Could the key fob circuitry be put in another vessel?

    Say I want to take my key fob apart, put the guts in something else, let's say a sonic screwdriver replica, would that work? Would it fit?

    Answer 1) if you never need to press buttons, (you always keep the fob in your pocket) then yes, anything non-metallic you can put it in should be fine.

    Answer 2) If you need to press the buttons, I would work at encasing the entire fab in the new shell.

    That's way too big. :( I don't want to carry that around. At least a sonic screwdriver can fit in my purse.

    It's easy enough to take the circuit board out of the keyfob. Just insert the end of the mechanical key into the screwdriver blade size opening at the end of the keyfob and twist. The case will open up, and the board can be removed. Or just follow any instructions for replacing the battery.

    The simplest protective enclosure for the circuit board would be one of those small ziplock bags sold for pills. Just don't sit on it...

    Take the mechanical key (with your house key attached) out of the fob. Leave the fob in your purse and keep the mechanical key(s) wherever you think is best.

    Just curious, Why? If you keep it in your purse what difference does it make how it looks?? Security? Or just Fun?? Not being critical, I just my like your reasoning. :)

    If you can get the Tardis version of the Sonic Screwdriver, you should be good to go.:)

    Not sure how similar yours is, but the circuit board for my fob is surprisingly smaller and better shaped for a "cylindrical" cross-section profile than the one from my old Sienna:

    width: 20mm (22mm including the battery bracket, which is moddable)
    length: 45mm
    thickness: 9mm (both battery bracket and chip foam rubber cushion are flush)

    For the sheer pleasure of saying that I can open my car with the sonic screwdriver. Can't tell me that wouldn't be awesome?!

    That would be a good one too! Hmm. Now I'm going to look for one.

    Considering the replacement cost of fobs, I'd try to let go of this notion.
