Mercedes-Benz keys are high-security and tied to the car's electronics, so a hardware-store copy will not work. Whether you drive a C-Class or an E-Class, a replacement has to be matched to your specific vehicle and programmed so the car recognizes it. That is why we work from the VIN rather than guessing at the key type.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no shop to tow your Mercedes to. Whether you are in a driveway in Pathfinder, a parking lot near Diamond Hills Plaza or the roadside, our technician brings the equipment to you and does the work on site.

How it works in Diamond Bar

  1. 1

    Call and share your VIN

    Call (323) 997-8867 and tell us the make, model, year and your VIN. The VIN lets us confirm the correct key for your Mercedes-Benz before we head out.

  2. 2

    We come to your vehicle

    Our mobile technician travels to your car in Diamond Bar, at home, work or the roadside. We verify you are the owner and check the vehicle first.

  3. 3

    Key cut and programmed on location

    We prepare the replacement key and program it to your car on site. This covers lost keys, adding a spare, and all-keys-lost situations where no working key remains.

  4. 4

    Test everything before we leave

    We test the new key for starting, locking and unlocking, and confirm any remaining keys still work as expected, so you leave with a key you can trust.

We serve ZIP codes 91765 and 91789, including the gated Country Estates, Pathfinder, and the Sunset Crossing and Summitridge areas. If your key goes missing after a round at Diamond Bar Golf Course, we meet you at the car.

We also come to parking lots at Diamond Hills Plaza, Diamond Bar Center and Sycamore Canyon Park. Because we are fully mobile, you never need to move a car that will not start. Call (323) 997-8867 any hour and we will head to your Mercedes-Benz.

Mercedes-Benz keys in Diamond Bar — FAQs

What if I lost all my Mercedes-Benz keys in Diamond Bar?
An all-keys-lost situation can still be solved on site. Call (323) 997-8867 with your VIN and we will come to your C-Class or E-Class and make a new key.
Can you make a spare Mercedes key?
Yes. Having a spare made is usually easier and less stressful than replacing keys after losing every one. We do it at your location.
What if I have no original key?
We can still help. Proof of ownership and your VIN let us determine the correct key and program it to your car without an original.
Is a push-button key different from a bladed key?
Yes. Push-button smart keys and bladed keys work differently, and the right type depends on your model and year. We confirm it from your VIN before starting.
How do you confirm the right key for my car?
We use your VIN along with the model and year to identify the correct key for your Mercedes-Benz, so we do not rely on guesswork.
Do I have to bring my car to a shop?
No. We are fully mobile and come to you in Diamond Bar. Call (323) 997-8867 anytime, day or night.
