I locked myself out of my car so often I ended up wedging a coat hanger under the rear bumper. You're right: car doors used to be trivial to yank open when you knew the trick. These days I'd love to create a little side project that sets the alarm off on my car any time a relay attack is detected. I'm sure Mark Rober or someone will end up doing it.
- mulmen 3y agoWouldn't it have been easier to put a second key under there?
- tourmalinetaco 3y agoOf course, but that takes time and money to get a new key made. And once you know the trick it’s trivial using a coat hanger.
- biosboiii 3y agosounds rather complicated. You would have to scan the entire spectrum (not the entire, but like certain bands) and detect if there is someone sending power on there. But modern vehicles detect these relay attacks and drop your message when you are too far away (ToF Measurement), you could maybe instrument that. But then when you walk to your car on an open field, you may also trigger the alarm because your key is out of range for a short time.
- nox101 3y agowhat would the alarm do other the annoy a few hundred people. It wouldn't save your car. car alarms should be banned imo. replace them with something that pings your phone maybe but the alarm does nothing
- neuralRiot 3y agoThere are alarms with phone messsaging, tracking, remote start and disable. Also relay attacks are easy to prevent, just put your smart key inside a faraday bag or remove the battery.
