How we work

We are a mobile locksmith. We come to you.

What brings this up

Around Montgomery County, we get these calls when a key turns hard, a lock is loose, the cylinder is worn, or the key has broken off in the lock. Some locks have reached the point where replacement makes more sense than more turning and trying. We also see this after a move, after a lock has been forced, or when a key no longer matches what the door is doing. In homes, stores, and vehicle doors in places like Telford and Souderton, the problem starts at the lock.

What we look at first

Before we change anything, we look at the lock type and how it is built, since rim, mortise, and bored cylindrical hardware each handle replacement a little differently. We check whether the cylinder can be changed on its own or whether the full lock body needs to come out. We also look at the key, the way it enters, and the condition of the parts inside the housing. That tells us whether we are dealing with lock replacement or a cylinder change at the door.

The work, and where it stops

The work can mean taking out the old lock and fitting a new one in its place, or changing the cylinder and putting the same body back together. We come to you and do the work on site. We do not machine a cylinder, mill, ream, bush, file, or cut a keyway, and we do not turn the job into a repair that needs that kind of metal work. When the lock calls for more than replacement or a cylinder change, that is where the job stops.

Worth knowing

While we are working, people often ask whether the whole lock has to come out, whether only the cylinder can be changed, and whether the new cylinder can be matched to the existing key. The short answers are yes, yes, and only when the lock is built for that. We also get asked whether the hardware is rim, mortise, or bored cylindrical, and we identify that before we start. If the work falls outside replacement or a cylinder change, we leave it at the lock and key.

Questions about lock replacement in Montgomery County

My front door has one knob lock and a separate deadbolt. Does that change what gets replaced?

It changes the scope of the job. We need to know whether you want the knob lock changed, the deadbolt changed, or both, because they are separate pieces of hardware with separate cylinders or separate lock bodies. Tell us which key operates which lock now, and whether either lock sticks, because that can affect whether replacement or a different setup makes sense on that door.

I lost the key to my shop door, and the lock is built into the door edge. What does that mean?

That points to a mortise lock, and it matters because the cylinder and the lock body are not the same part. We can replace the cylinder if the body is staying in service, or replace the lock if the hardware calls for that. Tell us whether the key goes into the face of the door or into trim, and whether the inside handle still moves the latch.

My apartment door has a night latch on the inside and a key cylinder outside. Do both pieces get changed?

Not always. On that setup, the outside cylinder may be changed without replacing the inside body if the body itself is still the part you want to keep. If the inside mechanism is the problem, that is lock repair, which is a separate service we also do. Tell us whether your issue is the key side, the inside latch, or both.

The office back door has lever handles and a deadlatch, not a round knob. Will that limit replacement choices?

It can limit what fits the existing prep in the door. Lever hardware and a deadlatch use a different layout than a bored cylindrical knob set, so we look at the door’s current hardware style before any replacement is chosen. Tell us whether the key is in the lever or in a separate cylinder, and whether the latch is the part giving you trouble.
