Sean was prompt and super knowledgeable. The lock on my front door is over 70 years old. I was afraid it was going to be an expensive repair. Sean dismounted the entire handle, took it to his repair van right on site and disassembled--and then rebuilt the entire mechanism. He mounted it back in the front door and it looks better than new. And the lock works beautifully! Plus, he gave me four new keys to go with the rekeyed lock. Perfect! Plus, I had him look at my garage door lock that has been stuck forever and in 10 minutes he had it working perfectly. Great work. I highly recommend Down Under.
