I get the feeling that most of the people voting plain metal key with no electronics are simply unaware that their key is encoded with an electronic signature that is read by the car to verify that the correct key was inserted. Its kinda like a credit card magnetic strip, and unless your car is like 40 years old youve probably got one of those. You can tell really easily if your key doesnt really look like a house key and just is mostly straight and smooth with barely any notches at all. My car is 16 years old now and its a regular key. Heh. I have a fob for unlocking the doors but it isnt an RF system or anything. If it looks like any of these keys then its definitely not regular, at least not in the sense that its with no electronics. These kinds of keys are not particularly unique and have an electronic signature in addition to any nicks in them to make it far less likely that you can accidentally, or intentionally, start up someone elses car with your key. The protection in the fob for unlocking the doors isnt necessarily as secure but the combination of physical shape and digital signature at least make it very very unlikely that you can start up a second car with the same key. https://i.imgur.com/FpfeiEb.jpg Mine is like the lower right. I never thought of it or tried without the fob. Heh. Honestly, the lower right one is the only one in that picture that Im not 100% sure about, as I just grabbed a random picture of car keys from the web, but Im fairly certain that if you opened up the plastic part at the top of the key youd find at least some rudimentary circuitry and maybe a battery underneath it. --- Que sera, sera. Whatever happens, happens. ...and he was never heard from again. <cite>aDirtyShisno posted [p:929813185] in How do you...
