Setup, Compatibility & Care
To begin using your Master Lock, simply insert one of the provided keys into the cylinder, turn it to release the shackle, and press the shackle back into the body to lock. When not in use, keep the keys in a secure location. Because the lock uses a mechanical cylinder, it is recommended to apply a dry lubricant to the keyhole once a year if the lock begins to feel "sticky" during operation. Avoid using heavy oils or grease, as these can attract dirt and clog the 4-pin mechanism over time. The lock is maintenance-free otherwise; simply wipe the vinyl surface with a damp cloth if it accumulates dust or grime.
