There will be a project car in the garage and my regular car will be right up to the door and that's got all sorts of security devices on it (plus it's a very noisy V8) and I'll get one of these to secure the doorhttps://www.lockmonster.co.uk/item/gara ... oCaKPw_wcB
Alarms are a bit pointless, no one ever takes any notice other than moaning about "that bloody noise down the road"
A couple of these ground anchors would be goodhttp://www.tredz.co.uk/.Kryptonite-Stro ... ing&gclid=CjwKEAjwtbPGBRDhoLaqn6HknWsSJABR-o5sQUhijDwnqvAVcvGDxdxV8u7h29SwmT-A-ygY54ZaQxoC_Ozw_wcB
@sandyballs that master lock doesn't look very sturdy in my opinion. In the case of your ground anchor they would attack that rather than the chain, whereas I'd have my ground anchor and your chain that would force them to attack frame. Which hopefully would be a longer process and enabling the homeowner to react
