Built for solid, versatile security on trailers and gear, Master Lock padlocks handle doors, couplers, spare tires, bike racks, hitches, and even trigger locks. Choose keyed alike sets when you want one key for multiple locks, and match the shackle to the opening for proper fit. If keys go missing, some do not offer replacement keys and may require a locksmith, while combination trigger locks let you reset the code.
Yes, some Master Lock padlocks are available keyed alike, including multi-packs. Look for a keyed alike option when you choose the locks. We've seen sets like three discus locks with 3/8" shanks keyed alike, and even larger groups using the same key. Double-check that the keyed the same box is selected before adding to cart.
Match the shackle diameter and clearance to the hole and hardware—if your application has a 3/8" hole, use a lock with a 3/8" shackle. Some locks may be too large for a trailer tongue or may not fit certain hitches or bike racks, so measure before you rely on it. For long-term outdoor exposure to snow and rain, rust can seize a lock; inspect and maintain as needed.
Open and remove the lock, then push the lever down. With dials on the current combination, press the reset button on the left side in toward the center and keep pressure on it. Set your new combination on the dials, then release the reset button. The new combination is now set.
For many Master Lock padlocks, replacement keys are not provided; a local locksmith may be able to make new keys using numbers on the lock. For Master Lock trigger locks, replacement keys are not available and a locksmith will need to drill out the cores if the keys are lost. After removal, replace with a new lock set.
