Jim and his team are amazing! I was in a jam and locked out of my house. With a recent power outage I was unable to access the garage to get inside. He was able to quickly get in through our front door with his emergency tools then pull our locks and set us up with a few keys so this never happened again. He was quick to arrive, very knowledgeable and solved our problem. I HIGHLY Recommend NorthStar Lock & Service for Residential and Commercial projects pertaining to Locks, Cameras and Security Systems.
