A price needs
a job description.
A house lockout, a rekey for several doors and a missing programmed car key are different jobs. The location, hardware, vehicle details and amount of work all help define the estimate. Tell us what happened and what you want to achieve.
There is no single published flat price on this website. Ask what the visit, labor and parts include, and whether any cutting, programming or additional fitting is separate. If the final scope requires an inspection, clarify which amount is provisional and what could change it.
Keep the decision in your hands.
Before approving work, make sure you understand the proposed solution. Opening a door and changing which keys operate it may be separate tasks. Repairing a lock and replacing it also have different implications for parts and key handover.
If another issue is discovered, ask for the additional work and revised price to be explained before proceeding. For a rented home or business, involve the person authorized to approve the scope and cost.
