10/10; would highly recommend!…read more I hired the Danny Keys team when I moved into a new house and needed locks changed. Initial contact: They were extremely responsive when I reached out and I loved being able to schedule online (and there was a solid amount of availability. At the appointment: When it came time for the appointment, the technician (who was on time and fully communicative) went above and beyond in the best way. Not only did the technician answer my 100 questions and concerns about smart locks, but he also advised me my options with different locks throughout the property to balance safety and cost. I thought they would only replace the locks but they also were able to replace the doornobs, offering several appealing options in the style I wanted. They had a variety of options for locks too - regular door locks, deadbolts, and smart lock varieties. They even cleaned off the door all around the doornob because it was dirty and looked a little gross! My biggest joy has to be that they were able to use the same locks on multiple doors so we could use one key for all the doors, which is a lifesaver because I was startingbri appear as a janitor with so many keys, lol. After it was all done, they made me a bunch of copies of the key, which was helpful and honestly unexpected because I thought I'd have to go to Lowes after to do that myself given the million and one copies we needed for various family members. Vibes: it was such a seamless experience with an incredibly friendly, helpful, technician who treated my house with respect (eg no outside shoes inside) and was patient with my questions/concerns. Cost: Pricing was all competitive with other companies I considered. Overall: An excellent experience; I'll only be using Danny Keys for my future lock change needs and recommending them to my friends and neighbors!

If you read my previous review, you'll see that I've had this company out twice since moving into…read moremy new home. This time was the third time. During the first visit, I was given the option of either re-keying my existing locks or replacing them entirely. I chose to have the locks re-keyed, thinking that would be sufficient. What I didn't realize was that re-keying can result in issues with how the key fits and operates in the lock. That service cost $900. Unfortunately, the new keys frequently got stuck halfway into the locks, making it difficult to unlock the doors. The company returned and spent about an hour adjusting the locks to improve the fit. I was not charged for that follow-up visit. While the keys worked better afterward, they still weren't operating as smoothly as they should. So, after another month of continuing to struggle with the keys, I decided to replace all of the doorknobs and deadbolts instead. That service cost an additional $1,299. The one positive throughout this experience was that the staff was always friendly and courteous.
