Removing the battery cable is something the alarm companies no the theifs can do. Find the valet button, this along with a few steps that you can find with your alarm manual will reset the system.

the BCM (body control module) is a problem on these cars it works one day and not the next,also controls the lights, security, door locks, etc this computer is usually very expensive and dealers charge around $800 the replace and reprogram it.

The RDM or Rear Differential Module on these GM vehicles (Vue, Torrent, Equinox) is a known weak point. It is most likely shot as the trans outputs power to the front and rear equally; gearotor pump(s) in the RDM then assign traction to each rear wheel if the wheel is turning slower than the input. So if it is still turning it must not be transmitting that torque to either "braked" rear wheel... There was a recall for the RDM in which GM quietly increased the slippage at which it engauged the rear wheels due to high failure rates...

The problem is under the Horn push ,in the steering wheel/column. Somewhere the contact plate connection has detached, and is making a direct supply contact to the Horn feed wire, when the ignition is On...As a temporary emergency bypass, remove the power supply wire at the Horn.
