DIAMOND LOCKSMITH REVIEWS

This guy has helped me twice since I moved to California. The first time he was so accommodating with where and when to meet. The second time I met him at his office as he was on his way to the airport to fly out of town!! The absolute best customer service!.

Way to start a Saturday with car key locked inside. Thanks to Diamond Locksmith everything got set straight in minutes for a reasonable price. Very professional and highly recommended.

Rescued me when I locked my keys (and phone and computer) in my car in my office parking lot. Arrived and had me on my way in 30 min. Reasonable fee. Super nice guys.

SAN MATEO LOCK WORKS REVIEWS

Best most friendly service ever! Great value and super fast. The folks working were knowledgeable and it was great to support a local mom and pop shop instead of the Home Depot that had both key duplication machines out of order. Mom and Pop is the way to go! Thank you so much.

Another perfect visit. Even when they cannot solve your problem right away, San Mateo Lock Works is always able to take the time to suggest multiple options for my issue. I personally have loved this shop since 1997 when I moved to the SF Bay area.

Roberto and Eric helped me get some keys sorted. 4 other places couldn’t do it….. and they did it under 5 mins. Great knowledge and skill. Thanks guys.

LOCKWORKS UNLIMITED, INC. REVIEWS

My motorcycle dealership dropped the ball and never printed the track on my new key. I was stuck and about to lose my mind. Thankfully, Lockworks Unlimited came to my rescue. They are incredibly professional and clearly have the best technicians in town for handling even the most complicated foreign keys. They quickly resolved my issue and got me back on the road. I'm incredibly grateful for all the keys they've made for me over the years! Highly recommend.

Highly recommended! Easy to set up same day appointment ... my locksmith Jorge was right on time (they give you a time window)... quickly replaced the lock for which we had lost the keys... after he had installed it (it was an old door) he made sure that the new lock worked perfectly with the old door... even switching out another piece to ensure smooth opening and closing. Jorge was super friendly and really knew what he was doing. Price was exactly as quoted.

These guys have been in business in Redwood City for over 30 years and they're extremely knowledgeable about keys and blocks systems. Prices are great. Overall, fast, reliable the only place I go to.
