Robots can give you (hopefully working) keys but they don't remind you to lub your exterior locks and not to use wd forty as lub ('cayse it ain't lub). Nice shop, vast knowledge base, priceless!

I had 3 copies made for a file cabinet. The service was super fast for high quality duplicate keys for a great price. I also conveniently picked up some accessories for the keys. Fantastic customer service and they are VERY knowledgeable and gave excellent advice. All the keys worked perfectly! Highly recommend Foster Brothers!

Super fast turnaround time and high quality. They charge less than stupid key-copying machine, who made a key copy that doesn’t work and I have no where to complain about… Foster brother did me a favor to fix the non-functional key copy made by machine earlier. Highly recommend this store!
