This has been discussed before. Here is a better alternative:
Read up in the Ecuflash forum on the tephra mods. Buy yourself a tactrix cable and patch your ecu with one of his patches that included valet mode. Then set the valet mode rev limit to something like 0(I cant remember if you can use that exact value but w/e) Now whenever you park your car and dont want it to be started put it in valet mode. IMO thats much more practical than bringing your laptop everywhere and re-flashing it everytime you want to drive your car.

Someone explain how they are going to steal it without a key...

I don't want to sound like a dick but the second you think like that is the day your car will get stolen. There is always a way around that. You could spend $10k on an alarm system and someone will find a way around it. The cheap and easy way to keep your car from moving from where you parked it is to put an on/off switch in the fuel pump circuit and hide it somewhere.
But you do sound like a dick because the car has an immobilizer matched to the key.

Fuel pump relay switch is a great idea. But something tells me people who could bypass your immobilizer would simply do so by procuring a key matched to your VIN by reading your VIN plate on the dash and having a connection that could get them a key to your car.
Thieves of this caliber would most likely find your fuel pump switch.
Or they would come with a team and simply haul the car away on a flat bed and none of the rest would matter anyway.
In the end this isn't gone in 60 seconds. It's real life. And while I'm sure car thieves of that caliber DO exist. What would they want with a 20-30k evo?
They would be after MUCH bigger fish than anything we would own.
The more likely / and easier scenario given the state of immobilizer... would be them simply getting the key from YOU using force or threatening to say shoot you in the face. Like a car jacking.
