I hired them to change some Door & Window locks to make my home safer. They used quality material and offered various options. Two of their Technicians Steve and Christian did the work. Super nice, clean cut and all around a pleasure to work with. I think their pricing was average but I only got two quotes and theirs was similar to the other company that seemed a little shady and these guys have been in Denville for decades.

I have been a property manager for the last 15 years and they are the best locksmith and security company out there. They have re-keyed thousands of tenant spaces for me, installed access card readers, handicap door openers, etc. They do it all and also they also respond to service calls on the same day. I highly recommend.

Made an appointment to have the locks changed in our new location in Clifton. The men were on time, neat, respectful and pleasant. I was made aware of an issue we hadn't noticed that would make a serious breach in security & was able to correct it with their recommendations. We absolutely would call them again for any locksmith or door work we may need.
