hahaha "bugs" its "bucks" not bugs, thought that was funny. i work with a bunch of mexican guys at lexus and they are trying to teach me spanish, so i get laughed at all day cuse im horrible at it. also yes steffen is right, you cant just mill a key and have it work there is a chip inside the key that is married to that particular car, if you lose a key your screwed, as for cost, not sure about it but how bout you ask your dealer have all the paperwork written up like your going to buy the car then refuse to sign it until they order you a new key at no cost, they wont back out then...goodluck!
