I can’t say enough about the great experience I had with Sherlock lock! Arthur came to my house within 15 minutes. He was very cordial and worked hard in the misty, freezing weather to drill out my Yale lock pad so that I could get back into my house. What a nice guy! I highly recommend giving this business a call and to request Arthur if he’s available.

AK was incredibly helpful, kind, on time, and efficient. I really enjoyed his company as much as I was grateful for his professionalism. It was about $200 cheaper than the quote I got from the dealership AND he was there in less than 4 hours. Thank you so much AK!

Sherlock and AK are awesome! Great service, scheduled around my availability and location, fast and easy! Highly recommended. Now I won’t worry about losing my only car key because I have a spare at a much better value vs. the dealer.

AK came to my aid when I brought my 2014 Audi Q7 SuperCharged which I wasn’t familiar with and changed the battery in my key-fob which and of course it shut down the computer program…hey I’m new to the SUV lol! He came a few minutes ahead of time and had the job done in less than 10minutes and everything has been working perfectly ever since. His fair pricing had is so good I stored his number to my contacts. It’s my first time ever trying the business but I definitely will recommend it to EVERYONE needing the assistance. Great Company!

Wonderful quick service! Very professional! So nice! They come right to you ! Both my Jeep key fobs were not working! Needed to be re-programmed to my car. Dealership would have been $500 for 1 key fob! They did both of mine for $300! Would recommend!!!
