Can't Program Viper Rattler 300

Bought a used 2002 RAV4 that has one of these in it. I want to get into program mode to shut off the Autolock feature, but can't access it.

It seems that the unit when installed- does not use the door pins as triggers. I can open the doors and close them gently, and system does not go off. Only when I slam the doors does it go off(shock feature).

Is there another way to program this thing, or will I ned to find the wires that WOULD have gone to the door? The manual says that you ned to open a door first before turning ignition on and off.

Hey Chris,
I found the installation guide at

this should have programming instructions.
I thought maybe you could help me with my problem too. My battery died and I'm having trouble resetting the alarm. Let me know if you have any ideas. Thanks
