What Is Mercedes-Benz KEYLESS GO® and KEYLESS START®?

When you bring a new Mercedes-Benz home to San Jose, you can leave the experience of fumbling with your keys in the rearview. Luxury features like Mercedes-Benz KEYLESS GO® and Mercedes-Benz KEYLESS-START® make it easier to get in and get going on your way to Bay Area, with the ability to unlock, lock, start, and stop your vehicle when your keys are still in your bag or pocket. Most new models in the inventory at Fletcher Jones Motorcars of Fremont are equipped with either KEYLESS GO® or KEYLESS-START® as standard, and select models have both. Read our guide below to learn more about the capabilities these features will add to your daily life!

Mercedes-Benz KEYLESS-START®

With KEYLESS-START®, you can step on the brake and press the Engine Start/Stop button on the dashboard to start your car—no key required. This feature comes standard across the Mercedes-Benz lineup.

Each press of the Engine Start/Stop button is like turning the key one position in an ignition, as long as you don’t press on the brake while doing so. With one touch, you can turn on your vehicle’s accessories such as the radio. Press the button a second time and the dash lights and all electrical items will turn on. Press a third time with your foot off the brake, and everything turns off. You can also turn all features off by opening your door.

Mercedes-Benz KEYLESS GO®

This feature is essentially an upgrade of KEYLESS-START®. Like KEYLESS-START®, you can start the engine by pressing the brake pedal and dash-mounted button. However, Mercedes-Benz KEYLESS GO® takes the convenience one step further with the ability to unlock/lock your doors with only a touch of the door handle — you just need to ensure your key is somewhere in your pocket or bag. Mercedes-Benz KEYLESS GO® is standard on some of our most exclusive models, like the S-Class, but it’s available to add as an upgrade to almost any model you want!

How Does Mercedes-Benz KEYLESS GO® Work?

With Mercedes-Benz KEYLESS GO®, you can unlock, lock, start and stop your car or even close your windows and sunroof from outside your vehicle in San Francisco, simply by having your Smart Key in the immediate vicinity of your Mercedes-Benz.

• How to Unlock Your Doors with KEYLESS GO®: To unlock your car, firmly grip the driver’s door handle. To unlock all doors, grab any of the passenger handles.
• How to Start Your Car with KEYLESS GO®: To turn the engine on, simply step on the brake and push the Start/Stop button. To turn the engine off, put the car in park, leave your foot on the brake, and press the Start/Stop button once again. 
• How to Lock Your Doors with KEYLESS GO®: If you want to lock your vehicle from the outside, simply touch the sensor located on the door handle. Forgot to close the windows and sunroof? No problem. Keep your finger on the sensor until the windows finish closing.
