My alarm has never given me a problem, but started acting up today. I am swapping in Cobra mirrors into my car and had to disconnect the Mach 460 Tweeter cable as well as the power mirror electronics. Those are the only things I disconnected. After the install and during my alarm did not want to respond to any buttons pressed on the remote. So I went in and grabbed my spare keys and the same thing, the other remote wouldn't work either, so I knew it wasnt the battery. I kept playing with the buttons and finally it responded but then cut out again. I just locked the doors manually and let it sit for awhile, I came back 30 minutes later and the remote worked again, locked the doors no problem as normal. Why do you think it is doing this? I dont want it to keep this up. Everything is plugged back in and nothing is out of place. Also, when the unit does not work, everything else in the car works fine. Doors lock and open manually, car starts, headlights turn on, so its not the car battery. The theft light in the cluster also blinks like normal, so I do not understand what is happening. Thanks for your help!
