Every time you start your car the alarm comes on and wont start?

That's because you need to disarm the car alarm if you dont have the remote. To do this on the driver side there should be a fuse box. Open it, look for a little black button. Press it 5 times not too fast or to slow. After you've done this, you should hear the alarm beep twice and the little red security light should be steady instead of blinking. This works believe me!
