Can't remember how my remote starter works!

I bought a 2002 Elantra this spring. They showed me how the remote starter worked, but now that I need it, I can't remember how it works :banghead: and nothing I've tried has worked so far!
It has three buttons, one unlock, one lock and the asterix.
I remember this much:
-Leave the car in neutral, (it's a standard transmission)
-hit the asterix button to set it. (should my key still be in the ignition? Can I do this after I've gotten out of the car?)
-When starting, I know I should hit two buttons at the same time, but I can't seem to get any combination of buttons to work.... :shakehead
HELP! It's cold out here! :lol:
Thanks!

If it's the same as mine, you have to hit the * button twice.

Thank you! It works! Amazing! :lol: :iceslolan
