Our services

Locksmith Services

MLine Locksmith is based in Devon and provides mobile locksmith service throughout the Main Line, for homes, businesses, and vehicles. This page lists everything we handle, grouped by where the problem is. Each service links to its own page with more detail.

Whatever the job, the process is the same: we come to you, inspect the lock, key, or door, explain your options, and give you the price before any work begins.

Not Sure Which Service You Need?

You don't have to know the name of the service before you call. "The key won't turn," "I'm locked out of the car," or "an employee left with a key" is enough for us to start. Give us a call, tell us what's going on and where you are, and we'll sort out the rest.

Urgent help

Emergency Locksmith Service

7 AM to 11 PM, seven days a week

Emergency locksmith help is available during our regular hours. We don't run overnight service. If you're locked out of a home, business, or vehicle, our lockout services page explains what to expect.

We'll give you a realistic arrival estimate when you call, based on your location, traffic, and technician availability.

Safes and Other Locksmith Work

We also handle safe opening, along with smaller jobs that don't have their own page, like mailbox locks, cabinet locks, and door closers. If you don't see your job listed here, call and ask.

How a Service Call Works

  1. You call and tell us what's happening and where you are.
  2. We confirm we can get to you.
  3. A mobile technician comes to your location.
  4. We inspect the lock, key, door, or vehicle in person.
  5. We explain your options and give you the price before any work begins.
  6. You decide whether to move forward.

We don't quote locksmith prices over the phone, because the condition of the lock, door, or vehicle changes what the job requires.
