I work a lot with Realtors on homes to rekey and make secure. If your tired of having good locks drilled out and cheap locks put in their place, call me. It really bothers me to see a $150.00 Baldwin lock drilled open and replaced with garbage. I also can pick open most key boxes that use letter or number dials to open them. My pricing is very competitive and is on my web site. I charge per lock for rekeying, (not per cylinder or key hole) as others charge. A lot of places will charge you twice for one lock because it has two cylinders in it. I give free estimates and can usually tell you how much a job will cost over the phone.
