Why hire me?
I’m the best value, not the lowest price.
I answer the phone, provide the quote and do the work. You deal with me from your first question to the finished job.
I give clear written quotes before work begins, with no hidden fees. I explain what I find, answer your questions and repair existing hardware when a sound repair is possible. I won’t recommend hardware you don’t need.
I’ve lived in Fremont since 1989, been a licensed locksmith since 2008, and run GreenKeys Locksmith since 2010.
