Disable loctronics alarm system

I have a 95' mariage that a friend gave to me. They said it was not starting or even trying to turn over and they believe it to be a simple problem with the loctronics. I want to disable it and try to start it to see if that fixes the problem. However I do not know much about the system itself. If anyone has had this problem with their system or knows how to disable the alarm please let me know. Thanks
