Replacing the key fob for your 1999 Mercedes E320 can seem like a daunting task, but it doesn’t have to be. Whether you’ve lost your only key, need a spare, or your old one is simply worn out, this guide will walk you through the process, providing valuable insights and practical solutions.
Understanding Your 1999 Mercedes E320 Key Fob
Before we dive into the replacement process, let’s understand the key fob itself. The 1999 E320 uses a type of key fob known as a “flip key”, featuring an integrated metal key that flips out from the fob. This key fob communicates with your car’s immobilizer system using radio frequencies to allow the engine to start.
Common Reasons for Key Fob Replacement
Several issues might necessitate a key fob replacement:
- Lost or Stolen Key Fob: This is the most common reason. Losing your only key can be stressful, requiring a quick replacement.
- Damaged Key Fob: Wear and tear can take a toll on the buttons or the casing, affecting functionality.
- Malfunctioning Electronics: Internal electronic components can fail over time, making the key fob unresponsive.
1999 Mercedes E320 Key Fob Replacement Options
You essentially have three options for replacing your 1999 Mercedes E320 key fob:

What You Need to Program a 1999 Mercedes E320 Key Fob
If you’re technically inclined and want to attempt DIY programming, here’s what you’ll typically need:
- A Working Key Fob: You’ll need at least one working key to program a new one in most cases.
- New Uncut Key Fob: Purchase a blank key fob compatible with your car model.
- Programming Instructions: Search online forums or owner manuals for the specific steps.
Important Note: DIY programming is not always straightforward. Incorrect procedures can potentially disable your existing key fobs, leading to a bigger headache and more expense.
Choosing the Right Key Fob
When choosing a replacement key fob, ensure it matches the frequency and features of your original. The 1999 E320 uses an infrared (IR) system for keyless entry. Websites selling replacement fobs often provide compatibility information, but don’t hesitate to contact them for confirmation if you’re unsure.
Tips for Avoiding Key Fob Problems
- Regularly Inspect Your Key Fob: Check for physical damage, worn-out buttons, and replace the battery proactively.
- Keep Your Key Fob Dry: Moisture can damage the electronics inside the fob.
- Avoid Excessive Heat or Cold: Extreme temperatures can affect battery life and electronic components.
