AFTERMARKET CAR ALARM DAMAGES SECURITY MODULE

(1999 Mercury Villager)
Installed aftermarket Viper 350 alarm in car. Worked OK until door was opened when alarm was active. This blew smart entry control module. Headlights stayed on and horn blew.
Removed horn fuse. Removed negative cable to hush headlights.
Instead of door trigger used dome light as trigger for alarm.
Any ideas on what caused alarm to fry our control module
Replaced module since and everything works fine.

I have seen good remote start installers fry modules installing am remote starts and alarms, usually has to do with spiking some type of module with an improper wire hook up or voltage.
