This procedure works on the VW 'switchblade' style key fobs. These key fobs are rectangular with a button on one side. When the button is pressed, the metal key flips out into the straight position, similar to a switchblade.
To replace the battery:
1. Press the button to flip out the key.
2. Turn the key fob so the metal key stick out to the right and the channel that the key fits into is facing you. (The VW logo on the fob will be facing up)
3. Look closely inside the channel. It is split vertically. On the left hand side of the vertical split, it is also split horizontally.
4. Insert a flat head screwdriver into the vertical split and twist. They key fob will split along the vertical line separating the battery compartment (on the left) from the key (right).
5. The battery compartment (left) can now be pried open along its horizontal split.
6. The replacement battery is a 3 volt CR2032 lithium 'button cell' and is commonly available.
7. Replace the battery with the + side facing down.

You normally do not have to reprogram the key when you replace the battery. If you do you will have to contact your VW dealer.

Need the year and model VW to answer the question.
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.

battery can be bought at any Radio Shack.
Find the little slot on the side of the fob near the PANIC button. Insert a small flat blade screwdriver or a paper clip into the slot and twist to separate the 2 halves of the fob. Replace the 2 CR 2016 3 volt batteries and snap the fob back together.
Usually the key FOB has a trunk latch, but if the battery runs out or you don't have a key FOB, check next to the drivers door, next to the gas release lever, there should be a trunk release lever.
What Model and Year is your vehicle? For a VW Golf (Mark IV 2000), Place the fob with the VW logo upwards. Prise apart the sleeve with the aid of a screwdriver along the join in the middle of the fob. One section has the key, the other has the transmitter. Gently prise open the transmitter top to access the battery which is in the lid. The battery can be easily removed, but note the orientation. A plus (+) sign is shown on the lid to indicate the way the new battery should be installed.
There is nothing to reset. Just change the battery and if you have it in correctly it will work.
I have a Toyota, and my key fob light stayed on also. I called the dealer, and they said the button on the fob was stuck down INSIDE the fob. So, I simply unscrewed the screw on the back of the fob, opened the fob, then put it back together. The fob was fixed. I didn't have to fix anything in the fob.
