip, a remote fob, or a push-button smart key, and each has to be matched electronically to the car before it will start the engine. We cut the blade when one is needed, program the chip or fob to your vehicle, and test everything before we leave: door locks, remote functions, and ignition.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987 under owner and lead technician David Shar. That experience matters when a situation is not routine, such as an all-keys-lost vehicle, a worn key that has started to fail, or a fob that has stopped responding. We are a mobile service only, with no storefront, which keeps the focus on getting to you and finishing the job where you are.
How it works in Cerritos
- 1
Call and describe the situation
Call (323) 997-8867 and tell us the make, model, and year, and whether you have any working key. We are available 24/7, and we will explain what the job involves and what affects the cost before we begin.
- 2
We come to your vehicle
Because we are fully mobile, we meet you wherever the car is: a driveway in a Cerritos neighborhood, a mall parking structure, a dealership lot, or the side of the road near the SR-91 or I-605.
- 3
Verify ownership
Before cutting or programming anything, we ask for reasonable proof that the vehicle is yours, such as ID matched to registration or insurance. This protects you and keeps keys out of the wrong hands.
- 4
Cut the key blade
If your car uses a physical blade, we cut it on site using the vehicle's key code or by working from the lock itself when there is no original to copy.
- 5
Program the transponder or fob
We pair the new key or fob with your vehicle's immobilizer system so it starts the engine and operates remote functions. Where applicable, we can also clear lost keys from the system so they no longer work.
- 6
Test everything before we leave
We try the key in the door and ignition, check remote lock, unlock, and trunk functions, and make sure you are comfortable with the new key before the job is complete.

- Vehicle make, model, and year, since some systems are far more involved to program than others

Car Key Replacement across Cerritos
Cerritos is a master-planned city with a car-centered layout, and that shapes how key problems show up. Cerritos Auto Square draws shoppers and owners from across the region, and a lost fob or the only key to a newly bought vehicle is a common reason people call us. On-site transponder and fob programming, plus a replacement cut, can often be handled right in the lot without a tow.
Around Los Cerritos Center and the Cerritos Towne Center area, parking lots and structures are busy at all hours, and keys get locked in cars, dropped, or misplaced during shopping and dining trips. The Civic Center area, with the Cerritos Library, the Sculpture Garden, and the Cerritos Center for the Performing Arts, brings evening events where a missing key can end the night. Residents of the two-story tract homes and townhome communities across ZIP code 90703 can also have us come to the driveway or guest parking space.
Whether you are stranded near Del Amo Blvd, South St, or Bloomfield Ave, or just off the SR-91 or I-605, call (323) 997-8867. We are mobile only, so there is no shop to drive to; we come to you anywhere in Cerritos.
