FAQ's
PACLOCK’s Universal Cylinder System™ (UCS™) gives you total flexibility — choose Keyed Alike (all your locks open with the same key) or Keyed Different (each lock has its own unique key). With our U-PICK!™ option, you can even choose your own key number when ordering keyed alike, or let PACLOCK assign one for you — either way, you get total control and simplicity.
UCS™ works across a wide range of lock types — from padlocks to trailer locks to job box locks — all using the same key system. It’s the best choice for new PACLOCK customers who want simplicity, scalability, and control.
Our Standard Rekeyable (SR) line is ideal for customers who already have padlocks from other brands like Master Lock or American Lock. These locks are designed to be cross-keyable, allowing PACLOCK padlocks to work with your existing keys and key systems.
That means you can upgrade to PACLOCK — and start benefiting from quality manufacturing, faster lead times, and better durability — without replacing all your current padlocks. It’s the easiest way to switch without the high cost or hassle.
Already using SR and thinking about switching to UCS™? Reach out — we’ll help you make the transition easy.
