need alarm 2001 olds alero

I have a 2001 Alero with factory keyless entry. My question is Im wanting to install a Auto Command alarm with remote start. Will i need to disconnect the factory system to install the aftermarket alarm? I broke my alereo oem remote and im wanting a little bit more protection. The auto command states:     * Up to 1000ft. Range     * Warm up and defrost, or cool down your car by remote control     * Save Time and extend engine life by having your car all ready to go     * Car cannot be driven without your key     * Remote start relays on board     * Selectable run times     * low voltage check     * diesel mode     * quick stop option     * no-tach installation     * nuisance prevention circuitry NPC     * 3 zone alarm system     * alarm zone bypass     * passive/active arming     * starter disable     * auto rearm     * auxiliary output/trunk pop     * ignition controlled door locks     * daytime running lights     * parking light relays on board     * keyless entry outputs **** KEEP IN MIND it uses the factory horn and the siren and that this does not have a shock sensor **** I called around and my stero shops want 50-60 dollars and hour and they said 4 hours of work. I can do this myself with your help. Yall have helped me before. Can you guys help me with this one? I dont have 200 to spend getting this thing istalled. I dont have to have the remote start but it would be nice. I dont want to mess anything up.

Well if you want to install r/s like you stated, you will have to disarm the factory alarm during remote start if there is an actual alarm. Just because the car honks when you lock the car with the factory key fob doesn't make it an alarm. You do not have to disconnect anything to do an alarm. You will have to wire into existing door locks, lights, ignition, starter, etc.Big Al

how can i tell if my car is equipped with a factory alarm or just key less entry? also is there a way to disable the factory key less entry before i install my new system? the new alarm is equipped with key less entry and i want to make sure i wont mess anything up before i install. thanks for any and all help.

im still having trouble with this alarm, i cant find anything about resistors or relays for my car or how to wire them. do i need resistors for the power locks? where do i put them? do i need relays for the locks? where do i put them? where is my door trigger wire? do i need diodes? this alarm is causing major frustration, and i can afford to take it somewhere to have it done, they want 250+ dollars to install this system

im almost done with my alarm install. Im stumped and i need help. Where do I tap in for the parking lights so they flash with the new alarm? Do i need a relay? wiring diagram? What diode do i need for the door trigger? i bought some from radio shack but im not sure if i got the right ones.
