Losing the only key to your car is stressful anywhere, but in La Puente it tends to happen at inconvenient moments: in a shopping center lot on Hacienda Boulevard, outside a workplace off Valley Boulevard, or in your own driveway before a commute onto the I-10 or SR-60. A broken key that snapped in the ignition or door lock creates the same problem. The good news is that you rarely need a tow to a dealership to solve it.
Crenshaw Lock Company is a fully mobile locksmith. We have no storefront to visit; the shop comes to you. Our technicians cut the key blade and program the transponder or smart key to your vehicle at the curb, in a parking lot, or in your driveway. That works even when every original key is gone, which is the situation most people calling us are in.
David Shar has led the company since 1987, and the work has changed a great deal in that time. Plenty of older cars still run on a simple cut key, while newer vehicles need electronic programming, a push-button start fob, or a laser-cut blade. We sort out which one you have, explain the options plainly, and replace the key without sending you across town or leaving your car stuck.
How it works in La Puente
- 1
You call, we ask the right questions
Call (323) 997-8867 any hour. We ask for the make, model, and year of your vehicle, what type of key it used, and whether you have any working key left. That tells us what equipment to bring and whether the job involves a simple cut key, a transponder key, or a smart fob.
- 2
We come to your location
Because we are fully mobile, we drive to wherever the car is parked, whether that is a driveway in Hudson, a lot along Valley Boulevard, or a street near La Puente Park. There is no need to move or tow the vehicle first in most cases.
- 3
Verifying ownership
Before making a key, we confirm that the vehicle is yours. This typically means matching your identification to the registration or title. It protects you, and it is a standard step for any responsible locksmith.

Cutting the new key
Using the vehicle's information, we cut a fresh blade on site. If the car has a laser-cut or high-security key, we use the appropriate cutting method for it. If the original key broke, we can also remove the broken piece from the lock when needed.
- 5
Programming and testing
For vehicles with a transponder chip or smart key, we program the new key to the car's computer so it will start the engine. We then test the key in the door, trunk, ignition, and any remote functions before we leave.
- 6
Spare key and guidance
We recommend making a spare while we are already there, since duplicating a key is generally simpler than replacing one when none exist. We also explain how to store it safely so you are not stranded again.

What affects the price
- The type of key your vehicle uses: a basic cut key, a transponder key, a laser-cut key, or a push-button smart fob all involve different materials and labor.
- Make, model, and year, since some manufacturers require more involved programming procedures than others.
- Whether you have an existing key to copy or all keys are lost, which can change how much work is needed to generate a new one.
- How many keys you need, including a spare, and whether remote lock and unlock functions must also be programmed.
- The time of day and location of the call, since after-hours and nights or weekends can affect scheduling and travel.
- Any extra work such as extracting a broken key or repairing a worn ignition or door cylinder.
Why La Puente chooses us

- Available 24/7, which matters when a key goes missing late at night or before an early commute.

Car Key Replacement across La Puente
La Puente is a car-dependent community. Residents in neighborhoods like Hudson and Sunset, as well as nearby unincorporated Valinda and Bassett, rely on their vehicles to get to work, school, and errands along Valley Boulevard, Hacienda Boulevard, and Amar Road, and to reach the I-10 and SR-60. When a key goes missing, the disruption is immediate.
Much of the area is made up of 1950s and 1960s single-story tract homes with driveways and street parking, so many people discover a lost key right at home. Others are caught away from home, such as in the retail lots along the Valley Boulevard corridor or the Hacienda Boulevard strip, or after a stop at The Donut Hole. We drive to you in all of those places, serving ZIP codes including 91744, 91746, and 91747.
If you also have lock needs at your property, we can help with those too. Landlords with converted-garage ADUs sometimes ask us to rekey doors after a tenant change, and small shops along Valley Boulevard sometimes need storefront cylinders replaced. For your vehicle, call (323) 997-8867 and we will take it from there.
