And while I am on a rant, how many times have you been woken up by a neighbor's car horn tooting when they use the remote to lock or unlock? You can program them to NOT blow the horn, but to flash the lights or simply do nothing. I am always standing next to the car when I lock, so I can hear the click as the locks lock. I see no need to add to noise pollution and annoy people. Thank you, stepping off my soapbox now...
