Prerequisites and Tools Required

Before replacing your Tiguan key battery, gather the following items:

• CR2032 battery – the standard Volkswagen key battery type.
• Small flathead screwdriver or plastic pry tool – used to open the key fob housing.
• Clean workspace – working on a cloth or towel prevents small components from rolling away.

That's it. No diagnostic tools or dealership visit required.

Step 1: Removing the Emergency Key

Locate the small release button on the back or side of your key fob. Press and hold the button while gently pulling the metal emergency key out of the fob.

Step 2: Opening the Key Fob

Look for the seam where the two halves of the key fob meet. Insert the tip of your flathead screwdriver into the seam and twist gently. Apply steady pressure rather than forcing the case open.

When done correctly, the fob will pop open easily. Inside you'll see the round battery and circuit board.

Step 3: Replacing the Battery

Remove the old battery using your fingernail or a small tool. Note the battery orientation before removing it.

Insert the new CR2032 battery VW key fob with the positive side facing upward. Press gently until the battery sits flat inside the compartment.
