Funny story, back in college drinking with my roommate I got it in my head that a beer bottle must be designed to withstand a 6 foot drop on the kitchen linoleum floor. Being an Engineering major it sounded logical at the time, my roommate doubted me (as he should). So I showed him twice and both times the full bottle of beer survived. Then he tried it with his next beer, that didn't work out so well, turns out I was wrong, lol.Keyfobs are designed to be able to withstand a standard drop test, at least, which is 6' onto cement. That being said, anything can happen. I'd think i'd just go on with my life knowing the engineers took this happenstance into consideration when designing the fob.
Sure there's moving parts in them. What to you think happens when you press the button? A piece of plastic flexes, which allows it to push a harder material inside a rubber membrane below the button, which in turn presses a microswitch on the circuit board of the fob.There are no moving parts in the keyfob, and it might seem crazy, but the days where you knock on some electronics to get it working again after it failing are long gone. The only possible reason why banging an electronic fixes it is there are multiple PCB boards connected together via a plug or slot of some kind and it might come loose, otherwise, if it's a single PCB board and everything is soldered properly, it will most likely be fine, the reason I say most likely is there's always a chance that you actually breaking a component by banging on it too hard. But in whatever case, if it works after the drop, it'll keep working (till the battery runs out or some other accident it might go through).
That doesn't count as moving parts... moving parts means it will move on it's own, i.e. motor of some kind. Anything will be a moving part if you say the micro switch is a moving part.Sure there's moving parts in them. What to you think happens when you press the button?

Ask me how I know (my son threw sand on me at the beach, which happened to get lots of sand in the fob that was in my pocket, and jammed it up...fortunately my wife was there with us, so I could use her fob until I could get home and disassemble/clean my fob... :frusty
