I am not sure I should get involved in this, but I think I might know how a remote start could work. Basically, you would need another programmed transponder. That would be put in another reader coil in the remote start that would be relayed to the coil reading module instead of the original coil when the remote start was activated via its transmitter. So, unless the remote start transmitter was used, it would function normally. If the remote start was used, you would still need the mechanical key to unlock the column and drive the car. I would assume there are interlocks for the parking brake and some sort of neutral safety mechanism.

So, the only real danger of cars being stolen would be by having that extra transponder in the car that is used by the remote start. You would need to know it has the remote start and where it is, then remove the transponder and put it in a key that would work in the lock so you could use it as a normal key. If the remote start's transponder was glued in, it would be extremely difficult to do this, to the point I would say the risk would be negligible.

As for the remote start, it would need to energize the 86s terminal when switched over to the remote start transponder. That would make the coil reader module read the transponder and start the transponder authentication process. Once that is done, you energize the ignition and then starter.

All that said, I have never installed one of the devices that is mentioned, so I have no idea how the configuration needs to be set up to get it to work or if the device in question can do this, but I would bet it can. I personally wouldn't put one in my Boxster, but YMMV.
