We called Prelock to change our locks when we moved into our new home. They were prompt, professional and helpful. They made excellent recommendations for our needs, which included two sets of keys and locks, for our side door, which is also used by a tenant, and our front door. They also advised us which doors and windows in our home were secure and which could use upgrading, without pressuring us to do anything extreme. They provided some options and solutions for keys and locks that were workable and simple. The service was great, their staff was professional, and we were very pleased with the job done.
