How can I extend the wireless range of my Audi A6's remote key?

I've noticed that the remote key for my Audi A6 doesn't work from a long distance. Is there a way to increase the wireless range of the key?

The best way to extend the range of your Audi A6's remote key is to upgrade to a newer model key, specifically the Frequency Hopping version rather than the older Fixed Code version. Along with longer range, the newer version offers better security and functionality.

Another option is to use a range extender or signal booster for your Audi A6's remote key. These devices can be easily installed in your car and will amplify the signal from the remote key, allowing you to unlock/lock your car from a greater distance.
