Changed oil today and finished up. Closed door, pressed lock button on FOB, no chirp, and LED door light was solid for about 5 seconds then started blinking. I have been having issues with siren, and bought new one and installed, thinking this was the issue, but after installation, same - no chirp, solid LED. Pressed the panic button on FOB, no alarm.

I am pretty sure that a solid LED mean that a door or hatch is not properly closed, so double checked both doors, engine lid, frunk - all are closed.

Also, regarding alarm, when you are sitting in the car with it off, there is a way to turn off the alarm so it does not go off. I may have done that by mistake. How to turn it back on (if that is what I did)

Any ideas?

SOLVED.

But not sure I know how. As mentioned, both old and new siren did not work. I disconnected battery for 20 minutes to reset everything. With new siren in, still the same - no chirp. Put the old siren back in and now back to chirping! I think I know what happened. I used Thinkdiag to change coding for doors to remain locked when I open frunk. When I opened frunk for an extended period of time to change out siren (doors remained locked), I think system got confused. Disconnecting battery reset everything. Not sure that is the cause, but just the same, time to use Thinkdiag to change door/frunk locks to the way it was.
