My Buying Guides on Magnetic Key Box For Car
When I first looked for a magnetic key box for my car, I realized there are several important factors to consider to make the best choice. Here’s what I learned and what helped me pick the right one.
1. Size and Capacity
I checked the size of the key box carefully because I needed it to fit not only my car key fob but also a few other small essentials like a spare key or a garage remote. Most boxes come with enough space for one or two keys, but if you want to store more, look for a larger model.
2. Strength of the Magnet
The magnet’s strength is crucial. I wanted a box that sticks firmly to my car’s metal surface so it won’t fall off while driving or during bad weather. I looked for boxes with strong neodymium magnets because they offer reliable adhesion even on uneven or dirty surfaces.
3. Weather Resistance
Since the key box is mounted outside the car, it needs to withstand rain, snow, and extreme temperatures. I made sure to pick a waterproof and rustproof box, usually made from durable materials like heavy-duty plastic or metal with protective coatings.
4. Security Features
Security was a big concern for me. Some magnetic key boxes come with combination locks or keyed locks to prevent unauthorized access. Depending on your comfort level, choose one that offers the right balance between convenience and security.
5. Ease of Installation and Removal
I appreciated a magnetic key box that was easy to install and remove without tools. This made it convenient for me to take the box off when needed or move it to different locations on my vehicle.
6. Design and Discreetness
I wanted the box to blend in with my car’s exterior so it wouldn’t attract unwanted attention. Many boxes come in black or dark colors and have low-profile designs, which I found helpful for keeping the key hidden.
7. Price and Warranty
Finally, I compared prices but also checked if the product came with a warranty or satisfaction guarantee. Spending a little more for a reliable brand gave me peace of mind that my key box would last and perform well.
My Final Tips
- Always test the magnet’s grip on your car’s surface before purchase if possible.
- Keep the key box clean and check it regularly for any damage or wear.
- Consider where you’ll place the box on your vehicle for maximum security and convenience.
By keeping these points in mind, I found a magnetic key box that suits my needs perfectly and gives me confidence that my spare key is safe and accessible.
