Factory Alarm Not Working After New Stereo Install
Okay, got a 99 M Coupe with the factory alarm and keyless entry system. I upgraded the stereo to something way nicer than stock. After I did so the keyless entry stopped working (I have not checked that the alarm still goes).
Used to be, you'd hit the [Lock] button on the key fob, there'd be one beep from the car and the doors would lock. Hit the [Unlock[, get two beeps, everything unlocks.
Now, if I hit either button, I get three beeps and nothing happens.
I suspect, since the factory head unit is wired into the alarm system, it's freaking out because the deck is gone now so it's disabled the keyless entry to let me know that someone stole my deck (in its thinking).
Any suggestions on how to fix this without having to go buy a whole new alarm? Or if I do have to buy a whole new alarm, I've heard it's pretty easy to just replace the original unit, any suggestions on that?
