Most of the Fiat 500 thefts are keyless entry clones is my understanding, relatively easy unfortunately. Lots of similar stories on the Abarth owner forums.
That an a Thatcham steering lock. Faraday cage for key, lol. God knows if someone managed to scan and clone this key, seems wildly opportunistic as it was parked mpre than 100m from the house. Guessing there’s some generic clone that can be downloaded
The other theft method is to plug in directly to the OBD port, so people use dummy or OBD locks for this. Like has been said, all the standard anti theft gear, steering locks, alarm, immobilisers. Even the Abarths came with no more than door locks as standard.
