I've got a CrimeStopper 2-way alarm with a remote that's loud enough to wake me up, so I don't need the siren  while parked at home. Is there any way to add an on/off toggle for the siren so I don't piss the neighbors off when it storms?

Thanks

Why don't you just adjust your sensor??

Decreasing the sensitivity to a point where thunder doesn't set it off is the same setting as "Silent while being towed away".

Assuming the siren is standalone and just connected to the control module with two wires, you can just add your switch inline to break the connection when you want it silenced. You just need to decide where you want to locate the switch and run the wires.
If you have some unused aux output from your alarm, you might even wire in a circuit with a relay so that you can silence it remotely, by pulsing it twice in rapid succession or some scheme like that. Toggle switch is simpler, but then you'd have to anticipate the storm and set it manually each time.

On my crimestoppper, when you press the lock button to arm the car, you can then hold the lock and unlock together for like two seconds and it will disable the shock sensor, but still protect the car's doors and starter etc.

You may want to take a look at optional sensors. If you need to set the shock sensor so sensitive that it false alarms all the time then either the sensor is malfuntioning, its improperly mounted or placed, or your expecting too much from a shock sensor. Piezo Electric impact sensors have been recommended many times on the forums. They work by reading the air pressure inside the vehicle by means of a piezo electric diaphram. Any impact on glass or metal creates a sudden change in air pressure and sets the alarm off. These can be hooked up to the pre-warn or the instant trigger. The sensors can be EXTREMELY sensitive so that only a tap of a ball point pen will trigger an alarm. Rain drops, bird poo, will not trigger these. A tilt sensor can be used to prevent theft of rims or to notify of the vehicle being towed. A radar sensor can be used to detect motion inside the vehicle or outside. The draw back of a motion sensor is numerous pre-warn triggers as the sensor detects any motion within a foot of the car.
