If you go into most any home improvement store to buy a lock, you will have access to Schlage keys
. They are slightly more expensive than Kwikset, but provide a sturdier physical construction and are harder to pick and bump. The company has a variety of models, but their cheapest is significantly better than the cheapest Kwikset. Cylinders like the Primus and Everest tout a very impressive narrative of anti-bump and pick resistance, but they are pickable and bumpable. The locks that Schlage makes are by far the best low-cost option out there. Much like Kwikset, the amount of people that use this lock is where we see the trust in the brand.
