The Mercedes-Benz E Class W210, 1995-2003, features a variety of impressive technologies, including “Touch Shift,” which improves gear changes, and a facelift, which has been praised by critics and owners alike. Like any new vehicle, though, the W210 eventually demonstrated a few common issues, such as ignition switch and remote key problems.
Some drivers have reported that they are unable to turn the key upon inserting it into the ignition, resulting in, of course, their car failing to start. Typically, the vehicle doesn’t sound, which indicates that the W210 isn’t even recognizing the key. Sometimes after removing and reinserting the key several times, the German auto will start. Oftentimes, the issue lies within the wires and/or coil embedded within the key. This coil communicates with the car battery, but it can become damaged if dropped. Alternately, the issue may be a malfunctioning EIS switch.
Some drivers disassemble the key in order to troubleshoot. They might find that the coil is broken. Alternately, cleaning the red lens might solve the problems. Other drivers carry two keys with them, the faulty key, as it will still unlock the doors, plus the other key, without the remote functions, to start the car. This, however, is no way to enjoy your German import.
For a cost effective solution, we recommend calling a nearby German auto technician because an independent specialist will be familiar with your E Class and its common issues. They won’t drain your pocketbook, yet they’ll have the proper tools and experience to accurately diagnose and remedy these malfunctions.
