I’m just wondering if there is some clever way to detect where a set of lost car keys might be using a phone, radio or even something more techie like a Spectrum Analyzer.
Basically, yes, we’ve gone and managed to lose both sets of car keys! Spent a couple of days searching everywhere we can think of but no luck so far and are pretty sure they aren’t in the car itself as it’s one of those keyless entry systems (2013 Mazda 6) that detects if the key is inside / nearby to let you in and start the car.
Anyone able to point me in the right direction? Getting locks replaced and new keys is going to cost a lot even with insurance so I may as well try a more techy approach first. Unfortunately am not an electronics engineer though.
