Replacement Key Fob Shell Case fit for VW Volkswagen Jetta Passat Golf Beetle Rabbit GTI CC EOS 4 Buttons Keyless Entry Remote Key Housing with Uncut Blade (Black)

Worked and fit perfectly. I expected some cheap 3d print feeling plastic, but this feels like the OEM key.

This is a perfect replica of the original VW key fob minus the internal circuit board and RFID chip, which you can transfer from your original. I was able to get the key blank cut to match the original by taking it to a hardware store with up-to-date car key duplicator, and it was a free dupe because I brought my own blank (that came with the fob). Then I opened up the original fob, removed the circuit board and battery and transferred them to the new fob. I open up the upper part of the fob (removing a tiny phillips head screw) and removed the small glass ampule containing the RFID chip, then transferred that to the new fob with a dab of glue to hold it in place. After getting the new unit all together I tested it in my 2005 Jetta and it worked perfectly. Installing the RFID chip into the new fob and especially the process of reassembling the spring and latch for the switchblade action was the hardest part, and I wouldn't recommend it for anyone lacking mechanical understanding and the patience to keep trying until you get it right. It's probably possible to remove the RFID ampule without disassembling the upper case by fishing it out of a small hole if you know where to look and carefully pull it out with miniature tweezers. The ampule is glued in with a soft glue. The chip is read by circuitry around the ignition switch and the code number is relayed to the car's anti-theft security system that VW calls an immobilizer.

I bought this for the new buttons because mine were worn. I only swapped the bottom piece. I took the chip out. To program these, they require you to cut the key, program the button chip and program the immobilizer chip. I just wanted to make it look better. The key portion fits on the top of this, but it's a lot tighter than the original. No tools really required, but a screwdriver or something to pry the bottom apart and get the chip out will help. I looked at buying a full replacement, cut and programmed. They do it at a local company using the same thing and charge $178 for everything. Good to know that this is the same product. Pictures show how these two parts fit together if you're just looking for new buttons and your key works.

Used this to replace a broken hinge on a factory keyfob. Worked well without too much effort.
