Why we drew the area this way
Three counties sounds arbitrary until you drive it. Glen Mills sits close to where all three meet, which means the Route 1 corridor, the Blue Route and I-95 all reach out from roughly the same starting point. Delaware County runs from the Main Line down to the river towns; Chester County opens west through the Brandywine Valley to Coatesville and Oxford; New Castle County picks up on the far side of the state line at Wilmington and Newark. Working all three from one base covers a genuinely connected area rather than three separate ones.
It also means the work itself changes as you move across it, which is worth knowing before you call. The older boroughs - Media, West Chester, Swarthmore, New Castle - are full of doors that were hung before the hardware on them existed, and a lot of what we do there is making a century-old door and a modern lock agree with each other. The postwar townships are more uniform: the same builder-grade deadbolt on thousands of front doors, most of it now well past the life it was specified for. Out toward Kennett Square, Oxford and Townsend the properties spread out and outbuildings, gates and barns become part of the conversation.
What actually decides whether we cover you
The county is the boundary, not the list. The towns below are the ones with pages of their own because they are where we are asked most often - but plenty of addresses sit between them, in a township with a mailing address that belongs to somewhere else entirely. That is normal here, and it is not a reason to assume we cannot come.
If you are not sure, the quickest thing is to call and read out the address. We will tell you plainly whether it is inside the area, and if it genuinely is not we will say so rather than send someone on a long drive to find out.
How the town pages are organized
Every town below has a page of its own. On it you will find the four kinds of work we do - automotive, residential, commercial and emergency - and under each one, every individual service written for that town specifically. So you can go from Glen Mills to automotive locksmith work in that town to car key replacement in that town, and the page you land on is about that job in that place rather than a general page with the name swapped in.
If you would rather start from the job than the place, the services index lists all 29 of them. Browse by service instead.
