Keyless start
 

I was in my friends FX45 today, and he has the 06 so there is no key, you just get into the car and turn the knob and start the car, i thought it was really sickkk... anyway you can make this same system possible for an 05 8??? any suggestions would be appreciated!

I have this system with my 06 shinka. I think it's just a transmitter and a set of credit card like keys.

You should be able to buy it from mazda parts suppliers - may pay a lot though.

I have Shinka also and it's cool except for getting used to the bipping at different times. The system has a few nice features but would not pay extra for it. The card size tranmitters fit good in the little pocket of my jeans. :)
