Key Alike Custom Lock Pinning (KA)

Our in-house key alike cylinder pinning service (SKU: KA) allows homeowners, facility managers, builders, and commercial contractors to have multiple compatible door locks, deadbolts, window locks, and padlocks custom-pinned so they all operate on one single key. Performed at our stocked Victorian warehouse prior to dispatch, this key alike trade workshop service eliminates bulky keyrings while saving up to 80% compared to an on-site callout ($14.95 AUD standard rate for 1 to 4 locks, dropping automatically in your cart down to $9.95 AUD per lock for 20 or more locks).

Key Alike Locksmith Service: How Custom In-House Pinning Works

When you buy standard locking hardware off the shelf, almost every box is packed as Keyed to Differ (KD), meaning every deadlatch, deadbolt, patio bolt, and shed padlock requires a separate key. By adding our key alike locksmith service to your cart alongside your chosen hardware, our qualified Victorian locksmiths unbox each compatible lock at our pinning bench, strip the brass cylinder plug, and re-pin the internal brass tumblers to match a single new factory key code.

Step 1 — Count Your Compatible Cylinders: Count the total number of keyed barrels in your cart that you want matched together. A single-cylinder entrance leverset, deadlatch, or padlock counts as 1 unit of SKU: KA, whereas a double-cylinder deadlock or double-sided deadbolt (with keyholes on both sides of the door) counts as 2 units of SKU: KA if you require both sides pinned as key alike cylinders.

Step 2 — Select Quantity & Optional Grouping Note: Enter your total cylinder count into the quantity box above (or click a bulk tier button) and use the optional Keying Grouping Instructions box if you want your order split into separate sets—such as matching your front and back doors on Group A while matching six gate padlocks on Group B.

Step 3 — Bench Testing & 2 Matching Keys Per Group: Every re-pinned barrel is hand-tested for smooth plug rotation before re-boxing for 24 to 48 hour dispatch. Each keyed-alike group is supplied with 2 matching factory-cut brass keys as standard.
