Since your Audi Q7's keyless entry was previously functioning, it's safe to assume that the issue does not stem from incorrect key programming. In most cases, a key fob stops working suddenly due to a depleted battery. A CR2032 "watch battery," which costs around $3-$5, can usually resolve this issue and can be purchased at stores like Walmart. If the key fob experiences more complex problems, such as a cracked internal PCB from wear and tear, it may necessitate further troubleshooting. However, the most common culprit is typically just the battery.
Certain issues with the keyless remote of the Audi Q7 include a weak battery, a malfunctioning key transponder, and a faulty actuator.
