Is your Audi TT key fob becoming unresponsive? You might be facing the common issue of a dead battery. The key fob for your Audi TT MK3 uses a small, non-rechargeable lithium-ion battery to power its keyless entry system. This system is essential for remotely locking and unlocking your vehicle, and in some Audi TT models, it even controls features like windows and wing mirrors. When this battery runs out, your key fob will stop working, requiring a battery replacement. Fortunately, changing the battery in your Audi TT key fob is a straightforward process you can easily do yourself at home.
Follow these simple steps to replace the battery and restore full functionality to your key fob:
Step 1: Locate and Press the Key Release Buttons
To begin, you’ll need to release the physical key from the key fob casing. On the bottom of your Audi TT key fob, you will find two small black buttons located on either side. Simultaneously press and hold these two buttons.
Step 2: Slide Out the Physical Key
While keeping the black buttons pressed, gently slide the physical key out from the key fob. This key is a backup entry method and needs to be removed to access the battery compartment.
Step 3: Open the Key Fob Casing
With the physical key removed, you will now see two small black tabs inside the key fob casing. These tabs secure the battery compartment. Pinch these two black tabs together and carefully pull the casing apart. This action will reveal the battery inside.
Step 4: Replace the Old Battery with a New CR2032
The Audi TT key fob uses a CR2032 type battery. Carefully remove the old CR2032 battery from its holder. Take your new CR2032 battery and insert it into the holder, ensuring the positive (+) side is facing upwards. It is crucial to use the correct CR2032 battery type to ensure proper function of your key fob. You can easily find CR2032 batteries at most drugstores, supermarkets, and online retailers.
Step 5: Reassemble and Test Your Key Fob
Once the new battery is in place, carefully reassemble the key fob casing by reversing the steps you took to open it. Slide the two halves back together until they click securely. Finally, slide the physical key back into the key fob until it clicks into its locked position. Test your key fob to ensure the new battery is working correctly by attempting to lock and unlock your Audi TT remotely.
Battery Disposal
Remember to dispose of your old non-rechargeable coin cell battery responsibly. Many stores that sell batteries will also take old batteries for recycling. Alternatively, you can take your used battery to a local recycling facility for safe disposal.
By following these simple steps, you can easily change the battery in your Audi TT key fob and avoid a potentially inconvenient situation. Enjoy the continued convenience of your keyless entry system!
