Understanding the 1997 Mercedes Benz S500 Key Fob System
The 1997 S500 utilizes an infrared (IR) based key fob system. This means the fob transmits a coded signal to a receiver in the car, similar to how a TV remote works.

This system, while advanced for its time, can be susceptible to issues like weak batteries, faulty IR emitters, or receiver problems in the car. Knowing the signs of these problems can save you time and money.

-
Intermittent Key Fob Function: This often suggests a weak battery, a loose connection in the key fob, or interference from other electronic devices. Check and clean the battery contacts and ensure the key fob casing is secure.
