How can I extend the range of my Audi A4's keyless entry system?

I often park my Audi A4 in a large lot and find that the keyless entry system doesn't always work from far away. What options do I have for extending the range of the keyless entry system?

You can try purchasing and installing a range extender specifically designed for your Audi A4 keyless entry system. This will boost the signal and allow you to unlock your car from a greater distance.

I had the same issue with my Audi A4 and found that keeping the key fob closer to my body, rather than in my pocket or purse, helped improve the signal range.
