Just about any alarm can activate your double locking feature. What is needed is a +12V pulse at both lock and unlock inputs to the power doorlock system. You or your installer would have to install a diode at the (alarm of your choice) wiring harness between the lock and unlock wires. When you arm the system, both inputs gets a positive pulse and double lock happens. When you disarm, only the unlock gets the pulse. Also, check into the ignition controlled lock feature. This locks the doors when your start the car. A safety feature is that the double lock does not work when the ignition is on. Good luck.
