something from the movie transporter

i remember that the guy from the movie transporter had like a digital look with numbers and he needed to type the right code to start the car
how can i do something like that ?

pugeots have in the the older 106's between k/l to p reg. not hard to adapt to another car, not hard to get around either

i wanth to build one
so i am looking for schematics and stuff

u could do 1 thing. program an 8051 to give u an o/p signal on punching in the code. for this u need a keyboard interface ic (i forgot the ic no will find it if u really want). once the code is same as the original code then the lock will unlock. dont ask me how to interface that with the lock. cause it depends on ur car and the lock it uses. i hav and idea though if ur looking out for opening a door lock then u could use a small motor that would pull the lever of the lock inside ur door. if u want this thing for ignition then u hav to get the ckt wired to ur ignition switch and that unlock signal will provide ignition.
i know i might sound confusing c if u understand anything of it
