MLine Locksmith is a veteran-owned Main Line locksmith based in Devon, PA. We provide mobile residential, commercial and automotive locksmith service throughout Chester County, Delaware County and nearby Main Line communities, seven days a week from 7 AM to 11 PM.
HOW WE WORK
We don’t quote locksmith jobs over the phone, because the condition of the lock, door or key changes what the job needs. We come to you, inspect the problem, explain your options and give you the price before any work starts. You decide whether to go ahead.
Call or message us
We're open seven days a week from 7 AM to 11 PM, and that includes emergency lockouts. Tell us what happened and we'll explain what comes next.
Based in Devon, close to most of the Main Line
We work out of Devon and head to nearby Main Line towns every day. Arrival times depend on traffic and technician availability, so we'll give you an estimate when you call.
Inspect first, then you decide
We look at the lock, door and key in person, walk you through the options and give you the price before we begin. Nothing starts until you say yes.
2023 / Serving the Main Line Since
WHO WE ARE
MLine Locksmith is a veteran-owned local business at 237 W Lancaster Ave Suite 219 in Devon. We’ve been serving homes, businesses and drivers around the Main Line since 2023. Lancaster Avenue runs through Devon, Wayne, Berwyn and Paoli, so those towns sit close to our office.
When you call, we don’t try to diagnose the job from a description. We come to the location, look at the lock, door or key, explain what we find and give you the price before starting. If a lock can be repaired or rekeyed, we’ll say so instead of pushing a replacement.
Our work is backed by a 1-year warranty on parts and labor.
Arrival times depend on traffic and technician availability. Corner tag: Open 7 days a week

Most people calling a locksmith want to know whether they’ll be oversold. Here is how we work:
Popular Locksmith Services
If the lock is in good shape, we can rekey it so the old keys stop working and you keep the hardware already on the door.
Lost or broken car keys replaced at your location, including transponder keys and key fobs.
New deadbolts installed and checked for a proper fit with your door and strike plate.
Not every smart lock fits every door. We check the door first, then install a compatible lock and test it.
Higher-security hardware with restricted keyways, designed to resist picking, bumping and other common attack methods.
A lock that turns hard or sticks doesn't always need replacing. We check the lock and the door alignment before recommending anything.
Locked out of your house? We'll come to you and open the door using the safest practical method.
Extra keys cut for your home, office or vehicle.
Locked out of your car? We'll come to you so you aren't waiting on a tow truck.
A key snapped off in the lock? We remove the broken piece and check the lock before you use it again.
