how do I reprogram my car's stock keyless entry to perform different functions than what is

Ben

assigned? I am located in Japan, but I'm from the US. I spend my time over here learning as much as I can about whatever pops into my head. Some time ago, the keyless entry fob broke. I super glued it shut, due simply by the fact that it was going to be upwards of $300 to get a new key fob made. When I was younger, I heard of people reprogramming their keyless entry to respond to different commands. Mainly in German automobiles, but that was 5 or so years ago. I am driving a Toyota Altezza (Japanese version of the Lexus IS300). it has laser cut keys, like on most cars these days. My key fob has only 2 buttons, so I was going to order a Lexus factory key fob, containing 3 buttons, and do a little modification of the buttons and what they actually do.































I have heard of having a button to put up your power windows, and modifications among those lines, on cars like the Volkswagen GTi. I was really looking for something like that, plus maybe a 2-button combination to have remote start capabilities.































Any information on where I could get this done, how I could get some software or a general direction to point me would be greatly appreciated. I have 2 valet keys, which I don't ever use, so if it came down to it, i heard you could replace those in your car's computer with the other functions needed.

Assuming yours is programmable (look in the back of your owner's manual, it will describe the different possible settings), any Toyota or Lexus dealer can do it. If you're a regular customer, they may do it for free. If not, it shouldn't be more then $50 or so.
