Every Lock, One Key™

With PACLOCK, customers are using the best locks to secure their applications — whether it be a Rigid job box, a gate, the side of their vans, or their trailer doors — while having the ability to use one key to open all their locks. As a result, customers trim down their key ring and save time.

High-Performance Padlocks

Innovative Design
PACLOCK’s locks are engineered specifically for each unique application. Depending on the lock, special security features may include a “hidden-shackle” design preventing common shackle-cutting attacks, stainless-steel pins preventing common grinding attacks, and a PAC-BAND silicone cover keeping dirt and grime out of the cylinder helping the lock maintain smooth operation.

6-Pin Cylinder Technology
PACLOCK’s solid body padlocks six-pin cylinders rather than the industry standard of four, allowing for over thousands of key changes. Your key number is virtually unique to you! PACLOCK cylinders are best in class for pick, bump, or any other type of surreptitious entry attacks. This is standard across all products, whereas other manufacturers make you pay to upgrade for similar technology.

How to Buy PACLOCK

  1. Start with your application. Our locks are built for every unique application.

    PACLOCK has two primary lock series: UCS Series and Standard Rekeyable Series locks. Ultimately, PACLOCK’s UCS Series locks provide higher security and withstand better in weather than Standard Rekeyable Series locks.

  2. For PACLOCK’s UCS Series locks, select any key number between #43001-63224. For PACLOCK’s Standard Rekeyable Series locks (non-LOTO and non-government padlocks), you can either choose between twelve standard key numbers or select your own key number between #93001-95802.

  3. Order all your UCS locks to the same 5-digit key number so all your locks can be opened with one key! Similarly, select the same key number for Standard Rekeyable Series locks each time you’d like to key all your locks alike.
