Haha I wish I could easily find one without the alarm because I hate mine. It's got some weird quirk where every once in a while when you start it, the alarm will suddenly go off, so you gotta turn off the motor, press lock, unlock and then start it again and it will stop. Just does it once and then won't do it again for a week or so. Just weird, hell maybe it's because of this wacky bcm in there now.
