    I wanted to make the key and the fob for my Scion one item.
    First there was the key and the fob. Merge into one.

    If you remove the plastic around the key there is a metal tab on the end of the key that can fit into the casing. That is if you cut a hole in the side and glue it in.

    Aight. Here is a little more about the mod:
    Opening: You can see that the gasket is a little deformed due to the key being inside the case.

    Open: The hole is cut so that it is level with the bottom of the case cavity. The hole should be about the same size as the largest part of the key. (You will have to add clearances so that the key can fit all the way down in the cavity.

    Tools:
    Dremel (Cut Hole)
    Soldering Iron( Open Hole Up)
    ShoeGoo (Glue)

    Now I need to find a way to attach it to my key chain.

    excellent. I will do mine tonight. I have a camry so it will be slightly different. You can probably drill a little whole on the top and slip a fine strong thread through it and attach it to your keychain.

    Very innovative!

    :thumbsup:

    My wife's Ford Focus has a giant key fob remote, as well as a giant key. I hate them both and will never carry the key fob remote. I wish your idea would work for me, but I don't think I'm willing to try it. Read on for why...

    Just a word of warning here for those wishing to attempt this... Some of the newer (larger) keys have a built-in RFID unit that has to remain intact for your key to work with your ignition switch. If you damage the RFID part of your key you might have to replace the whole key. From what I've heard, it can be pretty expensive.

    Usually if they are going to put in an RFID tag it will be on the chip board or a sticker on the case. It would be too expensive integrate it in the case. (I am a mechanical engineer with experience with automotive injection molding.)

    Just open the case and see if it will work. I take things apart all the time to see how they work. Only if you feel comfortable doing it.

    sorry carlos

    Get some plastic weld stuff and weld the plastic part on the key to the back of the key fob.

    I would look into using a Acura flip key. My brother modified his Element Key using an Acura Flip key they had the same electornics. I was looking to do that my Lexus doesn't make a flip key that matches my scion electronics.
