  • Mercedes key fob replacement - on-site, no need to tow
  • Key fob programming for all Mercedes-Benz models

Real Story: The "Lost Key at the Airport" Nightmare

A Mercedes S-Class owner in Atlanta returned from a business trip only to realize his key was missing from his carry-on. The dealership told him he'd have to tow his car and wait 10 days for a new key.

Instead, he called us. Within an hour, he had a brand-new key fob programmed, and he was on his way home.

Mercedes Key Fob Battery Replacement - The Simple Fix That Can Save Your Day

If your Mercedes key fob suddenly stops unlocking your car, struggles to start the engine, or only works when held inches from the door, chances are your battery is running low.

  • Quick Mercedes key fob battery replacements
  • Battery testing to rule out deeper issues
  • On-the-spot key fob reprogramming if needed

How to Change the Battery in a Mercedes Key Fob

  1. Press the release button and remove the emergency key.
  2. Use a small screwdriver to carefully open the fob.
  3. Replace the old battery - most Mercedes-Benz fobs use a CR2025 or CR2032 battery.
  4. Snap everything back together and test it.

If your key fob still isn't working after a battery swap, it may need reprogramming - we can handle that for you.

How to Open a Mercedes Key Fob - Step-by-Step Guide

Sometimes you need to open your Mercedes key fob to replace the battery or check for damage.

  1. Press the small release button on the back of the key fob to remove the mechanical key.
  2. Look for a small slot where the key was removed.
  3. Insert a flathead screwdriver into the slot and gently twist to separate the key fob casing.
  4. Once open, replace the battery or inspect for any internal damage.

Not comfortable doing this yourself? We can open it for you and swap the battery in minutes.

Mercedes vehicles are designed with advanced security features, which is great - until you accidentally lock your key inside or your fob malfunctions at the worst possible time.

  • Fast, damage-free lockout service for all Mercedes models
  • Trunk unlocking when the key is stuck inside

Real Story: The "Hotel Parking Lot Lockout"

A Mercedes GLE owner in Houston stepped out of his car to check into a hotel. The doors auto-locked while the key was still inside.

Instead of waiting hours for roadside assistance, he called us. Within 20 minutes, his car was unlocked - no damage, no waiting.

How to Remote Start a Mercedes with the Key Fob

Some Mercedes models come with remote start functionality, but many owners don't realize how to use it.

How to Remote Start Your Mercedes

  1. Press the lock button on your key fob.
  2. Immediately press the remote start button and hold for a few seconds.
  3. Your Mercedes should start, and the climate control will activate.

If your remote start isn't working:

  • Check that your key fob battery is fresh.
  • Ensure all doors are completely closed.
  • If issues persist, we can troubleshoot or reprogram your key fob.
