Rochele JonesEmergency lockout, broken key, lock repair
My key was stuck in the front door on the first day with clients at my new business. Someone came out within 20 minutes, fixed the problem, and kept me from canceling a full day of appointments.
Cassie BellmanKey fob replacement and programming
Highly recommend. Excellent service and response. AK came out to me, replaced the key and fob for my Range Rover Evoque, and finished much quicker than expected.
Phil SegoCar key copying and reprogramming
This was the second time I used Sherlock Lock. AK ordered the replacement and came exactly when he said he would. Efficient, knowledgeable, trustworthy, and fast.
