did 2001 RX300's (and GS300's)factory alarm system
have glass breakage sensor?

for example, if someone breaks the door
window with a fist(or a hammer), is the
alarm supposed to start honking?

Thanks!

P.S. please don't ask me why I'm asking about glass breakage on both GS300 and RX300...

No to glass break
No to shaking/motion.

Glass breakage sensors are prone to trigger false alarms, thus are seldom found on OEM systems. My home is about a mile from the end of a major runway and passing aircraft used to set off my glass breakage alarms until I had them disabled. Loud exhausts, or any sharp, percussive noises tend to make your alarm more nuisance than protection - and will soon desensitize your neighbors to the extent that they ignore it when activated.

Yes it has glass breakage sensor. If a glass breaks you can see cracks
Actually it is almost imposible to break tempered glass with an average hammer, you will beleive me only if you try it. I have seen a girl doing it to her boyfriend's car in Houston. She hit the glass 20-30 times but did not break it. The easiest way to break it is to smash it with used spark plugs. Are you in New York or something?

Last time I tried to break a car window was on my new '67 Mustang. I locked the keys in the car during a fight with my financee and wanted to leave ASAP. Grabbed a brick to smash a vent window and after three mighty swings, broke the brick. (Finally got in by pulling the dipstick and bending it to fish the door lock). It takes a heckuva wallop to break safety glass - unless you strike it with something very hard and sharp. A punch works nicely. I've heard that "ninja rocks" work too - but don't think I'll try . . .

Wow.

I never thought about that in using the tranny dipstick to fetch the lock. Good idea.
