It is funny actually, why didnt they fit a proper alarm or immobilisor on the IS200/Altezza?
I went with an aftermarket alarm the week I got my Altezza, got a Dynatro 5Star alarm, triple immobilisors, dual backup batterys, and all the other normals like shock sensor, touch sensor, car locator blah blah blah.
Cause in NZ if your car has a 5Star alarm, insurance gives us up to 15% of our premiums, so the alarm pays for itself after a while lol
