I called to inquire about a replacement key and the woman that answered the phone was very dull, dry and unfriendly when answering. After she answered the question of what I called about, I told her that was all I needed and thank you. She just hung up. No 'thanks for calling', 'have a good day' or anything. So I called back. She answered again the same way as before. I told her that it was very unprofessional how she hung up and she hung up again! I will never call them again, even if their services were FREE!

The service was fast and the service man was courteous and more than I expected. Their price was the most competitive. Glad I called them last as they gave me the best price to have a key made for my Lincoln without even taking the lock out!
