Adjust Installed System

How can I adjust an existing alarm system to NOT reset itself when left alone.  I need it to set only when the owner pushes the remote button.  2000 Toyota Tundra v8 4wd Access Cab

Need to know more about the alarm, Make? Model? Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

Ok, If this is a factory RS3000 setup, try this. Insert the key into the ignition switch, turn it to on, not acc. Using a remote control, press and hold both buttons at the same time for over 2 seconds, until the Status monitor LED turns on. You must perform the next step within 30 seconds. Press and release the top remote button twice, there should be 2 chirps, and the exterior lights flash twice. Then turn the ignition switch to the lock position. There should be 3 more chirps and exterior lights should flash 3 times.
