How do I know if my key is keyless?
If you can unlock your car by touching the door handle and start it with a push button while the key stays in your pocket or bag, you have a keyless (proximity) key, the type relay attacks target.
Which cars are vulnerable to relay attacks?
Any car with a keyless (proximity) entry key and push-button start can be targeted, whatever the brand. In ADAC testing, about 9 in 10 keyless models could be opened with a relay attack; keys using ultra-wideband (UWB) technology resisted the attack.
Does the case work with my car?
Yes. The case blocks the key fob's own signal, so it works regardless of your car's make or model.
How do I test that the case blocks the signal?
Put your key in the case and close it, walk up to your car and pull the door handle. If it stays locked, the signal is blocked. Open the case and the car unlocks again.
