I have a 2009 chevy 1500 ltz and want to hook up a tilt switch and still use factory remote is this possible

 

ok, in english......what is a tilt switch? how do you interface with the tilt switch?

 

Its a digital tilt switch. If the truck is lifted by a jack or tow truck it sets off your alarm

 

Yeah, thanks for clearing that up, my WIFI's been screwing up my mind reader a lot lately.

What a lot of security minded people have been using in recent years is a concept called "layering". In essence, it puts security for your vehicle in layers, each powered and tripped independently of the next layer. Generally there's a real sensitive ("icing" or "frosting") top layer specifically designed to set off the lower, less sensitive layers in the event of illegal
activity. There are also "dummy" shutoffs to head-fake the would-be alarm "PRO".

This not only creates a system which is much harder to disconnect, but is also much easier to trip.

So many consider that hooking up all the security to one circuit is a choice which leaves your vehicle vulnerable.

Add a shock sensor to your factory security system. Set the sensitivity really high and it should detect any type of movement.
They also have a pin switch for the tailgate

 

I have the factory keyless entry and was going to add the GM shock sensor to it. Can I add a aftermarket digital tilt switch to this? I know GM makes one but its mercury and very sensitive.

 

If you know how to wire it properly, you theoretically could use an aftermarket switch.
There are 4 wires to most shock sensors and I assum there would be 3 or 4 to the tilt sensor. Power, ground, warn away, and full alarm. First of all you need to find out if the triggers work on positive or negative voltage. If it works on negative(shows ground when triggered), you can hook that wire to the door pin wire. That way when the tilt sensor triggers, the computer will think that the door is open and will trigger the alarm.
