How to Replace the Key Battery for an Audi Car?
2 Answers
Audi car key battery replacement steps are as follows: 1. Before replacing the key battery, it is necessary to first understand the battery model of the car key. Generally, you can check it in the vehicle user manual and select a new key battery according to the specified model. 2. Press the switch on the metal part of the key back. While pressing the switch, pull the metal part outward to remove the hidden mechanical key. 3. After removing the mechanical key, you can see the internal structure of the original metal part. There are two clips on both the front and back sides. Press them simultaneously and pull outward. 4. Once removed, you can replace the new battery. Be careful not to reverse the positive and negative poles. The installation steps are the reverse of the disassembly sequence.
Speaking of replacing the Audi key battery, I once almost broke the key while trying to do it myself before figuring out the trick. The key is to first confirm the key model. For the older version with physical buttons, there's a metal clasp about the size of a fingernail on the back cover. You need to gently press the gap with a small flat-head screwdriver until you hear a click, then you can open the back cover. The newer touch-sensitive keys are even trickier, requiring a plastic pry tool to slowly slide along the thin seam at the bottom. It's crucial to check the orientation of the CR2032 coin cell battery in the battery compartment—if installed backward, it won't work at all. When closing the cover, remember to press the edges first before the middle to avoid misaligning the waterproof seal. Oh, and if the remote range shortens after replacement, it might be due to oxidation on the battery contacts—just rub the copper pieces with an eraser.
