How do I enable keyless entry on my Audi A4?

I recently purchased a used Audi A4 and I noticed it does not have keyless entry. Is there a way to enable this feature without having to replace the entire key fob? Any recommendations on the best way to go about this?

You can enable keyless entry on your Audi A4 by purchasing a new key fob and programming it to your car. You can find instructions on how to program the key fob online or in your owner's manual. Alternatively, you can visit a certified Audi dealership and have them do it for you.

I had the same issue with my Audi A4. I found that buying a keyless entry kit from a third-party manufacturer and installing it myself was a more cost-effective option. However, if you are not confident in your ability to install it correctly, it's best to go to a dealership.
