Our San Antonio home locksmith staff has many years of experience consulting with customers on the best security solution for their home. Often, a good home security solution only involves a relatively inexpensive rekey all the locks in the house. For instance, in many upgraded homes, new high security locks have already been installed. Unfortunately, the new owners can never know who had keys to the house prior to them. In this situation, a rekey of the house -- the most inexpensive option would likely be the best option.
