Stupid question and an Interesting Challenge

[thstone]

If I understand correctly, here are my thoughts;

The linked article showed how to install a generic start button to bypass the electrical key switch. This should start the car as long as the immobilizer pill is within range.

However, don't forget that you will also have to bypass/remove the mechanical key link which locks/unlocks the steering wheel.

Also, you'll have to make sure that the wiring/signal interface between the Adruino start button controller and the starter relay is the same for a Porsche Boxster as a Honda Civic. My guess is that its similar but probably not exactly the same.

I would suggest having someone who is familiar with electronic circuits and programming embedded devices as a helper on this project as the odds are high that you will have to modify the circuit or the programming.

Last, will you need a new Porsche fob? Why not just keep the old one in your pocket (or place it close enough to get the car to start). The old fob can still be used to lock/unlock the car. You could even remove the key shank and just carry the fob to make it smaller and easier to carry.

Can it be done? I am sure that it can. Only a question of how much time you're willing to put into the project.
