What makes a locksmith mobile
A mobile locksmith works from a vehicle fitted with key-cutting machines, programming tools, common lock parts and the tools for opening doors. Instead of taking a lock or a car to a shop, the shop comes to you.
When it helps most
Lockouts, obviously: nobody can take their front door to a shop. Car keys too, since a lost key otherwise means a tow to the dealer. It also helps with jobs that involve many doors, such as rekeying a whole house or setting up a master key system in an office, where removing every cylinder and driving it somewhere would waste a day.
What a mobile visit can't always do
Some push-to-start fobs and certain European cars need dealer equipment. Some high-security cylinders need factory-cut keys ordered with a registration card. A good dispatcher asks about the vehicle or lock up front and tells you if a mobile visit will not solve it.
How to hire one well
Ask for an estimate before anyone is sent, and ask what the service call fee is. Ask the locksmith to confirm the total on site before starting. Expect to be asked for ID; it is a good sign, not an inconvenience. In California, locksmith companies are licensed by the Bureau of Security and Investigative Services (BSIS), and you can ask for a licence number and look it up on the Department of Consumer Affairs website.
Help the locksmith help you
Give a precise location: the cross street on the peninsula, the gate and village name in Newport Coast, the parking level and space at Fashion Island. Say what kind of lock or car it is. A photo sent ahead can save a second trip.
