As a proud owner of a 2011 Audi A4, you appreciate the blend of luxury and technology that comes with your vehicle. One of the convenient features you rely on daily is your key fob, offering keyless entry, remote start capabilities (if equipped), and more. However, like any electronic device, your Audi A4 key fob may require attention over time, particularly when it comes to battery replacement and reprogramming. Understanding how to handle these situations is crucial for maintaining seamless access and control over your vehicle.
While for complex issues or new key fob programming, scheduling a visit to an authorized Audi service center like Audi Hampton is always recommended, there are basic maintenance and reprogramming steps you can undertake yourself, especially when you’re in a pinch. This guide will walk you through the essentials of 2011 Audi A4 key fob battery replacement and provide a basic programming procedure for your existing remote.
Step-by-Step Guide to 2011 Audi A4 Key Fob Battery Replacement
Before diving into programming, let’s address the most common issue: a dead key fob battery. Replacing the battery in your 2011 Audi A4 key fob is a straightforward process. The type of key fob you have will determine the exact steps, but generally, for a 2011 Audi A4, you’ll likely encounter one of two main types: the flip key fob or the smart keyless entry remote.
Replacing the Battery in a 2011 Audi A4 Flip Key Fob
If your 2011 Audi A4 uses a flip key fob, battery replacement is quite simple. You’ll need a CR1620 battery, readily available at most battery retailers or our parts center. Follow these steps:
- Open the Fob: Locate the small notch on the side of your key fob. Gently insert a flat-head screwdriver into this notch to carefully pry open the case.

-
Separate the Case: Once you’ve started to open the case, carefully separate the two halves. Be mindful of the side with the flip metal key and set it aside.
-
Access the Battery: Further separate the remaining half of the fob using the screwdriver if needed. You will now see the battery compartment.
-
Remove and Replace Battery: Carefully remove the old CR1620 battery, noting the orientation of the positive (+) and negative (-) sides. Install the new CR1620 battery in the same orientation.
-
Reassemble the Fob: Press the two halves of the fob case back together until they snap securely closed. Ensure all parts are firmly rejoined.
Note: In some instances, after a battery replacement, your 2011 Audi A4 might not immediately recognize the key fob. If this happens, try manually unlocking and locking your driver’s side door using the physical key. Subsequently, remove the key and press the “unlock” button on the fob. This can often resynchronize the key fob with your vehicle.
Replacing the Battery in a 2011 Audi A4 Smart Keyless Entry Remote
For 2011 Audi A4 models equipped with a smart keyless entry remote, the battery replacement process is slightly different and requires a CR2032 battery. Here’s how to do it:
- Remove the Emergency Key: Find the key release button, typically a small button or latch on the chrome end of the fob. Press and hold this button to detach and remove the metal emergency key from the fob.

-
Access the Battery Holder: With the emergency key removed, you’ll see exposed plastic where the key was housed. Grip this plastic battery holder with your thumb and carefully pull it out from the key fob.
-
Battery Swap: Remove the old CR2032 battery from the holder, paying attention to the positive and negative side orientation. Insert the new CR2032 battery in the correct orientation.
-
Reassemble: Slide the battery holder back into the key fob shell until it clicks into place. Finally, reinsert the metal emergency key back into the fob.

Basic 2011 Audi A4 Key Fob Programming Procedure
After replacing your key fob battery, or if your existing 2011 Audi A4 key fob has lost synchronization, you might need to perform a basic reprogramming procedure. This method is for resynchronizing an existing remote, not for programming a brand new or additional key fob.
-
Manual Unlock and Ignition: Manually insert your 2011 Audi A4 key into the driver’s side door lock and unlock the car.
-
Press and Hold “Unlock”: On your key fob, press and hold the “unlock” button.
-
Ignition ON: While continuously holding the “unlock” button, insert the key into the ignition switch.
-
Turn to “ON” Position: Keep holding the “unlock” button and turn the ignition key to the “ON” position (just before starting the engine) for approximately two seconds.
-
Turn “OFF” and Remove Key: Turn the ignition key back to the “OFF” position and remove it from the ignition. Release the “unlock” button.
This procedure should, in many cases, resynchronize your existing 2011 Audi A4 key fob with your vehicle. Test the key fob functions to ensure it’s working correctly.
