Alright I just bought a 1988 RX7 and I knew that it had a security system but didnt know how to work it. So one day i was at work and locked both doors and then after work i came out and was in the process of unlocking it and the alarm started going off. I got into the car and thought it would go off after i started the car, but it didnt. It wouldnt let me even turn then key. Finally i unhooked the battery and hooked it back up. So can someone please tell me if there is a switch anywhere or where I can get a replacement thing to turn off the alarm. Thanks a lot.
