"2012, 13 months old, 31000 mi, got the low key battery message. Took a safety pin and stuck it in the seam of the two black pieces at the top of the silver and pried it back. Silver part popped right off. Then used the pin again to pop open the battery tray. give that a try."

Page 39 in your manual:

Wish VW would provide as a PDF. Pathetic.

Yes, I have found a safety pin, or a bulletin board push pin to be best. Slide it in at the top of the hole then push gently in the same direction so that you lever the internal plastlc catch back down towards the main body of the fob. A bit of fiddling the first few times, but when you see how it works it's simple. All you are doing is depressing the plastic catch arm which drops the catch out of a little hole in the chrome cover.

BTW, that works on the other side too, to access the chip.

No, it'll be just fine. Just replace the battery (right way up;-) , of course) button it up and you're good to go. The programming is for the transponder chip.

Thanks! I tried popping off to access but no-go. There's another reason med school was not an option. Battery is fine but my skills need work.

It does take some fiddling - and holding your tongue just right - the batteries are also available at Advance Auto Parts stores, Ace hardware and Batteries Plus stores...
A funny caveat - my wife will carry her fob along sometimes - the warning came on saying that the battery was low after I had just replaced it a few weeks earlier in my fob. Not knowing that she had her fob onboard, I was perplexed that I had bought a depleted battery. As we drove back from the parts store with another battery, I asked her if by chance she was carrying her fob when the warning came up - yup... when you replace one - replace both of 'em...

Touareg 2 Key Battery Replacement Youtube Video

I had the same issue with the manual being a bit weak to do the battery change on your own. It was so difficult (mainly because you don't want to damage the pretty & expensive key!! ;)), I decided to shoot a quick video. Hope this helps...


Thanks, E

I suppose that by ignoring the manual instructions, and guidance given in this and other threads earlier, you have managed to open the KESSY fob by leverage and force. However, by not depressing the secondary latch on the emergency key release, and completely ignoring the latch on the chrome side panel, you have, at best, started to deform the internal retainer catches on your $300 key, and at worst, broken them off completely, and have them floating around in there, ready to jam up the works...
Extracting the emergency key, and opening the fob are both extremely easy, if you follow the directions carefully, observe the opened mechanisms, and understand what you are trying to do.

The manual I have (2012 model) has an incorrect illustration on the hole you are supposed to put the pin/paperclip (all high tech tools btw) in. But...being that I'm and engineer, I could logically see the illustration was wrong and tried the heavy paper clip...I applied pressure where I should have, in the correct hole and it still didn't open (my key must have had a better mold/casting than yours...nice tight fit ;-)). The eye glass screwdriver I used created no marks and was much easier. So the video was not intended to help VW technicians but rather the average "do it your self" person not wanting to run to the dealer. The emergency key was easy to remove as well..no issue there and I think I can probably open and close my key at least another 50 times before the chrome side falls off. This brings me to at least to 2063...my Touareg and I will be dead by then but on lives the key! ;-)

This thread and having read the owners manual were a huge help today! I accidentally dropped the key for our 2012 tdi sport in a parking lot today and then tried unlock the door and the magic didn't happen... I had to pull out the plastic emergency key, pry the cover off the door and unlock it with plastic key. It was flexing but it turned the lock. I had not had any indication of a low battery so I looked up this thread, used a sharp pointed pocket knife to release the fob battery cover, then pulled out the battery and put it back into the key. Once I did the indicator light once again turned on when the buttons were pushed and key worked fine....
