An Overview of Keyless Entry Systems
Mercedes-Benz vehicles typically employ one of two keyless entry systems:
- Passive Entry Go: This system detects the presence of a key fob within close proximity, unlocking the doors as you approach.
- Comfort Access: An enhanced version of Passive Entry Go, Comfort Access enables hands-free operation, allowing you to unlock the doors and start the engine without ever removing the key from your pocket.
Understanding your vehicle’s specific keyless entry system is essential, as it will guide the method you choose to bypass the missing key fob.
Method 1: Utilizing the Mechanical Key
Most Mercedes models still come equipped with a traditional mechanical key located within the key fob. If you have access to this key, the solution is straightforward:
- Locate the small release button on the key fob and press it.
- The mechanical key will slide out, allowing you to insert it into the keyhole behind the door handle and unlock the vehicle manually.
Method 2: Mercedes me Connect App (Subscription Required)
If you have a compatible Mercedes-Benz model and an active Mercedes me Connect subscription, you can use their smartphone app as a digital key:
- Download the Mercedes me Connect app and ensure your vehicle is linked.
- With your smartphone in hand, approach your Mercedes.
- The app will automatically detect your vehicle and allow you to unlock the doors and start the engine via your smartphone’s Bluetooth connection.

If you find yourself completely without a key and have no access to the mechanical key, there is still hope:
- Look for a small, rubberized panel near the trunk latch.
- Remove the panel to reveal the emergency battery access point.
- Connect a jumper battery to the terminals beneath the cover for 10-15 minutes, providing enough power to unlock the doors via the keyhole.
