And to answer the OP's question, yes, the world has gone crazy!

My daughter is 40 years old and has owned cars for years. Her 91 Toyota Celica was recently rear-ended in an intersection by a distracted pick-up driver. The resulting damage was enough for the insurance company to "total" her car. You can imagine what the insurance company paid out for the car. No, I don't doubt her ability to not lose her keys. What I DO doubt is the ability of the manufacturer of any new car and the manufacturer of any of these fancy keys to produce something that will function reliably for as long as the key for our 92, or her 91, has lasted. In fact, I would doubt very much if those fancy keys or the receiving devices in the cars of today are going to reliably last for even HALF as long and even that is probably optimistic. Of course today's 19-year-olds would not only not expect anything to last that long, they probably don't realize that it can, AND SHOULD, be designed to do just that. BTW, what powers those keys - a small nuclear power plant? Please don't tell me it's a battery....please.

ORIGINAL: Tony1M BTW, what powers those keys - a small nuclear power plant? Please don't tell me it's a battery....please. From Wikipedia: Passive RFID tags have no internal power supply. The minute electrical current induced in the antenna by the incoming radio frequency signal provides just enough power for the CMOS integrated circuit in the tag to power up and transmit a response. Most passive tags signal by backscattering the carrier wave from the reader. This means that the antenna has to be designed both to collect power from the incoming signal and also to transmit the outbound backscatter signal.
