Losing the only key to a Hyundai Elantra or Sonata is stressful, whether you are parked off Myrtle Avenue in Old Town or at a trailhead near Monrovia Canyon Park. Crenshaw Lock Company is fully mobile. We have no shop for you to get towed to; we come to the vehicle and handle the key work on the spot.
Many Hyundai Elantra and Sonata models use a transponder key, while others use a push-button Smart Key fob, and the right type depends on the year and trim. We have served Greater Los Angeles and Ventura County since 1987, and we cover lost keys, adding a spare, and all-keys-lost replacement for Monrovia drivers any hour of the day or night.
How it works in Monrovia
- 1
Call and share your vehicle details
Call (323) 997-8867 and tell us your Hyundai model, year, and where it is parked in Monrovia. We will ask for the VIN and proof of ownership, which we use to confirm the correct key for your car.
- 2
We come to your car
A technician drives to your vehicle, whether it is in a driveway, a street spot in Old Town, or a lot near the Metro A Line station. Everything is done at the car, so there is no towing.

Key cut or prepared for your Hyundai
Depending on your model, we prepare a bladed transponder key or a Smart Key fob matched to your vehicle by VIN. If you have lost every key, we can still create a new one.

Programming and testing
We program the new key to your Hyundai and test it thoroughly: door locks, ignition or push-button start, and remote functions. We can also add a spare so you are not caught out again.
What affects the price
- Key type: a basic transponder key and a push-button Smart Key fob involve different parts and work.
- All keys lost versus adding a spare: having no working key generally takes more work than copying from one you still have.
- Model and year of your Elantra or Sonata, which determines the exact key and programming needed.
- Number of keys you want made, since adding a spare during the same visit is often more efficient.
- Time and location of the call, including after-hours service, since we are available 24/7.
Hyundai keys across Monrovia
Monrovia is a mix of walkable and hilly areas, and Hyundai owners call us from all of them. In Old Town Monrovia, we get calls from drivers near Myrtle Avenue, the Aztec Hotel, and Library Park, where a lost key after dinner or a farmers' market visit can strand you. In Mayflower Village, it is often a key lost at home or a spare needed for a family driver. ZIP code 91016 covers much of the central area, and we serve it around the clock.
Up in North Monrovia along the foothills, and in ZIP 91017, steep streets and long driveways make a tow especially inconvenient, so mobile service is a real advantage. Hikers heading to Monrovia Canyon Park and commuters parked near the Metro A Line station also call when a key goes missing. Wherever your Hyundai is, we come to you.
