question on aftermarket keyless entry?

I have a 92 G20...it has leather and the factory alarm, in 92 they did not come with remote entry or remote disarming of the alarm..
the alarm is disarmed by the key being turned in the lock..
my question is..can I install a aftermarket keyless remote/remote starter system to my car without losing my factory alarm? I am pretty sure yes..but was wondering if anybody had any experience with it..

c'mon....anybody?

for you to install an aftermarket on added to your factory alarm you have to go to parts at infiniti and get the schematics of how and where they hook up the factory unit to and the sheet that says where each thing is suppose to be plug in to then you take that to a shop and give that to them and they should be able to do it for you if you dont get the map from the dealer then every shop you go to will tell you sorry you have to get another alarm to get the keyless entry

i'm 96% sure on what i just wrote to you
your easiest bet would be to get installed through the dealer try talking to your salesmaan to see if he or she may be able to help you out at all
if i dont answer good enough sorry at least i took a crack at it


i have through this same map crap because i want to install remote windows
later
