Not sure if once exists, but there's a few times I walk away from the bike after I park, turn the bike off, take off the gloves and helmet, and forget to pull the keys out of the ignition and take them with me. I always remember last second, but worry there's a chance I won't remember. I was wondering if there was any type of device that could beep if I walk too far away from it to alert me and remind me that I'm leaving my keys behind. I saw a Samsung Galaxy Smarttag today I looked into, thinking that might do it, only to find out it's just a locator if I loose the keys (which incedentally, gave me an alternate idea, if I buy something like that, and hide it somewhere in my fairings, would it work if someone steals the bike?). I also don't know how something like this could work if I'm at home, hang my keys up, and walk away without it beeping or something. I imagine it's an app you could turn on and off, but I'm not likely to always remember to turn it on. In any case, anyone have any advice?
