saved my butt

Kudos to Jeff at CITY LOCK, Boulder, for saving my butt again. I tend to lose keys, or break them..and Jeff is THE GURU on getting me back down the road on my vintage 1977 Collectible Motorcycle. Other Locksmiths have not been able to accomplish what he has done, and he has saved me TWICE( you think Id learn..) Un-enthusiastic? Ive sent many people to Him BECAUSE of his Knowledge and enthusiasm( Ive told clients..He may talk your ear off..only because he knows this stuff so well..go ahead..quiz him..) Well, Jeff has taught me that all is not lost when It comes to my carelessness, and should be awarded a medal of honor. At one point, he made a key out of 2 ''halves '' of a brittle key that had broken. Wow. I would Recommend City Lock for not just Auto, but for all of your home security( they even carry Safes) . I can always count on an expert Like Jeff to help out. I Hope I never need his services again (if I get my act together)...I have since '' backed up'' my keys..and been more careful. Thank You Jeff! I will try to model my own customer service after yours, and strive to be an expert like you. Thanks for always helping out, quickly, and at a very fair price.

Dave, Your words are beyond kind. I really enjoy what I do. Thank you for sharing it with the webisphere! Jeff

while I waited

I brought my ebay-sourced automotive chip keys to Jeff and he programmed them while I waited. Shouldn't have wasted my time buying keys online. He's got them all there, and likely better product than what you get from web resellers. Very convenient on 30th near Valmont. highly recommended.

Gary, Thank you so much for the review. You just can not buy advertising that is as powerful as a referral. Your extra time to make a review is truly appreciated. Jeff

For months I delayed having my car lock fixed worried about the expense. Once I decided to go ahead I was delighted to discover the very affordable deal and joyful service offered at City Lock! I Warmly Recommend!

Hannah, Thank you so much for taking the time to post a review. It is amazing how we will kind of get used to problems that creep up slowly. When we finally get them taken care of, it is often one of those "Why didn't I do this ages ago" moments. I really do appreciate your sharing with the larger community. Jeff
