Emily was fantastic! I messaged her and got a response within minutes, and she was at our location within the hour. She quickly got us into a room we were locked out of and was even able to make new keys for the lock right there on site. She also went above and beyond and helped us reset a keypad lock that we didn't have the code for. Emily was quick, friendly, affordable, incredibly kind, and made the whole process so easy. I would absolutely recommend her and will definitely call her again if we need a locksmith! read more

Emily and I arranged that she would repair our door locks on the next day. However as I became ill she dealt with my wife instead of myself. My wife later told me that Emily was very capable and very effective. In future for other lock issues we will definitely contact Emily. read more

I highly recommend Delta Lock & Key. Emily just left my house after installing a new keypad lock to my front door. Before she replaced the new lock, she spent time to troubleshoot the old lock just in case the problem we had was fixable. She is professional, efficient and very pleasant. Price is very reasonable. We are extremely satisfied! I will surely call her the next time we need a locksmith. read more

Outstanding locksmith service--excellent communication, prompt, and incredibly efficient. We needed access to an electronic safe that a tenant had locked us out of. The owner took the time to walk us through a detailed plan over the phone, and on the day of the appointment, she was able to open the safe within minutes. She is not only exceptionally knowledgeable in her trade but also very kind and generous. I highly recommend this company for all your locksmith needs. Thank you so much, Delta Lock & Key! read more

Emily has helped me before a few years back with a defective door lock and it was such a great experience that I reached out to her again today. I needed to get multiple key copies for my house and mail key. She was fast about it, we tested the keys, and at the end she wouldn't take any money. Thank you so much Emily, you're amazing. read more

Emily was a lifesaver! I'm a realtor and had recently closed a deal in Antioch when one of the patio doors with a complicated mortise lock stopped working properly. Out of the four locksmiths I contacted, she was the only one who actually listened to what I needed without charging an arm and a leg. She was knowledgeable, professional, and most importantly, honest. I'll definitely be using her again in the future and highly recommend her to anyone looking for a reliable locksmith in her service area. read more

This is the second and definitely not the last time I use Emily at Delta Lock and Key. Needed 4 locks rekeyed after a fairly complicated family situation.

Super prompt! 4am I sent out a request on a Saturday morning. Emily IMMEDIATELY responded-WOW! =) My security door to my backyard lock mechanism broke. I was hoping for a Monday afternoon appt. She was able to come on a Sunday at 430pm-ANOTHER POSITIVE =). Then price-she is MUCH lower than other locksmiths. So yeah-will contact again. Thanks Emily. Peace. Kris read more

Super fast and great to work with. We needed locks changed at a house we just bought. the locks we bought it with were super old and semi-functional. She replaced all the locks within an hour or so. Gave me options before doing anything. Very friendly and easy to work with and the new locks look great! Definitely recommend! read more

Our front door suddenly stopped working and the latch would not pull back when turning the knob. I thought for sure we would need to replace the knob and rekey everything. Thankfully, Emily came out and said, she could repair it by replacing a part from the mechanism. Emily professional and honest throughout the process. She saved us money by salvaging our existing door lock, giving us a functional temporary solution until the full repair could be made. This meant we didn't have to spend money on rekeying all of our locks. read more

Awesome service pricing was the best I could find. Owner does her own work which I like that means it's gonna get done right. Highly recommend keeping this one on speed dial for my needs. read more

********** SHE'S A GAWD ********* I arrived home couldn't get into my house. I randomly called a few Yelp locksmiths a few brief fone conversations left me feeling exploited. It never surprises me when anyone tries to capitalize on an emergency situation. Listen to this, I called Delta Lock and Key. On the other end of the phone was GAWD. SHE said "I'll be there in 15 mins" without hesitation. How she drove from Discovery Bay to Brentwood in 15 mins IDK. What I did know GAWD was on HER way. I wasn't even given time to explain the problem. GAWD was on her way!! Just like she said 15 mins later she pulled up to my driveway. EMILY is an amazing GAWD!! The BEST service I have ever received, seriously. SHE'S A BAD ASS!! She went over and beyond what I needed she didn't fandangle. She made me feel protected, safe and secure, Emily is a GAWD. She provided EXCEPTIONAL service. She worked in the dark with limited lighting and in the freezing cold. She took her time didn't rush and didn't cut corners. She is very professional , knowledgeable and the most amazing is she sincerely cares about her customer. I will never forget this experience and will share the story of randomly calling a business and GAWD answered my prayers. Thank you, Emily. (tears) SUPPORT WOMEN BUSINESSES read more

I cannot recommend Emily enough! I moved into a new home and wanted my house Rekeyed. I needed 10 locks including deadbolts rekeyed. On a random night at around 10pm, I started looking around on Yelp and requested a quote. Emily responded within 10 mins, gave me a quote and we scheduled an appointment the next day. She rekeyed my entire house and made me 4 keys within 1 hour of being there. She was on time and made sure to text/call when she was on her way. 10/10 service and her pricing is affordable AND reasonable. read more

Oh my gosh. She is amazing. I apologize for not catching the owner's name but I will use Delta Lock and Key forever now. My family member lost a key and she was out at our home in 30 minutes and re-keyed the house. And was super nice. Women owned. Thank you! read more

Called Emily at Delta Lock & Key as I had an older Lane storage chest with no key. It had not been open since my family member passed some years ago. Emily came out a short time later & opened it with no damage to the lock or chest. She also recommended a website to get a replacement key. While she was there I asked her to give me a price on rekeying several locks to minimize the number of keys. She said she could do it now. She was able to rekey 5 locks & replace a deadbolt & one key now fits all locks. This is the second time I have called Delta Lock & Key for service and was compelled to write another Yelp review. Emily does great work & her fees are very reasonable. I highly recommend her for your locksmith needs. read more

We had a file cabinet lock problem and called Delta Lock & Key this morning and Emily was here in about half an hour. She kept at the problem and came up with a great solution which resolved our problem. What a great worker with obvious experience in the business. We could not recommend Emily more for the work she did above and beyond. A great locksmith and person. We will certainly use her again should the need arise. Great value for your buck. read more

Service was great! Installed a keypad lock in the main door and Emily was very friendly, fast to provide the service and the value was good as well. I would definitely call her again for additional things at the house. read more

What a great experience. The door latch on our front door wasn't locking properly so we decided to call Delta Lock & Key because they had such great reviews. The technician showed up right on time and went right to work. She discovered the strike plate wasn't positioned properly along with problems with the lock itself and with our approval made all the repairs including moving the strike plate. We liked her work so much we decided to have her rekey every door in the house, something we had been meaning to do for a long time, and she also made us several new keys for the family. The final cost was extremely reasonable, so much so that I wish we'd had more for her to do. Great job, reasonably priced, and a wonderful personality to go along with it!! I can't recommend this business enough! read more

Emily responded quickly to call, then came to property promptly. She rekeyed the doors and offered good recommendations to secure the house. Emily provided excellent service. read more

Emily is amazing. She is not has reasonable prices (lowest in town) but that's just the START. She is personable, flexible, came back the 2nd time since I didn't have the things ready to setup the smart lock... extra charges for an additional trip -- Zilch.... On top of that, I was like, can you help with the mailbox and she said just made it happened and didn't charge additional service fee for it..: I forgot to mention that when I called over the weekend, late night, she not only accommodated the urgency and was right on the job the next day morning. Yup, she is the real deal (I wish I didn't write this review and keep her as a secret, selfish me... but, she really deserves being the one and only to to person). Thanks Emily, keep up the great work. read more
