What is the maximum distance for locking a Mercedes-Benz with the remote key?

[StAubrey]

Mercedes-Benz remote keys can generally achieve a range of approximately 30 to 50 meters under new car conditions. Factors affecting the remote key's range: The effective distance of a car remote key depends not only on the transmitter, key battery level, and car receiving antenna but also on obstacles around the vehicle such as trees and walls. Additionally, interference from other signals, such as mobile phone signals, signals from other car keys being used simultaneously, and surrounding WiFi signals, can also impact the range. Solutions for shortened remote key range: Therefore, if you suddenly notice that your car's remote key range has significantly decreased, there's no need to worry excessively. Try testing it in a different location. There have been instances where owners experienced remote key malfunctions, only to discover that interference from their mobile phone signals was the cause.
