Where is the Mercedes key sensing area?

The Mercedes key sensing area is located on the car's center console. The sensing receiver of Mercedes cars is very sensitive. When the car key is in your pocket and within two meters of the car, the door can be easily opened without any operation. The signal receiver is located under the center console. When the remote key has sufficient battery, it works within a range of several meters. Relevant information about the car key's 'hold' button is as follows: 1. Introduction: Press and hold the 'hold' button for a few seconds to open the trunk, avoiding the danger of opening the trunk while the vehicle is in motion, hence the name 'hold'. 2. Other functions: The 'hold' button is not a trunk opening button but a remote engine start button. Within a remote distance, press and hold for 2 to 3 seconds, and the car will start automatically. This function allows you to adjust the interior temperature in advance during winter and summer.
Every time I drive my Mercedes into the garage, the key sensing area is in the small groove under the steering wheel. Just casually placing the key near it starts the car—super convenient. I remember when I first got the car, I kept trying near the cup holder, but the manual mentioned that most Mercedes models have it in this spot because it's easily accessible. If the car battery is low or there's signal interference, the sensing range shortens, so you'll need to get closer. It's also important to maintain the key battery to avoid awkward situations on the road. The location might vary slightly depending on the model or year—for example, older Mercedes CLS models have it near the center console cup holder—so it's best to familiarize yourself with the exact spot when picking up the car to save hassle.
Those who have driven a Mercedes-Benz know that the key sensing area is located in the driver's zone, particularly the sensing point below the left side of the steering wheel. Just place the key there, and the car starts effortlessly. From my own experience, this design helps prevent accidental operations by keeping the key close to the core control components. If the signal is weak or fails to detect, check if the key is obstructed by a metal case or debris. In daily use, keeping the key dry and charged ensures highly responsive sensing. Other brands may have different placements, but Mercedes-Benz's system is quite reliable—even occasional rainy days or high humidity inside the car have minimal impact.
