Audi A3 Key System Overview

The Audi A3 (2015-2026) uses a proximity-based smart key system with push-button start. The key fob communicates wirelessly with the vehicle, allowing you to unlock the doors by touching the handle and start the engine without inserting a key. This model supports Smart Key, Key Fob, Switchblade Key. Some model years feature a switchblade-style flip key where the metal blade folds into the fob body for a compact, pocket-friendly design. We handle the whole thing on-site. Cut the key or fob, program it to your Audi A3, test every function, you drive away.
