High-security locks in Bethlehem, PA

Mul-T-Lock, Schlage Primus and ASSA Abloy cylinders: keys that cannot be copied at a kiosk, and locks built to resist picking, bumping and drilling.

What makes a lock high-security

Three things, and a lock needs all of them. First, a restricted keyway: the key blank is patented and only sold to authorized locksmiths, so copies can only be made by us, with your authorization card. Second, a pin stack or sidebar design that defeats bumping and ordinary picking. Third, hardened inserts that stop a drill. A deadbolt from the hardware store has none of these; a Mul-T-Lock, Schlage Primus or ASSA Abloy cylinder has all three.

The practical benefit for a home is key control. If you have ever handed a key to a contractor, a cleaner or a tenant, you have no idea how many copies exist. With a restricted key, you do, because every one of them was cut by us against your card.

The brands we carry

Mul-T-Lock

Telescoping pin design, interactive key element, and a wide range of cylinders for residential and commercial doors.

Schlage Primus

A sidebar that works alongside the standard pins. Fits existing Schlage hardware, so you keep your levers and deadbolts.

ASSA Abloy

Restricted keyways and sidebar cylinders used in institutional settings. Strong choice for businesses with many keyholders.

Retrofit cylinders

Most of these drop into the deadbolt or lever you already own, so the upgrade is the cylinder, not the whole lock.

Who asks for this

Homeowners who have had a break-in and never want to wonder about a key again. Landlords with a dozen doors who want a master key that cannot be duplicated. Shops with staff turnover. Anyone who keeps something valuable behind one door: a home office, a gun safe room, a garage full of tools.

We will tell you honestly when it is overkill. For a lot of homes, a Grade 1 deadbolt and a reinforced strike plate do more than a restricted cylinder would. For the rest, this is the right tool.

High-security questions

Can I get copies made somewhere else?

No, and that is the point. Copies come from us, cut against your authorization card, and we keep a record.

Do I need to replace my whole lock?

Usually not. Schlage Primus in particular fits existing Schlage hardware, and Mul-T-Lock and ASSA Abloy make retrofit cylinders for most common locks.

Is a high-security lock pick-proof?

Nothing is. These are built to resist the methods that open ordinary locks in seconds, which is what matters in practice.
