the short version -

sit in the car with doors closed.

key on (dash lights on, but not starting car), click remote, key off.
do this 4 times, on the 4th time click each remote that you have, twice. that's basically it. if you were successful, you'll hear the power locks click, probably twice.

for more complete instructions, do a search, this has been covered before. also, you will get better results by starting your own post in the correct forum. threadjacking is not polite.
