Questions about My Viper 300 alarm

Hi, I just bought a used car and want to make some changes to the settings on the alarm. 

I'm following the instructions to setup the viper, but I must be missing something because the alarm doesn't seem to respond.  Basically start off sitting in the car (key in my hand and door closed).  I open the door.  Put the key in the ignition, start the engine, immediately turn off the engine, go to the valet switch (an on/off position switch, which is at "off").  I move the switch to the ON position, Off position, On position, off position, on position, off position, and finally ON position and keeping it there.  Supposely the alarm should give me three chips indicating that I'm in option menu #3 right?  (all while the door remained opened).  The alarm was professionally installed, I'm trying to add ignition door lock feature.  I'm following the instructions to setup the viper, but I must be missing something because the alarm doesn't seem to respond.  Basically start off sitting in the car (key in my hand and door closed).  I open the door.  Put the key in the ignition, start the engine, immediately turn off the engine, go to the valet switch (an on/off position switch, which is at "off").  I move the switch to the ON position, Off position, On position, off position, on position, off position, and finally ON position and keeping it there.  Supposely the alarm should give me three chips indicating that I'm in option menu #3 right?  (all while the door remained opened).  The alarm was professionally installed, I'm trying to add ignition door lock feature. 

Another question is that I'd like to buy a remote trunk release for this car.  If I buy the DEI trunk device, when popping the trunk open, does it disable the alarm?  can anyone explain how it would work?   Since right now, if the car is armed, opening the trunk (manually) will set off the alarm.

Last but not least, I found some cheap trunk release on ebay for about $20 shipped, versus $50 shipped for a DEI branded one, is there a difference?  Which should I get.  Thanks

Hrm, still didn't get it to work yet.  Will try that this weekend.

Can anyone answer my other questions though?  About the trunk release>

Thanks

David

Actually I did look at that, but it doesn't tell me how the remote trunk release would work.  I just want to know if it will disable the alarm when the trunk is poped.

Thanks

are you sure the toggle switch is plugged into the blue port on the alarm and not hooked up as a rem. start kill?

check the alarm to be sure.

Thanks for all the help guys!

That trunk release is too cool!  It even rearms the car for you!  that's nice.... Since I often disarm my car to manually open the trunk and then forget to rearm the car.  I got good news for myself :) I checked my Viper 300 (original 300)'s manual on http://www.drdetailshop.com/deiinstallguides.htm  and found that it does have the ignition controlled door locks.  I will take it to a friendly mechanic this weekend to get the feature turned on.

Thanks
