Whole point is to deter though, to prevent it happening in the first place. Ghost only works once they’ve found a way in to your car which is normally by going through your door for the keys or smashing a window both of which come with repair bills! I got my Disklok off gumtree brand new £70 with all 3 spare keys - try gumtree or ebay
If they are willing to do that,they would be willing to do the same and force entry for the key to the disklok though.
I can’t see anyone ever trying to grind it off so they know it needs a key.
next decision is get in House and find key
if they can’t find it threaten the occupants
ultimately I would say same outcome
thing is if they are ready to burgle you’re house they are organised and not just someone looking to smash and grab.
it will be car for order or to use in a bigger crime and therefore the car is required and if they choose yours they choose yours.
I have deterrents on my house with cameras and alarm so hopefully that is enough,if they get keys and it don’t start then hopefully there would be no damage and they give up.
I guess it’s a lot of what ifs and best solution is to have it all
