New MK6 Key Fob?

[migranitas]

I'm trying to open the VW KeyFob, I saw some images here and read some info, but nothing give me the soluction, so I post some images showing the SwitchBalde without external parts...



The Black VW logo has removed too and no screw was founded as some images on threads show it...



The hole can be one open case possibility, but I try to sting inside with no results



Below the button panel there wasn't any way to open the switchblade case...





Can some one have the solution or any guide to access to the circuit card...
THANKS!!!

Hard to believe no one has determined how to do this... Or if it can be done.

So far migranitas , you've done the most taking apart, if you find out, please let us know too!

Maybe the next mystery is getting under that emblem cap. Maybe that is where the fastener is similar to older models where the screw was directly under the emblem. I tried to remove that cap but it seemed very secure and did not want to further disfigure the damn thing.
Anyone willing to sacrifice their MKvi fob for the sake of automotive scientific research???

I know VWOA sells replacement emblems @ something like $3 each which leads me to believe there has to be some kind of access under the logo.

You can make a small hole under the emblem. If there is a screws the problem is solved

OK, well I solved this issue. You cannot take the key apart or replace the chip without major surgery. I bought a key from a wrecked car and destroyed it to find out what was inside and how to take it apart. Here's how to split open the case:

1. Drill out the pin shown below and pull it out. It's locking the entire case. You could also use a hammer and very thin punch to push it through the plastic wall that's on the other side. It may also be possible to drill from the other side and then push the pin out. As long as you drill straight it won't hit the chip inside. Mine is crooked because it bent when I pried the case open. It cracked the plastic pin keepers holding the metal pin and in my case also split the key fob sides. You may also be able to drill the plastic pin keepers holding the metal pin down by drilling two holes just to the left and right of the pin. That should weaken the plastic pin keepers so that they'll break first when you pry the case open.

2. Once the middle pin is removed (or you're ready to give it a crack, literally), pry the case open at the metal key end. The other end (key ring end) has a hinge and it will open like a clam shell. There are some short hooks holding it together but they'll come apart easily.

That's it!

Biggest difference in internals is that the immobilizer chip is no longer a separate pill that's glued to the plastic. It's now part of the circuit board and the solder points are covered with glue. The immobilizer chip long black rectangular chip. If you separate the chip from the board it won't work. This is unlike the older keys which had a separate immobilizer pill which worked independently. I believe this design change was to give additional range for KESSY. The good news is that if the remote battery is dead, the immobilizer chip will still work - you just have to hold it next to the ignition switch blank off plate to pass the signal. So if you want to replace the chip, you'd have to figure out what and where to buy a replacement chip, remove the glue, desolder it and solder in a new one. IMHO, way too much trouble for the amount of time and money saved. Like the last few types of remotes, once a chip is programmed to a VIN, it will only work for that VIN. It cannot be programmed to another car. Since the remote half and immobilizer chip are on the same circuit board, there's no use for a half key, unlike earlier cars.

Therefore, I will change my recommendation for the new mk6 style keys to: if it's broken, go out and buy a new one. The only case where you may reuse it is if the key loop or metal blade is broken, and even then, it's a huge pain to split it open. The good news is that if you drill or punch the pin out, the clips are strong enough to hold the key together. The pin was put there to lock the case down.

That sucks....I was hopeing that after a few years, my key fob was all banged up and worn, I could just buy a new empty case, and swap everything over....it looks like that won't be happening. I wounder why VW made it like that, so you would be forced to spend $$$ on new keys...

[whiplash willy]

So you have to break they MK6 Key Fob to get it open. I wounder if you do that, if you can put it all back together in the older Key Fob Shell like this one:

They look to be the same from the outside..

well I've searched ebay and looked long and hard at the pictures and my best guess is that yes, the new style replacement case will fit the new style key internals. You might have to trim the plastic worst case but I've held the chip over pictures of cases and it looks like it will fit.

Just to be clear it has to look like this, not the earlier split key. Even though it uses a screw under the badge there's clearance for the chip.
