What Our Customers Say

Rated 4.8 stars with 95+ Google reviews, National Lock & Key consistently earns praise for professionalism, speed, and value.

Tracey Bisbee ⭐⭐⭐⭐⭐
"Outstanding service. My spare key fob broke after dropping it and the key with broken FOB wouldn't start my car. My car was stranded at the airport parking garage. Called these guys and arrange time to meet me at airport parking garage. Price was cheaper versus what the dealership wanted by $150. Only took 20 mins. to cut new key, perform multiple tests on outside door lock and ignition switch to confirm fitness and no issues inserting/removing/turning key and reprogramming new key FOB buttons, and test new key FOB security buttons — Perfect, worked like a charm. I highly recommend National Lock & Key."
