locksmith kingston upon thames service. I have two smart locks, one is indoor, a simple eurolock with a fingerprint sensor - working well enough, and the other one is the entrance door, its a massive lock with tree ways to open, fingerprint, 4 to 16 digit lock and a card lock. I've spend a lot of time searching for the best one for my entrance door, and to be honest first couple of weeks I was a little bit nervous but the calming factor was the integration program with my phone, so you can see if there was a door opening or somebody tried to enter your home and couldn't manage it. One of the best things about card lock is you can assign multiple cards for your lock and every one can be personalized for a particular person, with an ID or with a whole profile with a photo and ID data. As far as I was told this kind of locks are pretty hard to broke and it will take you a lot of time to hack this lock so I am pretty sure my home is safe now
