This guide will walk you through the easy steps to replace your 2007 Audi Key Fob Battery and get you back on the road with a key that works like new.
What You’ll Need to Replace Your Audi Key Fob Battery
Before you begin, gather these simple supplies. You likely have most of these items already at home. This task requires minimal tools and is designed for ease and convenience.
-
One CR2032 Battery: This is the standard button cell battery size for most Audi key fobs of this era, including models from 2007. You can find these batteries at most drugstores, supermarkets, or online retailers like Amazon. Buying a multi-pack can be economical if you have multiple keys or want to have spares on hand.
-
Small Flat-Head Screwdriver: Eyeglass repair screwdrivers are ideal due to their size, but any small flat-head screwdriver will work. Alternatively, a pen or similar thin, sturdy object can be used carefully if you don’t have a screwdriver readily available. The key is to use something that can gently press the release tabs without damaging the key fob casing.
Step-by-Step Guide to Replacing Your 2007 Audi Key Fob Battery
Follow these simple steps to replace your 2007 Audi key fob battery quickly and efficiently. The process is straightforward and requires no technical expertise.
Step 1: Accessing the Battery Compartment
Locate the two release tabs on your Audi key fob. The first tab is situated on the side of the key fob, near where the metal key blade folds into the plastic housing. The second tab is on the bottom of the key fob, opposite the key ring. Using your small flat-head screwdriver, gently but firmly press in the tab on the side of the key fob. You should hear a slight click or feel the back cover begin to loosen.
Next, while still applying slight pressure to the first tab, locate and press the second tab on the bottom of the key fob. Press this tab firmly to fully release the back cover. With both tabs pressed, the back cover should pop off easily. You can then remove the cover completely with your fingers.
Step 2: Replacing the Old Battery
With the back cover removed, you will see the CR2032 battery. Note the orientation of the battery before removing it; the positive (+) side should be facing upwards. Gently pry out the old battery. You can use your fingernail or the edge of the small screwdriver to carefully lift the battery out of its compartment. Dispose of the old battery responsibly according to local regulations.
Now, take your new CR2032 battery and insert it into the compartment, ensuring the positive (+) side is facing upwards, matching the orientation of the battery you just removed. Press down gently to snap the new battery into place.
Step 3: Reassembling the Key Fob
Once the new battery is securely in place, reattach the back cover of your Audi key fob. Simply align the cover with the base and press it firmly until it clicks back into place. You should hear a distinct click indicating that the cover is securely fastened. No tools are needed for reassembly; just press firmly with your fingers.
Step 4: Reprogramming Your 2007 Audi Key Fob (If Necessary)
In most cases, replacing the battery in your 2007 Audi key fob will not require reprogramming. However, if you find that your key fob is still not working after replacing the battery, or if the red indicator light on the fob doesn’t illuminate when you press a button, reprogramming might be necessary.
To reprogram your Audi key fob, insert the key into the ignition of your 2007 Audi. Turn the ignition to the “ON” position (just before starting the engine) and then back to the “OFF” position. Repeat this process five times in quick succession. This procedure should resynchronize your key fob with your vehicle.
Troubleshooting Your 2007 Audi Key Fob Battery Replacement
-
No Red Light: If you press the lock or unlock buttons on your key fob and do not see a red light indicator, double-check the battery installation. Ensure the CR2032 battery is correctly oriented with the positive side facing up. If the light still doesn’t appear, try a new CR2032 battery to rule out a dead battery. If problems persist, there might be an issue with the key fob itself, such as water damage or internal component failure, potentially requiring key fob replacement.
-
Red Light but No Door Response: If the red light illuminates when you press buttons, but your car doors do not lock or unlock, the key fob likely needs reprogramming. Follow the reprogramming steps outlined above for your 2007 Audi model. If reprogramming doesn’t work, consult your Audi owner’s manual or contact an Audi dealership for further assistance. There might be a different reprogramming procedure for specific 2007 Audi models or other underlying issues.
Replacing your 2007 Audi key fob battery is a straightforward DIY task that can save you significant expense. By following these simple steps, you can quickly restore your key fob’s functionality and avoid unnecessary dealership costs. Enjoy the convenience of a fully working key fob once again!
