Central Locking Key Prob with '97 model

[drew900uk]

Hi - JUST got my boxster, its great and all but I'm having problems with the key and uysing the central locking buttons. Its a key with 2 buttons on it, and when I bought the car, the guy seemed to show it to me OK, he popped the back hood by holding down the smaller button for 2 secs or so and locked the car also. I've been struggling to do this!! I've tried with success once or twice but cant seem to get it to work. I'm just standing there in front of the car pressing the buttons to no avail.

SOMEONE, PLEASE HELP!!!!

thanks very much
