I saw where they have a "doohickey" for changing the house code on a palm pad.
The price was OK. BUT the shipping was $9.95 or $9.99 or something like that.
Made it not worthwhile.
Anyway, I had a broken CD case. So, I used my trusty razor knife to cut off a small piece.
I then removed the cover of the palm pad and gouged out an area at the top with the razor knife. (Not to worry. There is plenty of room.).
After making sure that the piece of CD case would fit in the code wheel slot and turn it easily, I put the cover back on.
I then fitted the piece of CD case into the gouged out area of the palm pad, put pack the code list & cover.
Viola, I now have a built in code wheel key.
The whole thing took only a couple of minutes.
It would be a whole lot neater to use a dremel tool to do this.
