I brought a second hard car about two years before. It has an automobile alarm security system came it. Three months ago, the car couldn't start. We sent it to the auto repair store. The car could start; the store said the security system locked the car, and he had no ideas how he fixed it. Also, he had no ideas how to remove the auto alarm. Now, my car can't start again. I need help, and I want to remove the security system. Please! All I know is the FCC ID: ELVAT5C.
