Absolutely Amazing!!! Fast & Efficient! I locked my keys in my car and was in a rush to meet a deadline. I called Master Lock & Security after calling another local locksmith who said they couldn't get there in 20 minutes. Master Lock & Security said they could be there in 10. They arrived in less then 5 minutes after I hung up the phone and had the car unlocked and payment processed in less than 5 minutes. The whole process took less than 10 minutes and I was able to meet my deadline. I very highly recommend Master Lock & Security. Especially if you're under a time crunch. Great customer service too!
