Can thieves store the frequency of a keyless key to steal your car later?
Even if you have a Faraday bag, can thieves detect the key frequency as you park-up? Then the thieves have the signal stored in their relay device, or does the key have to be active for them to gain entry?

As far as we're aware, no. Our understanding of these devices is that they just extend the signal from the key when it's in range. I don't think the device can store a key's signal.

How do I protect my car key signal from being stolen electronically when my car is parked?
Are there any cars with keyless entry, where the keyless entry facility can be disabled? So I can use a remote fob and press a button to unlock instead. Faraday cages for keys aren't sufficient for me.
