Alpine Unit

The nuber to my Alpine alarm in SEC-150R, its the one with impact and 2 stage radar

With ref to the immobilizer system, my vehicle is equipped with one I had a look at the Hyundai electronic manual last night while at the dealership, it appears to have all kinds of parts to the keyless entry, there is the SMATRA, ETACS ( i think thats part), a burglar relay by the steering column. 

I have also been told that bypassing the factory alarm will fry my comp, is this true?  The dealership told me this, I honestly think its a crock because they also told me that I couldn't remove the factory stereo but that was a lie, unfortunately my alternator isnt quite strong enough to power the system properly.

Thanks again
