Stereo & Electronics - Question about alarm

Whats up everyone,
Whenever i lock my car (99 Z28), it will do the two beeps, then pause for a couple seconds and beep another two times. my friends drive a 98 and 99 Z28 and neither or theres do the two delayed beeps. is there a way to change it so it doesnt do that? thanks for the help.

ummm i believe this has been asked before and i think it may be your hatch doesnt quite think its really closed.....

already checked that..hatch is definetly closed

When my hatch isn't fully closed, it only beeps once when arming it from the remote. There's a bunch of different "Modes" you can program in the owners manual but didn't see delayed/secondary beeps when glancing through mine. Maybe start from scratch and reprogram? Just in case you need a manual http://shbox.com/pdf/manuals.html An alarm that goes off with lights and horns just after arming is usually a bad shock sensor.

awesome ill look into it more tomarrow. thanks for the help guys
