Step #2: Carefully Open the HousingPrevNext
- The best methods for disassembling the housing will vary from model to model. I have a HID ProxKey 1346 Proximity Keyfob. This model has a seam around the middle where the two halves are glued together. So I initially tried to pry it open with a screw driver and then a knife. Unfortunately the seam was too shallow and the plastic was too soft for this to be effective and I only succeeded in scratching up the surface.
- The best method that I found for opening this kind of housing is to crack the glue seam by squeezing it. I wrapped the key fob in a napkin to avoid scratching it. Then I squeezed it at one end with a pair of pliers perpendicular to the seam. This caused the two halves to separate slightly at the end. I stuck a screw driver into the opening to hold the two halves apart. Then I repeated this process moving down the side of the key fob until the two halves where mostly separated. At this point I was able to just pull it apart the rest of the way with my fingers.
- Alternatively, you can cut the housing open with a knife or rotary tool. If you do this, then you need to be very careful not to cut too deeply or you risk hitting the chip.
Step #3: Carefully Remove the RFID chipPrevNext
- You need to be extremely careful when removing the chip! I broke the first chip that I was using for this project. So be aware that RFID chips are fragile and it is very easy to accidentally break them. If possible, you should avoid applying any direct pressure to the chip or its sealant.
- I decided that the safest way to remove the chip from its housing was to cut it out with a rotary tool. First I cut off the bulk of the attached material. Then I carefully shaved down any remaining chunks of plastic. Remove only as much plastic as you absolutely need to. The more that you cut away, the more you risk damaging the chip.
Step #4: Choose a New Housing For Your RFID ChipPrevNext
- You can use anything as the new housing for your RFID chip. For instance, you could put it in your wallet or inside your cell phone case. However, considering how fragile the chip is, I recommend using a housing that has hard rigid sides such as the inside of a multi-tool. Or you can get creative and put the chip in something unusual.
- My favorite housing for an RFID chip is an ordinary stick. That way you can wave it around like a magic wand and it will actually do something like unlock your door. To mount this kind of chip in a wooden dowel or stick, all you have to do is drill a hole in the end that is just big enough to fit the chip.
