JLR Relay Attack Prevention

Relay attacks let thieves amplify your keyless fob's signal to unlock and start the car while your key sits indoors. Here is how they work and how to stop them.
How relay theft works
One thief holds a relay near your house to capture the fob signal; another relays it to the car, which thinks the key is present.
Prevention
Store keys in a Faraday pouch, enable motion-sleep on the fob, and note that newer UWB keys resist relay attacks by measuring true distance.
Which Lock50 Tool Do You Need?
- Programming a UWB key needs the HW04-C+ Tool Kit.
