Why Genuine Parts

The distinctiveness of a Mercedes-Benz vehicle begins with the quality of its parts and accessories. Every component is artfully designed, and promises superior performance, reliability, and longevity. Aftermarket parts won’t do your Mercedes-Benz justice; they simply aren’t strong enough to accommodate its advanced engine, transmission, brake system, etc. for long periods of time. That’s why we recommend nothing but OEM to our customers!

We make it easy for drivers in Eastvale, Chino, and beyond to find the right parts and accessories. Our parts center holds over 100,000 OEM parts! On the off chance we don’t have what you need, we’ll gladly order it for you. To request a specific item, simply complete our Mercedes parts ordering form online, or contact our parts department to speak with a friendly, knowledgeable Parts Advisor.

The best part? Each part in our inventory is backed by a Parts Limited Warranty, doubling the peace of mind you can only get from buying OEM. Don’t forget to check out our parts specials before submitting an order!

Replacement Keys

If you misplaced the key to your Mercedes-Benz, we’re just a short trip from Rancho Cucamonga and Fontana! For security purposes, only you or an authorized party can order a replacement key to your vehicle. To retrieve your new key, be sure to arrive at our dealership with proof of identity and ownership. We require the following documents:

If you are the original owner:

The current state registration for the vehicle.
A current driver’s license, identity card, or passport

If you are an authorized representative:

The current state registration for the vehicle.
A current driver’s license, identity card, or passport.
Signed and dated authorization from the vehicle’s owner.

Activating Your Key

After we receive the appropriate documentation, we’ll need to synchronize the new key with your car. We can’t program your new key remotely, whether you live nearby in Chino, or further away in San Bernardino. Programming a key fob requires that the vehicle be in same vicinity as the key fob.

*duplicated or photocopied documentation will not be accepted.
