Master Lock Portable Key Lock Box 2-Pack 5400EC2 — 4-Digit Combination, Weather-Resistant

The Master Lock 5400EC2 Portable Key Lock Box 2-Pack lets you securely store and share up to five house keys using a resettable four-digit combination.

Skip hiding keys under mats or tracking handoffs: this pair of compact metal lock boxes provides a weather-resistant, easy-to-use solution for controlled access. Each box features a protective shutter over the combination dials, a vinyl-coated shackle to avoid scratching door hardware, and interior room for multiple standard keys. The boxes are portable for temporary use yet robust enough for recurring access needs like guest entries, contractor visits, or caregiver access.

How do I set and change the combination?

Each Master Lock 5400EC2 unit uses a four-digit, resettable code that you personalize without special tools. Follow the included instructions to choose a unique combination, then reset it anytime you need to revoke or update access.

• Four-digit code allows thousands of combinations for unique security
• Resettable mechanism designed for easy code changes as access needs evolve
• No key required to operate the lock box once the code is set

Will this fit my door knob or handle?

The vinyl-coated shackle is shaped to accommodate most common door knobs and handles—ball, biscuit, and tulip styles—so you can hang it quickly without tools. Its coating protects finishes, making it suitable for short-term attachment to customer or homeowner hardware.

• Shackle size designed to clear standard residential knobs and many lever handles
• Coating prevents metal-to-surface contact and reduces scratching
• Portable design allows use on different doors or temporary job sites

How durable is it outdoors and in daily use?

The 5400EC2 combines a solid metal body with a shuttered dial cover to shield the combination from rain, dust, and debris. While compact, it’s made to withstand typical outdoor exposures and repeated handling for rentals, real estate showings, and service access.

• Metal construction for reliable physical protection
• Protective shutter helps keep dials clear of moisture and grime
• Two-pack gives redundancy or separate boxes for multiple locations

How many keys will it hold and what are typical uses?

Each lock box can hold up to five standard (about 2-inch) house keys, offering flexible storage for households, short-term rentals, and professional access needs. Use it to streamline guest check-ins, enable contractor or caregiver entry, or keep a secure plan for emergency access.

• Holds several standard keys—handy for families or multi-user situations
• Ideal for vacation rentals, real estate showings, and maintenance visits
• Resettable code removes the need to reissue physical keys when access changes

Who is this for? The Master Lock 5400EC2 2-pack suits homeowners who prefer secure alternatives to hidden keys, rental hosts handling frequent guest turnover, real estate professionals managing showings, and caregivers or families arranging emergency access. If you need a portable, easy-to-manage way to share or control entry without producing duplicate keys, this compact, weather-conscious lock box pair provides a practical balance of convenience and reliable protection.
