How much a Locksmith charges depends on a number of factors, including:
Where you live
The number of locks you need repairing
The type of lock involved if an emergency gain entry situation
Any parts required
Timing – an emergency locksmith is likely going to charge you more than a scheduled appointment.
Most Locksmiths should be able to give you a good idea of the price they will charge based on a description of the job required, but for more complicated tasks they may well ask to view the property before quoting and confirming the price.
The condition of any existing locks as well as any features or fixings connected to the lock to be worked on including door or window frames etc. can also impact the cost. A slightly warped door, frame or window fixing can extend the amount of time needed and this will affect the cost.
Obviously, you may wish to shop around for the cheapest available – though it’s unadvisable if you have issues with locking your home. In other cases the cost may well come down to simple geography; if there’s only one Locksmith in your area, you’ll have to go with them.
