Being burgled is a horrible experience; not only have you lost your possessions, but you have probably been left with a mess to clean up and also have the feeling that someone has violated your home.
Ever since we’ve had houses, we have wanted to be able to lock our doors to keep ourselves and our possessions safe. Commercial properties too are a prime target for burglars since thieves know that there will be goods, and perhaps money, as a reward for their efforts. Doors and windows are the obvious way into your property, so they have to have the appropriate locks to make life as difficult as possible for the intruder.
Also, insurance companies have requirements for types of door lock to be used. You don’t want to be in the scenario of having lost your property and then find that your insurance is invalid!
