The remote should tell you why it is not remote starting. When you press the remote start button, the alarm should beep and vibrate a certain amount of times telling you what is preventing it from starting. Most times, the alarm is not connected for remote starting simply because it is a liability for stick shift cars to have remote start function. The nuetral safety switch could be not grounded or the switch not plugged in, or it may be turned off. Even programming of the alarm could be an issue. I wouldnt know until you give us more info. I will tell you this though, if you never had him hook up the remote start from the beginning, you have alot more work to do. There is a module to bypass the chip in the key for the vats system. Two of which are available: DEI 556U which uses your stock key in order to similate correct resistance to start the vehicle OR DEI XpressKit which acts as a key when wired in place of the vats key system. Im telling you now, if installed incorrectly, the car WILL NOT start.....just know what you're getting yourself into.
