Step-by-Step Guide to Changing Your Audi Key Fob Battery
Let’s explore the battery replacement process for each type of Audi key fob. You’ll likely find your key fob style among these descriptions.
For Audi Remote Battery Fobs
This is a common style, often featuring a metal key that flips out. Here’s how to replace the battery:
-
Flip Out the Metal Key: Begin by extending the metal key blade, just as you would when using it to manually open your car door. This will give you access to the key fob casing.
-
Locate and Press the Black Cover Release: Look for a small black cover, usually near where the key blade is housed. You’ll need a small screwdriver or a similar thin tool to gently press this cover.
-
Pop Open the Back Cover: While pressing the black cover release, carefully use your fingers or the screwdriver to pop off the back cover of the key fob. It should detach relatively easily.
-
Remove the Back Cover and Find the Battery: Once the back cover is removed, you’ll see the battery compartment. The battery will be visible inside.
-
Take Out the Old Battery: Gently remove the old battery. Note the orientation of the battery – how the positive (+) and negative (-) sides are positioned. This is important for inserting the new battery correctly.
-
Insert the New CR2032 Battery: Take a new CR2032 battery (this is the standard battery for this type of Audi key fob). Insert it into the battery compartment, ensuring the polarity matches the orientation you noted earlier.
-
Reattach the Back Cover: Carefully snap the back cover back onto the key fob until it clicks securely into place.
For Audi Smart Keyless Entry Remote Battery Fobs
These key fobs are designed for keyless entry and push-button start. The battery replacement is slightly different:
-
Press and Hold the Key Release Button: On the chrome or metallic part of your smart key fob, you’ll find a small release button. Press and hold this button with your thumb.
-
Remove the Metal Key Blade: While holding the release button, gently pull out the metal key blade from the fob casing. This blade is for emergency access to your vehicle.
-
Detach the Battery Holder Cover: With the key blade removed, you’ll see a small plastic cover that houses the battery holder. Carefully detach or slide this cover off to expose the battery.
-
Remove the Old Battery: Take out the old battery, again noting its orientation in the holder.
-
Insert the New CR2032 Battery: Replace the old battery with a new CR2032 battery, making sure it’s inserted with the correct polarity.
-
Reattach the Battery Holder Cover: Place the battery holder cover back onto the fob and ensure it’s securely in place.
-
Reinsert the Metal Key Blade: Slide the metal key blade back into its slot until it clicks and locks into position.
For Audi Flip Key Battery Fobs
Flip keys are another style where the key blade flips out, but the casing and battery access are different:
-
Separate the Fob Case: Use a flathead screwdriver to gently pry open the key fob case. Insert the screwdriver into the seam running around the edge of the fob and carefully twist to separate the two halves of the case.
-
Set Aside the Key Blade Side: Once the case is split, set aside the half of the fob that contains the flip-out metal key. You’ll be working with the other half.
-
Open the Battery Shell: On the remaining half, use your screwdriver to further separate the shell, revealing the battery compartment.
-
Remove the Old Battery: Take out the old battery. In this type of fob, you’ll typically find a CR1620 battery. Note the battery’s orientation.
-
Insert the New CR1620 Battery: Insert a new CR1620 battery into the compartment, ensuring correct polarity.
-
Snap the Shell Closed: Press the battery shell back together until you hear a click or snap, indicating it’s securely closed.
-
Reassemble the Fob: Bring the two halves of the key fob case back together and press them firmly until they snap back into their original position, reassembling the entire key fob.
Tips for a Smooth Audi Key Fob Battery Change
- Battery Type is Key: Always use the correct battery type. CR2032 is common for many Audi fobs, but flip keys often use CR1620. Check your old battery before purchasing a replacement if you’re unsure.
- Gentle is Best: When opening your key fob, be gentle to avoid damaging the casing or internal components.
- Polarity Matters: Pay close attention to the battery’s orientation when removing the old one, and ensure the new battery is inserted the same way.
- Having Trouble? If you encounter difficulty or prefer professional assistance, don’t hesitate to schedule service with your local Audi dealership or a trusted automotive service center.
