A transponder key looks like an ordinary key, but inside the plastic head is a small chip that talks to your car's immobilizer. If the chip's code does not match what the car expects, the engine will not start, even when the blade turns the ignition cylinder. That is why a hardware-store copy often opens the door but leaves you stuck. Programming is the step that teaches the car to recognize a key.
In Commerce, vehicles lead busy lives. People commute along the I-5, I-710 and SR-60, workers park at distribution centers and warehouses all shift, and visitors leave cars at the Citadel Outlets or Commerce Casino for hours. A lost or broken key in any of those places is a real problem, and it rarely happens at a convenient time. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile, so we bring the work to the car instead of asking you to tow it.
We have no storefront to visit. Every job is done where the vehicle sits, and we are available around the clock. Whether you need a spare made before you lose your only key, or you have lost every key and need a new one started from scratch, the process is straightforward when you know what to expect. Below is how we handle it, what affects the cost, and what is specific to working in Commerce.
How it works in Commerce
- 1
Tell us about the vehicle and the situation
Call (323) 997-8867 and give us the make, model and year, plus whether you still have a working key. That tells us whether you need an added spare or a replacement when every key is gone. We will explain the general path for your vehicle so you know what to expect.
- 2
Meet you where the car is
We drive to you, whether that is a driveway in Rosewood Park, a lot in the Citadel district, or a parking area near a warehouse off Washington Blvd. Because we are mobile, the car does not have to be towed anywhere.
- 3
Confirm ownership
Before we create a key for any vehicle, we ask for proof that it is yours, typically photo ID and registration or title. This protects you and every other driver. If something cannot be verified, we will say so plainly.
- 4
Prepare or cut the key
If the key needs a blade, we cut it to match the vehicle's locks. We then pair the transponder chip with the car. Some vehicles accept a new key while an existing key is present, and others require a full add-key procedure through the diagnostic port.
- 5
Program to the immobilizer
We connect to the vehicle and register the new key with the immobilizer so the engine will recognize it. This step is specific to each make and model year, and we adapt to what your car requires.
- 6
Test everything before we leave
We test the key in the door, the ignition and any remote functions. We also check each key you already had, so you leave knowing every key works. If a spare makes sense, we will suggest it.

What affects the price
- Make, model and year of the vehicle, since some immobilizer systems are far more involved than others.
- Whether you still have a working key (adding a spare) or have lost all keys, which changes the procedure and time required.
- The type of key: basic transponder blade, laser-cut key, flip key or smart proximity key all differ in parts and programming steps.
- Whether the key blade needs to be cut or the key is already cut and only needs programming.
- The number of keys you want made during the same visit.
- The time of day and location of the call, since after-hours and roadside service can differ from a scheduled daytime visit.

Transponder Key Programming across Commerce
Commerce is mostly an industrial city, and that shapes the calls we get. Around the BNSF Hobart intermodal rail yard and the many distribution centers and cold-storage buildings, people park work vehicles and personal cars for long shifts. A lost key at the end of a night shift in the 90040 area is a different problem from one at a quiet house, and our mobile setup is built for it. Fleet managers can also call us for spare keys on company vehicles, so one lost key does not sideline a driver.
Residential pockets such as Rosewood Park and Bandini have small post-war bungalows and tract homes where cars usually sit in driveways or on the street. If your only transponder key has gone missing, we can come to the curb, confirm ownership and program a replacement on site. The same goes for Bristow Park and the Citadel district, where visitors to the Citadel Outlets or Commerce Casino sometimes discover a broken or missing key long after dark.
We serve the ZIP codes 90040, 90091, 90022 and 90023, and we know the routes: Washington Blvd, Atlantic Blvd, Telegraph Rd and Eastern Ave, plus the I-5, I-710 and SR-60 corridors that cut through town. If you are stuck near the Commerce Library, a warehouse lot or the freeway on-ramps, call (323) 997-8867 and we will plan the visit around where you are.
