"Rich arrived on-time and was very polite and professional."
He was able to re-key 5 locks (3 home/2 garage), as well as replace some older hardware. He worked steadily, explained the things that needed to be but didn't dumb it down too much, which I appreciated. He completed the work in a timely manner."

"Shawn and his team did a great job getting me back into my car. I would highly recommend AA Key and Lock in Overland Mo."  
"The remarkable part of Sean's work was that one of the four doors had a peculiar locking mechanism and the door vendor, and a door repair person, both told me that no locksmith would be able to rekey all of our doors onto the same key, given the peculiar nature of this one door. Sean did it easily, and now we're covered. He answered his phone immediately, came over at exactly the time we agreed upon, did the work very neatly and professionally, explained a few things more to me, and cleaned up well. I can't imagine a much better experience."

"I would definitely use this company again.  They were the cheapest out of 3 different companies within the area and did a great job!  Thank you AA Lock and Key!"
"We had our locks rekeyed after moving into our new home. Rich called 40 minutes prior to let us know when he'd be here and showed up 10 minutes early. My husband was home when Rich showed up and said Rich was able to get the locks rekeyed within 20 minutes. He was very courteous and professional. When I got home I realized that we were overcharged because we ended up not wanting to get one of our locks rekeyed. I called AA Lock and Key and they had Rich come back. He came back within 10 minutes, I wrote them a different check and he gave us 2 extra keys for the inconvenience. I would definitely use this company again. They were the cheapest out of 3 different companies within the area and did a great job! Thank you AA Lock and Key!"

"Professional. Courteous. Timely. Conscientious."
"Was on-time, even came right before he could charge me after hours prices but did not since he was in the area. WOW! Was calming to my nerves, and explained everything thoroughly PRIOR TO service, and explained the charges so clearly I had no questions.  He asked if I wanted something extra if it was inexpensive and worth it. I agreed, naturally.  I would not hesitate to call them again. I encourage those looking to call AA Lock and Key.   Professional.  Courteous.  Timely.  Conscientious."
