Mine is in garage, up and over door with extra padlock(no cost as already had angle&padlock) at top on metal angle bolted to door&door frame at all times, if away from home door is also clamped on bottom of door with bracket (no cost as already had metal ect+ padlock)that bolts into threaded sleeve into concrete, drive to garage has 2no. Fixed bollards (£60ea)+ 1no. Bollard that drops down(£200, straight down type, lay down ones are not so secure) + steering wheel disc lock(£100). Plus another car parked in front of garage when we are there. When away from home always take keys / hide um up, which sometimes is a pain as when I get back I have before forgot where I hid them , a mate left his motor bikes at mine for 6 months and as normal I hid the keys up, when he wanted to pick um back up it took me weeks to find the fucking keys🤣
Security is generally something to deter the scum to pick on something Easyier and at worst slow um down.
Just put yourself in the scum mindset with what would deter them.
