How to Replace the Porsche Taycan Key Battery

The Porsche Taycan is a marvel of automotive engineering, representing the perfect blend of luxury, performance, and cutting-edge technology. One of its key components is the smart key, which allows for convenient access and operation of the vehicle. However, like any electronic device, the smart key’s battery will eventually need replacement to maintain its functionality. In this article, we will walk you through a simple and hassle-free process of how to replace the Porsche Taycan key battery.

Before We Begin

According to how to replace the Porsche Taycan Key battery article, before attempting to replace the battery in your Porsche Taycan key, it’s essential to gather the necessary tools and materials. You’ll need a new compatible battery for your key fob, typically a CR2032 lithium coin cell battery, which can be easily found in most electronics or hardware stores. Additionally, a small flathead screwdriver or a plastic opening tool will come in handy for opening the key fob without causing any damage.

Step 1: Identify the Key Fob Type

The Porsche Taycan key fob has seen some variations over the years. Before proceeding, identify the type of key fob you own. Older models may have a traditional key design, while newer models are equipped with a sleeker and more compact design. Each type might have a slightly different battery replacement process.

Step 2: Identify the Battery Compartment

Hold the key fob with the Porsche logo facing up and the buttons facing you. On the backside, you will notice a small compartment with a groove or notch. This compartment houses the battery and can be accessed for replacement.

Step 3: Remove the Old Battery

Using the small Phillips-head screwdriver, gently insert it into the groove or notch on the battery compartment cover. Apply slight pressure and carefully pry open the cover. Be cautious not to use excessive force to avoid damaging the key fob.

Once the cover is open, you will find the old battery (CR2032) securely placed inside. Take note of the battery’s orientation (positive and negative sides) before removing it. Use the screwdriver or a non-metallic tool to carefully pop out the old battery from its holder.

Step 4: Insert the New Battery

According to this how to replace the Porsche Taycan Key battery article, With the old battery removed, take the new CR2032 battery and ensure it is correctly oriented according to the markings inside the key fob’s battery holder. Gently place the new battery into the designated slot, ensuring a snug fit.

Step 5: Close the Battery Compartment

After inserting the new battery, align the cover back over the battery compartment. Press down gently until you hear a click, indicating that the cover is securely in place.

Step 6: Test the Key Fob

Once you have successfully replaced the battery and secured the cover, it’s time to test the key fob. Stand close to your Porsche Taycan and press the buttons on the key to verify if the battery replacement was successful. The key should function flawlessly, allowing you to lock, unlock, and start your vehicle without any issues.

Step 7: Dispose of the Old Battery Responsibly

Properly dispose of the old battery in an environmentally friendly manner. You can take it to a local recycling center or follow any regulations and guidelines for battery disposal in your area.

What Kind of Batteries Are Required?

Key fobs for Porsches and many other automobiles are typically powered by a circular, flat 3V battery. These are widely accessible in the Manhattan region — and nearly everywhere else – in drugstores, hardware stores, electronics stores, and so on. These batteries are also likely to be available from your local Porsche shop.

Battery Replacement:
(These instructions are fairly generic; however, more instructions are accessible on YouTube and other websites.)

  • Locate the metal key release button. Got it? It should now be pressed and slid. The key can now be removed.
  • The key fob must be wrenched open with a small flathead screwdriver or comparable item/tool.
  • To keep your key fob together, push your thumb down right above the battery (to prevent external buttons and contents from coming out).
  • The dead battery can now be removed. Take note of where the negative and positive sides are located so that you can properly install the new battery. Avoid touching the new battery terminals. Corrosion can be caused (in the long run) by your skin oil. That drains the life out of your fresh battery.
  • You should be in the same position as the battery.
