My car lost its GPS, cellular data, and Wi-Fi last Tuesday. I spoke to someone in Volvo service on Friday afternoon. He advised me to do a hard reboot- pull the power cord from the 12v battery under the hood. The battery is pretty easy to access. Those split rivets are genius. There are four wires hooked up to the distribution block on the positive terminal. I started with the fattest gauge wire, figuring it was the most important. As soon as I pulled it off the anti-theft alarm was triggered. It is ----ing loud, especially in a closed garage. The panic button alarm is tame- just the horn and lights. The anti-theft alarm is end-of-the-world loud, especially when you have your head under the hood. If you aren't expecting it you'll hit your head on the underside of the hood. Just something to keep in mind.
Unfortunately, that wasn't the right wire, or it was and it didn't help. The infotainment panel didn't turn off when it was pulled. I tried to disconnect the three smaller positive cables but their bolts are stuck. There's obviously green locktite on them. Now, I'm not Hafþór strong, but I'm decently capable and can apply some torque. It felt like the distribution block was going to shear from the battery before those bolts were going to give way and I need to drive this car to get the kids to school so.. I gave up, put the panels back in place, and quit for the day.
The Interior Movement Sensor monitors the interior of the vehicle with ultrasonic waves. If it senses movement or unauthorized entry, it can activate the vehicle alarm, which will trigger the horn, siren and vehicle lights as well as the Surround Vision Recorder, if equipped.
The Shielded, Battery-Backed Alarm Siren offers a dedicated siren, mounted in a secure location with its own power source to help protect the vehicle against break-ins. The system is designed to sense an abrupt loss of signal from the Body Control Module and sound the alarm. When on, the alarm will sound the siren in three instances:
Yes. To disable the Inclination and Interior Movement Sensors, with the vehicle turned off, press the ALARM DISABLE button. The button looks like a vehicle with a line drawn through it and can typically be found on the overhead console. The indicator light will come on momentarily, indicating that these sensors have been disabled for the next alarm system-arming cycle.
Vehicle Inclination Sensor
The Vehicle Inclination Sensor helps protect against wheel and vehicle theft by sensing situations in which the tilt of the vehicle changes, such as when it is jacked up or being towed.
Occasionally, you can experience problems with PATS which cause the alarm to go off and prevent you from starting your truck. Sometimes, a loud bang such as a firework or thunderclap can set off the alarm. Even somebody accidentally bumping into your truck can trigger the system.
If the battery in your transponder key is getting low, the alarm can start to go off randomly. If that happens, try using your spare coded key. If the problem stops, you know that you need to replace the battery in your primary key fob.
Additionally, check under the door handle where someone might try to force a screwdriver through to open the locked door. If this area is damaged, it could be causing the alarm to go off. If the door lock cylinder or door handle looks damaged, contact your Ford dealer to have them replaced.
You can be confident that you can drive your Ford F-150 without any problems occurring.

I decided to try doing a bit more digging as I had very little actual actual evidence that there was any battery in the siren at all and I was too lazy to pull out the siren at this point without any proof. Looking up the Anti-Theft Device page for the Lexus IS on japan-parts.eu was quite fruitful:
I had absolutely zero luck finding 7.2V 2/3 AAA batteries, all the 2/3 AAA listings are for single cells or 3.6V batteries. It looks like these 3.6V batteries are often used in cordless phones. For those unfamiliar with batteries, a 7.2V battery is really just the same as two 3.6V batteries slapped together. Some soldering or wire crimping will be required, along with salvaging the connector from the original battery. The two 3.6V batteries will be wired in series (one black wire to one red) and the original connector to the remaining wires according to colour.
It should be noted that the JDM Toyota Altezza does not come with an alarm at all, no matter the spec or trim. You can verify this when looking at the Electrical page on japan-parts.eu, there is no Anti-Theft Device page. Also the keyless entry remote has the distinct two buttons on the side as opposed to the three buttons on the face of the remote for the IS.
Bike thieves beware! Replacement Alarm for HyperScorpion and HyperScrambler 2 models but compatible with all Juiced Bike models. Comes with replaceable batteries to prevent theft even on an empty battery.
Remember that this is the state where the vehicle is on but the engine is off. All the necessary components like the radio and dashboard lights will be powered up, which makes it possible to bypass the theft alarm.
Then, turn it again to the unlock position and the alarm of the anti-theft system is likely to be disabled now. Run the car for at least 10 minutes after cranking the engine to allow the car to reset the alarm.
Reconnect it and make sure that both the anode and cathode terminals are tightly attached. It will reset the computer system and your car is likely to kick off. In case the trick fails, reset the factory alarm by activating its built-in kill switch.
Trouble starting, lack of ignition power, and unjustified alarms and flashing lights are all common warning signs. These issues might arise if a system was not installed by an expert with extensive electrical understanding of your car.
Note: The Nest Cam (battery), Nest Doorbell (battery), and the Nest Doorbell 2nd gen (wired) includes up to one hour recorded video for on device storage that is only used as a backup if the camera can't upload video to the cloud (for instance, if it can't connect to Wi-Fi).
