Note that crack in the fob on the logo side. Make sure the key is folded. Firmly grasp each side of the crack and pull so that it will pull into two pieces. The battery is in the piece with the buttons on it. On the side opposite of the buttons, detach the cover holding the battery. This should be the side with the VW part number. Replace the battery and assemble the key back together.
Open the keyless remote and you will see the battery take it out and replace it with the same size.
how do you change the battery in a 2002 jetta keyless entry pad?
it seems you cant , seald unit
Insert something thin and hard, such as a pocket knife blade, in between the remote halves. After this, simply pull the halves apart and replace the old battery with the new. Snap the remote back together.
Most keyless remotes just snap together. Look closely for a small notch in the seam of the remote. A regular watch style battery is inside.
Take a small common screw driver and twist it in the seam.
You open the remote with a coin or small screwdriver, and pop the battery out. My 4Runner uses a CR2016 battery, which you can pick up at Walmart or any hardware store. Put the battery in with the + sign facing south, and you should be all set.
It is no BIG deal. All you have to do is rewire the whole thing. Follow the instructions in the owners manual for resetting the remote. The remote entry transmitter in GM vehicles must be reset when you replace the battery. Usually that consists of standing near the vehicle and holding the remote entry for about 10 to 15 seconds, but refer to the owners manual to make sure.

I had a 1998 Jetta, but I don't remember if they had remote entry. If it does, buy a remote entry blank off of ebay. Then, go to the dealer with the VIN and proof of ownership and have them cut and program the key. If it doesn't have remote entry, just talk to a dealer. Like you said, your son has the "Valet" or "Sub Master" key. Take it to a Locksmith and he/she can cut your son a new master. Ilco blank# X203
