Buyer's Guide

What to Look for in a Garage Safe

Size & Capacity

Measure your garage space and consider what you'll store. Large safes like the MLJ 17.5 cu.ft model handle bulk items, while compact boxes work for documents and cash.

Lock Type

Digital keypads offer quick access and code changes. Smart WiFi locks provide remote monitoring. Traditional key locks remain reliable for basic security needs.

Fire & Water Resistance

Garage environments face temperature extremes and potential flooding. Look for safes with certified fire ratings and water-resistant seals to protect contents.

Smart Features

WiFi connectivity enables remote monitoring, access logs, and tamper alerts. These features add convenience but require power and internet connection.

Installation & Mounting

Heavy safes need solid flooring. Wall-mounted lockboxes require sturdy surfaces. Consider delivery access and whether you can bolt the unit down securely.

Price & Value

Balance security level with budget. A basic keypad safe costs under $100, while smart large-capacity models exceed $500. Factor in long-term durability.

Frequently Asked Questions

Safety and Security โ€” FAQ

What size safe do I need for my garage?
Choose based on what you're storing. For documents and jewelry, 0.5-1 cu.ft suffices. For tools and equipment, consider 10+ cu.ft models like the MLJ 17.5 cu.ft safe.
Should I bolt my garage safe to the floor?
Yes, always bolt safes exceeding 100 lbs to concrete floors using anchor bolts. This prevents theft and tipping. Lighter lockboxes can be wall-mounted for convenience.
Do I need a dehumidifier in my garage safe?
Garages are prone to moisture. Silica gel dehumidifiers like the wisedry 500g packets prevent rust on firearms and protect electronics. Recharge them monthly in a microwave.
Are smart safes worth the extra cost?
WiFi-enabled safes provide remote monitoring and access logs, ideal for frequent travelers. For basic home use, a quality digital keypad offers sufficient security at lower cost.
What's the difference between a safe and a lockbox?
Safes offer heavy-duty construction and fire protection for valuables. Lockboxes like the Puroma provide convenient key storage but lack the security rating for high-value items.
Can I install a garage safe myself?
Safes under 50 lbs are DIY-friendly. Heavy models like the MLJ 17.5 cu.ft require professional delivery and installation due to weight and anchoring requirements.
Final Verdict

๐Ÿ† Bottom Line

The MLJ Extra Large Safe Wifi Smart Safe dominates with unmatched 17.5 cu.ft capacity and smart monitoring, making it the ultimate garage security solution for serious homeowners.

Budget-conscious buyers should consider the KYODOLED Safe Box for basic valuables, while those needing tool storage will find the Greenvelly Cabinet offers pro-grade organization with lockable security.
