Graphite Lock Lubricant

Graphite Lock Powder for Door & Cylinder Locks

Keep your lock working smoothly with our professional-grade graphite lock powder. Designed to reduce friction inside cylinder locks, this dry lubricant helps prevent sticking, stiffness and long-term wear.

Suitable for composite doors, uPVC doors and wooden door locks.

How to Lubricate a Composite Door Lock

Using graphite lock powder is quick and simple:

1. Apply a small amount of graphite powder directly onto your key using the precision nozzle.

2. Insert the key into the cylinder.

3. Turn the key back and forth several times to distribute the lubricant evenly.

This helps restore smooth, reliable locking performance.

What Should You Avoid Using on a Door Lock?

Avoid oil-based lubricants such as WD-40 on cylinder locks.

Oil-based products attract dirt and debris, which can clog internal pins and moving parts over time — often making the problem worse.

Dry graphite lubricant is the correct choice for long-term lock maintenance.

How Often Should You Lubricate Your Door Lock?

We recommend lubricating your composite or uPVC door lock every 6 months to maintain smooth operation and prevent premature wear.

One bottle provides multiple applications.
