But when it comes to keeping your family and your belongings safe, security is not something that nearly two million citizens forget or take lightly. That protection usually begins with the locks of their house. This is especially important in an area known for high rental rates. In fact, 69 percent of the people are renting rather than owning their own home. This is more than a happy fact: rental properties have higher housing benefits. In short, failing to change your locks regularly (from the building level) means that hundreds of previous employers may have copies of your keys. Then, imagine that each former employer made at least three copies and handed the keys to his friends and family; perhaps even friends of the friends are happy recipients. What was it that once an extra or two hanging key that had not been used on someone’s key holder has become a major virus of sorts? It is enough to strain even the strongest citizens.
