Remote would not open door car would not start
Okay I've read through several threads on this , but doesn't seem to be a definitive answer. I drove my car , everything was normal. Came back a couple hours later, pushed the remote nothing. Unlocked driver door with key, alarm went off. Got in the car , attempted to start it, nothing. Engine did not turn over , dash lights up. Removed fuse 9 alarm goes off. Disconnect battery for several minutes, reconnect. Remote still doesn't work . Open door with key, no alarm. Put key in ignition, car starts. Drive home. Light on tow switch blinking red the whole time. Get home, turn off car. Put fuse 9 back in. Remote works as normal. Can lock and unlock car and start car. Obviously the alarm and anti theft system was activated and I couldn't shut it off, so the car wouldn't start. I thought when you open the car door with the key that it turns off the alarm system ? I checked the remote batteries and they're good. Car battery seems good ,12.6v ,as well as ground. Alternator putting out 14.2 v .I'm a little confused where to start trouble shooting. Is this the Skreem, the remote receiver in dome light assembly, or just a fluke?
