As an Audi owner, you appreciate the blend of luxury and technology your vehicle offers, and your key fob is a crucial part of that experience. From remote locking and unlocking to starting your engine, the key fob provides seamless convenience. However, like any electronic device, the battery in your Audi key fob will eventually need replacing. Knowing the correct Audi Key Fob Battery Type and how to replace it is essential for maintaining the functionality you rely on.
This guide, brought to you by the experts at keyfobprog.com, will walk you through everything you need to know about your Audi key fob battery. We’ll cover identifying your key fob type, determining the correct battery, step-by-step replacement instructions, and even what to do if you need to reprogram your fob. Let’s ensure your Audi key fob is always ready to keep you connected to your vehicle.
Identifying Your Audi Key Fob Battery Type
The audi key fob battery type isn’t universal across all models and years. Audi uses a few different key fob designs, and each may require a specific battery. The most common types you’ll encounter are the CR1620 and CR2032 batteries. Let’s break down the key fob styles to help you identify which battery type is likely used in yours.
Audi Flip Key Fob Battery Type: CR1620
If your Audi key fob features a physical metal key that flips out from the fob body, you likely have the flip key fob. The audi key fob battery type for this style is typically the CR1620. This is a 3V lithium coin cell battery that provides reliable power in a compact size.

Audi Smart Keyless Entry Remote Battery Type: CR2032
For Audi models equipped with smart keyless entry, the key fob is usually a bit different. These “smart” fobs often have a more oblong or rectangular shape and don’t necessarily have a flip-out key, although they may include a removable emergency key. The standard audi key fob battery type for these smart keyless entry remotes is the CR2032. This is also a 3V lithium coin cell battery, but it’s slightly larger and often offers a longer lifespan than the CR1620.

Audi Remote Battery Type (Older Models): CR2032
Some older Audi remote fobs, even those without keyless entry, might also use the CR2032 battery. The best way to confirm your audi key fob battery type is to open your specific fob and visually check the existing battery before purchasing a replacement.

Step-by-Step Guide to Audi Key Fob Battery Replacement
Once you’ve identified your audi key fob battery type, replacing it is a straightforward process you can do at home. Follow these steps based on your key fob style:
Replacing the Battery in an Audi Flip Key Fob (CR1620)
- Prepare Your Tools: You’ll need a small flat-head screwdriver and a new CR1620 battery.
- Open the Fob: Gently insert the flat screwdriver into the seam of the key fob casing. Carefully twist to separate the two halves of the case.
- Separate the Halves: Set aside the half containing the flip metal key. Focus on the other half where the battery is located.
- Access the Battery: Use the screwdriver again to gently separate the remaining half further, exposing the battery compartment.
- Remove the Old Battery: Carefully remove the CR1620 battery. Note the orientation (+ and – sides) for correct installation of the new battery.
- Install the New Battery: Place the new CR1620 battery into the compartment, ensuring the positive (+) and negative (-) sides are oriented correctly as you noted.
- Reassemble the Fob: Snap the two halves of the fob casing back together until they are securely closed.
- Test: Test the key fob to ensure it’s working correctly. If your car doesn’t immediately recognize the fob, refer to the note below regarding key insertion into the door.
Note: If your Audi doesn’t recognize your key fob after battery replacement, insert the physical key into the driver’s side door. Manually unlock and then lock the door. Remove the key and press the “unlock” button on the fob. This can sometimes help resynchronize the key fob with your vehicle.
Replacing the Battery in an Audi Smart Keyless Entry Remote (CR2032)
- Prepare Your Battery: You’ll need a new CR2032 battery.
- Remove the Emergency Key: Locate the key release button (usually a small chrome button) on the fob. Press and hold it while pulling out the metal emergency key.
- Access the Battery Holder: With the emergency key removed, you’ll see an exposed plastic battery holder. Grip this holder with your thumb and carefully pull it out from the key fob.
- Remove the Old Battery: Take out the old CR2032 battery, again noting the positive and negative side orientation.
- Install the New Battery: Insert the new CR2032 battery into the holder, ensuring correct polarity.
- Reinsert Battery Holder: Slide the battery holder back into the key fob until it clicks into place.
- Reinsert Emergency Key: Slide the metal emergency key back into the fob until it locks securely.
- Test: Test the key fob functions.
Replacing the Battery in an Older Audi Remote (CR2032)
- Open the Metal Key (if applicable): If your older fob has a metal key, flip it open.
- Locate the Back Cover: Look for a small indentation or seam on the back cover of the key fob.
- Pry Open the Cover: Use a small screwdriver to gently press into the indentation or seam and pop open the back cover.
- Remove the Back Cover: Carefully remove the back cover to access the battery compartment.
- Remove the Old Battery: Take out the CR2032 battery, noting its orientation.
- Install the New Battery: Place the new CR2032 battery in the correct position.
- Reattach the Cover: Snap the back cover back onto the key fob until it’s securely closed.
- Test: Test the key fob.
When to Consider Audi Key Fob Programming
In most cases, replacing your audi key fob battery type will not require reprogramming your key fob. However, if you experience issues after battery replacement, or if you have a brand new key fob, programming might be necessary.
For simple resynchronization after battery changes, the door lock method described above often works. However, for new key fobs or more complex issues, Audi key fob programming can be more involved and may require specialized equipment.
While basic programming steps exist for existing remotes (as outlined in the original article you provided), programming a brand-new key fob or dealing with multiple fobs is best handled by professionals.
