Common Questions

Frequently Asked Questions

Do you stock replacement parts for older Schlage locks?

Yes. We maintain a deep inventory of Schlage AD series parts including reader modules, escutcheons, baseplates, spring cages, levers, latches, and communication modules — for both current and legacy products. If we don't have it, we can typically source it within 1–2 days.

How fast can you ship?

Most in-stock orders placed before 3pm ship the same day via UPS. Standard UPS ground delivers to most of the continental U.S. within 1–2 business days from our Holland MI, St. Louis MO, or Tampa FL locations.

Can I order just one or two pieces, or do you have minimum order requirements?

No minimum order requirements. We serve end users and contractors of all sizes — whether you need one replacement credential or a full case of 500.

What credential technologies do you stock?

We stock the full range of HID Global credentials including legacy 125kHz proximity cards and fobs, 13.56MHz smart card credentials (iCLASS, iCLASS SE, iCLASS Seos), and FIPS201-compliant options. If you need help identifying the right credential for your existing readers, we can assist.

Can you help me identify a part I need?

Absolutely. Send us a photo or the model number of the product and we'll identify the correct replacement part. Our team has deep product knowledge across all brands we carry.

Do you carry products for electrified door applications?

Yes — we stock electric strikes, magnetic locks, power supplies, electric hinges, request-to-exit bars, lockdown buttons, door position switches, and armored door cords from brands including Von Duprin, Locknetics, and LCN.
