Anti theft - ramble - discussion / suggestions?

[chl]

1, yes
2, probably
3, dependent on the objective of the thief
4, haven't seen one in forever
5, sure, but then the truck wouldn't respond
6, faraday cage
7, theoretically possible with a flipper zero

3. Well all the parts are worth stealing, seems to happen a lot in some areas, esp. rear/tail lights and even tailgates.
5. The FOB signals are already encrypted...however...they still have...

Common vulnerabilities

• Replay attacks: Thieves can record the signal from a single use and "replay" it to the car later to gain access.
• Relay attacks: A more sophisticated method where a thief uses a device to capture the signal from the fob, even if it is in the owner's pocket, and another device near the car to "relay" the signal, tricking the car into thinking the fob is right next to it.
• Weak encryption: Some older or less sophisticated systems may have encryption that can be broken with enough effort or specific tools

6. An inexpensive solution is aluminum foil folded into a pouch to put the FOB in - yes works just as well as a fancy dancy pricey commercial Faraday cage...

I use it in all my hats to keep the brain police from reading my mind or giving me a brain tumor! (not really but thought about it, lol)

All the responses about shielding the FOB do not address the issue of when the FOB is given to a dealer or repair technician: I get it - we can do a "cage" to prevent theft of the FOB electronics, but that does not address giving the FOB to a repair man - whats the solution for the FOB in anonymous' hands???.

Trust your dealer?

Valet key for others.
