remote entry question
 

i haven't had this '96 Protege LX 1.5L long so I am trying to work out all the kicks. My remote has a sqaure blue button (with headlight symbol on it) at top left, triangle black button top right, circle red button bottom left, upside down white button bottom right and the word MAZDA underneath all of that. NOW, the top right button (black triangle) unlocks my doors. All the rest lock my doors. The alarm arms when i lock the doors with remote. Is it supposed to be like this?
