read 24c16 eeprom - car stereo help

Hi Guys, I need some help with something a project i am planning, i have been given a vauxhall stereo that is missing it security code, ive been told i can read the eeprom from the stereo and with some software available online decrypt it and recover the security code.

im running out of options to recover the stereos code and its a shame to throw out a working stereo if i can get it working again, the dealer needs the cars license plate it was fitted to at the factory as they store a set of license plates to stereo code records but without the original license they cannot give me the code. i would use the online decoders to-do it but that requires the serial number which has long since rubbed off :( . my only option if i cannot recover it with my arduino is to pay someone to recode the stereo and whilst its a nice stereo its not worth the money to recover.

reading eeproms is a new world to me (i spend most of my arduino time making leds flash) and would appreciate some help with how i get the arduino to talk to and read from the eeprom on the stereo, ive found the data sheet for the eeprom but im lost with how i would wire them together and talk to it?

im not after an easy ride and am willing to try some coding im just after some pointers on how i connect them and some suggestions on talking to it.

here is a pdf link to the eeprom if someone can point me in the right direction, its an atmel chip if thats a good thing. http://www.datasheetcatalog.org/datasheets/208/160469_DS.pdf

thanks everyone

hahaha nope no where near there, i live in south wales, UK. and being honest id not be mad or dumb enough to post on a forum about how to unlock a stolen / dubious background stereo lol , its a genuine stereo which is just anoying me sitting in the corner of my room missing its security code :(
