2004 Denali alarm?

I just had the 791XV alpine alarm installed at a local stereo shop and they disconnected my security chip(The one you can take out so that you can't start the truck without it).They told me that this alarm would not work with that chip installed.Forgive my ignorance but isn't the chip just a normally open relay,you put the chip in and it closes the relay.Why would this securtiy chip be incompatable?

You might want to go to this shop and ask them exactly what they did to bypass passlock II.  I have done many of these and I've never heard of removing the "chip" from any of them.. Check your receipt and see what they charged you for? Is it just an alarm or remote start/alarm, I am not famalier with  that model? Sounds a little fishy though

are you refering to a passive alrm system?  The "chip" being a module you plug into a receiver to allow the unit to start.  If so they should still be able to use this with the new alarm you had installed as long as you aren't trying to remote start the vehicle.

The alarm is a remote start alarm (Viper 791xv) , and if i'm not losing anything or gaining anything without having the chip i feel better about it to a point because i should have just not purchased it when i bought the vehicle and bought a quality alarm instead.
