the seat belt chime and all doors unlock you can do yourself without anything. for the seatbelt chime i think (i've done it to mine but i can't exactly remember) you turn the key on, it will chime and the seatbelt light will go out, buckle and unbuckle the seat belt three times in ten seconds and it should chime again and the chime will be disable. if that doesn't work, try buckling and unbuckling three times in ten seconds before the seatbelt light goes out it's one or the other . the light will always stay on however.
if i can find the paper, the doors unlock has to do with a sequence of pressing b u t t o n s on the key fob. ( for some reason when i put b u t t o n s together, it comes out all funny)website is about like the product
i also have a neat little trick to add cruise to a ST model 03-06 manual and at least an 04-06 automatic for cheap ?? under 40 bucks
and one last piece of advice send the flashpaq packing and get a smarty, i did and i don't regret it . for the simple fact of more adjustibility, and a setting that will fry an auto or stock clutch if you so choose to use it, i tried it for a few miles and it's bad!!! but what do i know, i dont work for superchips, i ve just had two different tuners on the same truck under the same conditions and the same driving styles. man i'm in a smart a$$ mood tonight

i'm sending you a pm in case i get banned.
