KeyGuard SL-591 Car Window Lock Box - Black Portable Metal Key Safe with Push-Button Keypad

Designed to mount on a vehicle window, the SL-591 combines a robust metal shell with an easy-to-use push-button combination pad so you can leave keys or small items in a secure place without carrying them on your person. It includes a protective rubber cover to shield the keypad from weather and wear, and the combination is simple to set or change using the supplied tool. Internal dimensions are approximately 4" x 2-3/8" x 1-1/8" (4-3/8" diagonal), offering enough room for most car keys, fobs, ID cards and a little cash.

How does the SL-591 keep keys safe near my vehicle?

The box uses a solid metal construction and automatic locking when closed, creating a tough enclosure that resists casual tampering. The push-button keypad avoids exposed keyholes, and a flip-down protective cover obscures the buttons and reduces weather exposure.

• Full metal body with metal frame for structural strength
• Automatic lock when the door closes for one-step security
• Rubber cover protects keypad from rain, sun and dirt
• Push-button access eliminates vulnerable key cylinders

How do I use and change the combination?

Access is via a familiar phone-style punch-button keypad that accepts number or letter combinations. The set-up and combination change are straightforward using the included adjustment tool; no special skills are required.

• Enter your custom code on large, easy-to-press buttons
• Change combinations quickly with the provided tool
• Buttons are large enough for fast entry, even with gloves
• Cover conceals pad to prevent onlookers seeing your code

What fits inside and how much space is available?

The interior is sized for common everyday items: several house or car keys, modern key fobs, credit cards, IDs, and a little cash or a slim auxiliary item. The box’s compact footprint keeps it unobtrusive on a vehicle window while offering practical capacity.

• Internal space roughly 4" x 2-3/8" x 1-1/8" with 4-3/8" diagonal
• Holds multiple keys, one or two fobs, and flat valuables like cards
• Compact form factor mounts discreetly to a rolled-down window
• Works well for rideshare, car rentals, outdoor activities and home use

How durable is this lock box for outdoor or frequent use?

The SL-591 is built for repeated everyday handling: a heavy-duty metal shell with an ABS-type coating protects both the box and the vehicle surface it touches. The keypad and cover are made to withstand rain and sun exposure while remaining easy to operate.

• Solid metal core for impact resistance and longevity
• ABS-style outer coating prevents scratches to car paint
• Protective rubber keypad cover improves weather resistance
• Sturdy mounting and automatic locking reduce accidental openings

Who this is for: Drivers, property managers, rideshare and car-rental users, and outdoor enthusiasts who need a secure, portable place to leave keys or small essentials. If you want a simple, mechanical, keyless way to share access or keep spares nearby without electronic batteries or apps, the KeyGuard SL-591 provides a rugged, low-maintenance solution.
