Have you checked your garage for small, quiet, quick intruders? Take a sack of flour and the next time you get out of the car, lock it. Then take the bag of flour and spread it on the floor around the car, being carefull not to step into the flour as you exit the garage. Then when you hear the car alarm going off, simply yell loudly to scare the intruder off, and go out and look for footprints in the flour. Make sure you can recognize your footprints - perhaps carve your initials in the bottom of your shoes or in your feet if you are not wearing shoes. Well, don't carve the initials toooo deep in your feet. Of course then the blood would be easily recognizable so maybe you only need to put a couple of pin pokes into your feet if you are barefoot. And do be carefull to only use real American flour that you have paid full price for in a regular store. Some of those dollar stores are carrying counterfit foreign flour with all sorts of dangerous chemicals and germs in it. But if your theif is barefooted, it might be better to use the foreign counterfit flour since he or she might get sick and die. Of course if you have a spare glass, you could break it and spread the glass around the car, but not behind it or in front of it and that way the intruder would be more likely to cut their feet and contract a deadly disease from the the counterfit flour. And the flour will help hide the glass from the intruder. If you don't find any footprints, then it is possible that you didn't really have an intruder trying to steal your car. Or they could have been hiding in the car in the back seat behind you and they just got out and climbed on top of the car and jumped out of the garage. So maybe you should buy a second bag of flour and spread it on top of the car also. Or you could just check for unlocked doors of opened windows. When you have done all this in carefull detail, you may be assured that you have eliminated the most likely cause of car alarm malfunction today, the sneaky intruder trying to steal it. And that would leave it as a malfunction of the car. But as we all know, these cars are perfect and do not malfunction, so in this case you may assume you are going deaf and hearing ringing or honking noises. So then you should be carefull to go to the car and get in it and drive carefully to the nearest doctor to get your hearing checked. Which is probably the reason for Ray's question about having the keys in your pocket at home - he simply wants to make sure you are ready to drive off and find medical assistance because he has worked on these and knows they do not break.
