alright i just bought my 300zx and it came with an aftermarket alarm system however it did not come with the remote..when i go to unlock the car sometimes it will go off sometimes it wont..sometimes when i put the key in it will go off sometimes it won't..a nissan mechanic that i know told me unlock the passenger door then lock it then go around unlock the drivers door get in and go...that works, but then after a few seconds the alarm will go off again..i ended up disconnecting the alarm horn so it doesn't go crazy in the parking lot but the lights still blink...is there a way to get this to stop? or do i just need the get the alarm ripped out and a new in there or can they program a new remote? if it helps to know the name of the alarm i will look in the morning...if anybody knows anything let me know..thanks
