Needed to replace a car key; not a lockout situation. Brad immediately ordered the proper key (didn’t have a Jeep key in stock), called as soon as it arrived, and had the key cut and programmed in about 10 minutes. Very happy to have found such a professional. Highly recommend.

I was just locked out of my house and to be honest, at 11pm on a cold fall night, all I wanted was to get inside. I spoke with Brad on the phone. He gave me different cost options to solve my predicament and did not pressure me one way or the other. Someone was here in less than 10 minutes. The people involved were kind, professional, understanding, and didn’t make me uncomfortable or badly about my situation at all. If anything, I was completely relieved to receive the efficient help. The short duration that it took him to get me inside was well worth the money. The price was completely reasonable considering the time, and I could not be more appreciative. Thank you very much!! Literally cannot go wrong choosing this team, especially in a pinch!!

Called about a missing key for my RV, gave him the lock manufacture and code, which was on the lock, and he provided replacement keys. Both worked the first time. Great service and very friendly!
