It works fine for a few days then it just randomly won't start and when I turn the key over I hear a single clicking noise in the rear fuse box but it won't crank theres also a light on the display that says service theft system ive had the car for 3 years with not a single problem till I hit a pothole and threw out my rear shock tower I don't know if I knocked something loose back there or what but if replaced the battery cleaned the grounds and I've banged on the starter and it still just clicks at the fuse box please any bit of advice helps

If there is an issue with the security system it will not let the engine crank at all. You'll need a proper scan tool to determine the issue with the security system.
