I called MDM Locksmith and Mario was very professional, and friendly. He was able to change locks throughout my whole house in no time. Mario was even able to make a copy of a car key that I needed to get done in no time. Overall, good quality work by a locksmith that knows exactly what he is doing. I would recommend Mario as I have used him for two jobs so far. He even replaced the whole locks in my friends house for the basement, front door, back door, and even helped advise on what locks to buy. Mario knows it all when it comes to emergency lockouts, installing locks. He comes on time and always delivers quality and reliable service. The great thing is he will walk with you through the project and advise what is best for you based on your needs. The best locksmith in the city!
