my issue with my dad has gotten worse,today before 330 my girl said he was in our home 5 times,its come to the point I have to prevent him from entering all my buildings,im extremely worried my shop could be burned down,as well as my barn.we live close together,within walking distance.i think I can use the open bar holder type that hold a 2 by 4 on all the doors but 1 in each building.i am refusing to use a keyed lock,a few of my closest friends have a key for my shop,and dad will con them into letting him in.so im thinking of a power keyless lock with a code that only my imediant family will know.i am a diabetic and needed a a few emt calls over the years,so im thinking I can notify the local 911 of the code,of they must call a family member for the code.does this sound like a good idea ??...girl just called,make that six times today,i hate to be an a-hole but my family needs some privacy,or I have to sell and move away......
