September 18 · C . AtkinsBest customer service, the young girl very attentive and very professional I’m glad to have them in south Chicago
August 06 · Manny AlvarezI called today and a woman answered the phone, I asked if she would be able to help me with letting me know if they could make a duplicate of my car key and possibly let me know how much it would be and her response shocked me! Instead of a simple “sure you got the right person I could help you with that, what’s the year, make and model of your car?” She ACTUALLY says “ I don’t know if we can or not (long pause) if you tell me the year make and model of your car that would help a lot wouldn’t it?!”I know this place is family owned and I was referred to them so I gave them a chance, but they need to learn how to address people properly ESPECIALLY if they are answering the phone! Yes she made me mad and yes I called her out of her name, because who are you?! Thanks but no thanks!
September 12 · Kristal MaciasHad trouble turning the key in my car, disassembled and took out my ignition cylinder which was seized and couldn’t turn over, they had it for about an hour and said it was ready, came back and ignition cylinder was working great, and they had honored my $50 quote, also gave me another key as well, went home put everything back together and now my car can turnover and start thanks to Harold’s lock and key service highly recommending them to anyone that needs a locksmith, it’s very convenient that they’re open of Saturday too.
August 10 · Ulises PadillaI purchased the use car that only came with one key fob. I went to them. They did not have a key fob, but they ordered it. And my final cost was about $170. Where is the dealership? Wanted to order the key five and reprogram it for me for $500
