Do not use Nova locksmith. I needed a repair and a technician by the name of Alex Brachian came over and claimed I needed to spend $800 on a new front door lock. When I called to follow up with the main office to find out what the brand of this insanely expensive item, the guy on the phone would not disclose what he had ordered for me! These folks are crooks. Stay away unless you get locked out in the middle of the night and can find no one else.
