Yesterday I had a call from my MIL's carer who was supposed to be taking my MIL shopping to say that my MIL had locked herself out of her flat - yale lock. This is not the first time it has happened and we only had new locks fitted a few months ago because she lost keys and a neighbour prised open her door as she couldn't remember our telephone number. Our problem is that we have spare keys but live a fair distance away, my husband works away at times, and I don't drive as well as having 3 children and the usual school/nursery routine to work around. Yesterday my husband had to drive back home from the office to pick up the keys before going to my MIL's. If it had happened last week we would have had a big problem as my husband was in the States. So we know now we should each have a set of keys but the carer also mentioned having an external box with a combination code outside my MIL's flat to keep another set in for emergencies. She is going to try to get details from her agency for us but I did a search and found this one from Screwfix http://www.screwfix.com/app/sfd/cat/pro.jsp?id=77908 I think we would probably fix it inside the building outside her flat door and rely on one of the neighbours letting someone in through the door buzzer system. Don't fancy having it outside the mainbuilding door. Wondered if anyone has had any experience of these. Don't want to ask any of her neighbours as she really doesn't know them well (only moved there less than 18 months ago) and I feel they already see her as a bit odd. Or any other suggestions gratefully received!
