I saw some lady trying to get back into her (as she put it) loaner last night. Apparently the fob had quit working, she had attempted to battery swap and reprogram her own Tesla fob (didn’t know that was user serviceable). There was a pickup truck making circles around the block and a spotter across the street from her crouched down wearing a hoodie.
With the rise in car thefts recently I wouldn’t be surprised if thieves are trying whatever methods they think will work to get into your Tesla. Keep your fob in a faraday pouch, use two factor on your account, and enable pin to drive.
