Had call out this morning to home that had a break in while they where in bed Apparently The thiefs manage to open there front door when They were sleeping and taken car keys and cash.This is becoming big problem in Edinburgh.the standard night latch is not a secure lock and is very easy to open if you know how.the tenant could not under stand how They got in. So i showed them how easy it was to open there door just with my tools . and he could not believe how quick i got in.with out any noise. i fitted a security Yale lock .then i showed them the difference on how to get past this lock .much more difficult .so have look on this site and don t let criminals get away with this .especially this time of year. call anytime even if its just to get a bit of advice about your locks and security at home.
