What is the battery model for Audi car keys?

[OAiden]

Audi car keys for most models generally use CR2032 coin cell batteries. Typically, car keys use coin cell batteries, which have a relatively long lifespan. There are two main channels for replacing key batteries, primarily through authorized 4S dealerships where battery quality is comparatively better. Steps to replace the battery in an Audi car key: 1. First, remove the old battery by pressing the switch on the metal part of the key's back. While pressing the switch, pull out the metal part to reveal the hidden mechanical key. 2. 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; press them simultaneously and pull outward. 3. Once removed, you can proceed to replace the new battery, being careful not to reverse the positive and negative terminals. The installation steps follow the reverse order of the removal process.
