i think they should bring back passcodes...or at least have the option to use one or have it disabled...as it is now, if i lose my car keys in the vicinity of the car - the cars gone as easy as that...with a code, they would simply have no chance of guessing it...
my old car had one and i thought it was a great idea
as for people saying they forgot it, well as i say you could disable it, but if you choose something memorable then you wouldnt forget it...i chose i parents phone number...no way anyone would guess that
