How to test your vehicle's door to determine if they are made of aluminum or steel

Since DoorShox uses rare earth magnets to attach to your vehicle's doors it will only work with steel.

To check to see whether or not your doors will be compatible with DoorShox simply try putting a kitchen magnet (I.E. refrigerator magnet) near your door.

If you feel the magnet pulling DoorShox will work fine. If the magnet is not attracted to the door than it means your doors are Aluminum and DoorShox will not work.
