Mercedes-Benz ignition switch (often referred as immobilizer module) can become faulty and in some cases due to user error. For example, some common reasons why the ignition module failed are:

  • Low battery voltage
  • Power surge due
  • Connecting jump starting cables while key is in the ignition.

During any of the above scenarios, the EIS-EZS may lose its memory. While it can be diagnosed with Start Diagnostic Scanner used at dealerships, it can’t be repaired with this scanner. Mercedes dealers don’t repairer a bad EIS-EZS module. They will recommend that the module be replaced. That’s not necessarily the only solution, see alternatives below.


We will repair your issue and mail out the ignition switch within 48-72 hours of receiving your
1) Ignition switch,
2) Existing keys for the ignition switch.

    Finally, a Solution That Works
    Size: 60 Count (Pack of 1)
    I was skeptical about probiotics for oral health, but this product proved me wrong. This oral probiotic targets the source of bad breath beautifully. My gums feel healthier, and my confidence is back. The lime flavor is refreshing without being overpowering. A must-try for anyone needing a reliable bad breath treatment for adults.

    Soothing, moisture-locking oral coat that eliminates morning dryness without burning your mouth
    Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
    Standard alcohol-based mouthwashes give a powerful blast of burning freshness, but they completely dry out your tissues and make a lack of natural saliva much worse. Biotene Dry Mouth Oral Rinse fixes this issue entirely by skipping the harsh astringents. It uses a specialized mouth-moisturizing system packed with hydrating humectants like glycerin, xylitol, and sorbitol. This combination creates a slippery, lubricating layer over your gums and cheeks that mimics your natural saliva to keep your mouth comfortable and damp. The daily utility of this formula is perfect if you struggle with persistent stickiness, difficulty swallowing dry foods, or a scratchy throat. It provides immediate relief that keeps working for up to four hours, soothing sensitive oral tissue and actively fighting the bacteria that cause chronic bad breath. The gentle, sugar-free fresh mint flavor leaves you feeling genuinely clean and maintains a healthy, balanced pH level in your mouth to protect your teeth from potential cavities. It is a fantastic, non-burning formula to use right before bed or throughout the day to completely wash away that uncomfortable, parched feeling and wake up with lasting comfort.
