You can use the two keys to reprogram the car remote of 2000 VW Jetta.
"It all depends on the year that you wish to purchase. Some of the older Jetta's can be pretty inexpensive, while newer years are going to be much more. These cars usually hold their value and their replacement parts can get quite expensive since it is a foreign car."
Yes
With a VAG-COM, or get the dealer to do it.
If you can't find programming instructions you can get a programming guide from iKeyless.com

I just bought a replacement remote at www.keylessride.com . It was $45 plus tax and came with free programming instructions. The dealership was going to charge me $80 to program. My 16 yr old son and I programmed it in less than a minute. Matching instructions for the Clarion remote 93-99. Using 2 keys, put one key in the ignition, turn the igniton on, do not start the car. Close the door, put the 2nd key in the door lock, turn the key to the unlock position and hold it until you hear the alarm horn chirp, release the key. Press any button on the remote, you should hear a chirp from the alarm horn, press button on the 2nd remote, you will hear two chirps, 3rd remote will chirp 3 times, and the 4th remote will chirp 4 times, then lock the door with the key. Unlock the door, remove the key from the ignition, close the door and try the remote. You can match any remote to any car. You teach the car to respond to each remote. www.watercooledkey.com
