The cost of a home-related job can vary depending on the task you ask the locksmith to do and if it's an urgent situation. The amount a residential locksmith charges to open a door can also depend on the time of day you need it. The hourly rate of hiring a locksmith is also determined by the location of your home and whether you call during peak hours. For instance, getting a locksmith to change door locks during peak times (morning and night) will be more expensive than a service call during the slowest hours of the day. From wanting more security to an emergency, these are the costs you can expect when contacting a nearby locksmith.
