Frequently Asked Questions

It’s a dry, powder-based lubricant designed specifically for high-security cylinder locks (and other key-operated locks). It reduces friction inside the lock, helping keys turn smoothly and preventing sticking, jamming or wear.

Unlike oils or grease, graphite powder doesn’t attract dust, dirt, or grime — so it avoids sticky buildup that can clog lock internals. It also remains effective in varying weather or temperature conditions and won’t freeze or evaporate.

Simply apply a small “puff” of powder into the keyhole (or onto the key), then insert and turn the key several times to work the graphite through the lock mechanism.

For normal indoor use, every 6–12 months is usually sufficient. If your doors/locks are exposed to dust, moisture, or heavy use, you may wish to apply more frequently.

Yes — by reducing internal friction and preventing wear, rust, or corrosion, graphite powder helps maintain lock performance over time and prolongs the lifespan of high-security cylinder locks.
