Radio Frequency (RF) and Infrared (IR)
Older Mercedes-Benz models mostly used a combination of Infrared (IR) signals for beginning the car (through the ignition slot) and Radio Frequency (RF) for locking and opening the doors. These signals are short-range and one-directional in most cases.
Ultra-Wideband (UWB) Technology
In newer models, Mercedes-Benz has introduced Ultra-Wideband (UWB) technology. This is a considerable security upgrade developed to avoid “relay attacks”-- an approach where burglars intercept the signal from a key inside a house to open a car on the driveway. UWB permits the car to calculate the exact range in between the key and the automobile by determining the time it takes for thoughts to get better and forth. If the key is not within a specific radius, the car will not begin.

This guarantees that if someone finds the key, they can not utilize it to take the vehicle.Order a Replacement: New secrets are often ordered from a central Mercedes-Benz center (such as the one in Texas for United States owners) and shipped to the dealer for last synchronization.Estimated Replacement Costs
