New door lock installations are usually done by locksmiths. The locksmith should be properly bonded and insured to show their reliability and trustworthiness. Some stores that sell door locks might also have their own contractors for installations.
The cost of door lock installations depends on a number of factors, including the type of lock, the number of locks needed and the structure. Costs include setting up the area, installing the lock itself, making the keys and programming an electronic door lock. Some locksmiths or contractors also charge extra, according to the labor hours, setup time and debris removal. For commercial door locks, permits may be necessary.
