"Needed a new lock for the kitchen door. Jaime set a time for an estimate. He arrived within the time frame, gave an estimate to include purchasing the new lock. Purchased the lock and installed it. When he finished, he cleaned up very well. Would definitely use him again when I need a handyman."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"It is so important to find an honest, trustworthy locksmith and Alan is definitely the best in the business. He is a total professional and I trust him to re-key my whole house. I have used him on numerous occasions - basically whenever anything goes wrong with my locks- and have recommended him to colleagues and friends. All have had equally positive experiences with both quality of work and price. I would not believe that other reviewer."

"Words cannot express how amazing James is. We have this old lock on our front door that needed to be removed. James offered free guidance to aid my husband and I in removing our old lock. We failed miserably and James came out day of. Throughout the whole experience, he was professional, he was informative, he even took less money from us than quoted. I dreaded getting a locksmith just because I didn’t want to go through the hassle of dealing with a person and getting ripped off. But let me tell you this guy is amazing and I would hire him again in a heartbeat and have already given family members recommendations. 10/10"
