How can I program the keyless entry remote for my Audi A4?

I recently purchased a used Audi A4 and I'm having trouble programming the keyless entry remote. How can I do this myself without having to go to the dealership?

First, try replacing the battery in the remote. If that doesn't work, you can usually find instructions on how to program your specific model of Audi online. Alternatively, you could take it to an auto locksmith who may be able to program it for you at a lower cost than the dealership.
