Ever arrived at the beach ready to surf, only to worry about leaving your key fob in the water? Or stood at your NEXO’s door, pressing the fob with no response?

Extract the Mechanical Key

First, locate the release button on the bottom of your NEXO key fob. Press it firmly, then pull the mechanical key out. This key is small but sturdy—designed for emergency use.

Unlock the Door

Push the forward end of the driver’s door handle. The rear end will pop out. Grab it and pull toward you. Behind the rear end of the handle, you’ll see a small plug covering the mechanical lock. Use the tip of your mechanical key to lift this plug (don’t force it—gentle pressure works). Insert the key into the lock and turn it clockwise to unlock the door.

Lock the Door

To lock, insert the key into the lock and turn it counterclockwise. This works even if the fob is inside the car—perfect for when you want to leave the fob behind.

Leave the Fob Inside Safely

If you’re heading to the beach or a swim, follow these steps: Use the fob to lock all doors first. Then unlock the driver’s door with the mechanical key. Place the fob in a safe spot inside (like the center console). Re-lock the door with the mechanical key. You’re ready to go—no need to worry about losing your fob in the water.

  • Don’t force the plug: The lock plug is delicate. Use the key’s tip to lift it slowly to avoid breaking it.
  • Check the lock: After re-locking the door (when leaving the fob inside), give the handle a gentle tug to ensure it’s secure.
  • Keep the key clean: Dirt or sand can jam the mechanical key. Wipe it with a cloth after use, especially if you’ve been at the beach.
