Question about 2004 Volkswagen Jetta
It was working fine and today after driving it I went to lock it and the remote would not lock the car unless i was standing right next to the driver door. I replaced the battery and the problem is still there.

No problem. The key fob is two pieces. The key part and the remote. Open the key as you would to sue it. Where the key flips open you can see a small recess about where the line of the trunck switch. This is where the key separates. You can pull it off or pry it with a small screwdriver. Once separated with remote part in your hand this also splits in 2. In the same area you split the key off insert the screwdriver in this recess and the fob will open giving you access to the battery. Also can be done by hand. It is a little tight so you will have to force which is normal. No screws just clipped. Make sure the battery is positioned in the right way and that you have 3 volts when you test the battery. 2.7 volts will make the remote not work or act funny.

one is located over the battery, the other is located in the side of the dash.
If you pop your hood the battery will be on your right sid in the front of the engine bay. There is a small rectangular piece on top of the battery with a lot of heavy guage red wires going to it. That is the engine bay fuse box.
if you open your driver side car door it's under neath a panel located inbetween the door and the dash board.

I hope this might help. -- I had the same problem yesterday and fix the problem today. The steps on the manual (page 32) was too simple and wrong for my case. Read carefully the followint steps and thank me if these steps work. -- JB (owner of Jetta 2.5, 2006 model)
* The most important thing is to make sure that the LED in the driver side window frame stays blinking. The blinking means that the receiver has entered a programming mode and is waiting for the signal from the key. Good luck!
1. Insert the key with a faulty remote into the driver door lock and turn the key to the UNLOCK position 3 times in succession for at least 0.5 seconds each time, and within a total duration of 5 seconds.
: The system should now enter so called a "programming mode" and the window frame LED should blinking once every 1~2 seconds for the next 15 seconds. The faulty remote must be programmed during this period.
2. Aim the key to the (infrared) window frame LED which can be considered as a key signal receiver and press the lock button of the key fob and keep it pressed. While the button is pressed, press the unlock button three times in succession for at least 0.5 seconds each time.
3. Release both buttons.
* After all the efforts described above, the system should now acknowledge a successful programming by flashing the LED once every 1~2 seconds for more than 10 seconds. (Someone said that the small LED on the key fob should also blink a few times; although it didn't in my case.)
