Is my Factory Alarm System working?
 

2019 Camry LE with factory installed intrusion alarm that goes off whenever the car sits in the hot sun for a period of time. Toyota replaced the battery but that didn't solve the problem. Now they have replaced the driver's side door sensor and the issue is apparently resolved. I now want to test the alarm to see if it trips as designed. What steps do I take test the functionality of the system?

Try locking doors with FOB and then opening a door with key.

When inside the car lock doors. Unlock hood and have someone open it.

Lock car and tap on window. The alarm may have a glass breakage sensor. Rock chassis as it may have tilt sensor.

Have FOB or key handy to silence alarm.

The bubble on the dash is the headlight sensor that turns them on when it gets dark.
