About DRYFOB
DRYFOB® is a waterproof car key container suitable for scuba diving and other water sports. It fits all standard car key fobs, is neutrally buoyant with a key fob, and can sustain prolonged diving at depth. While primarily designed for shore diving, the waterproof case can work well for any activity where you want to protect your key from environmental hazards (water, humidity, mud, sand, etc.).
The patent pending DRYFOB car key container is machined out of a rugged aluminum alloy and anodized for additional strength and corrosion protection. Dual O-rings are used to provide a waterproof seal.
All of the DRYFOB sizes have been IPx8 Rated to 330ft (100m). Note that this is not a limitation, it is simply the parameters we specified for our certification testing.
The rugged construction and materials will stand up to repeated and prolonged use (as well as getting tossed around in your dive bag). The aluminum case also acts as a signal blocking Faraday cage.

DRYFOB now comes in 3 sizes
(1) The original DRYFOB car key container is designed to fit all standard car key FOBs. There are two attachment points that can accommodate a (not included) lanyard, bungee, ring, or clip. Most divers carry their DRYFOB in a BC pocket or clipped to a D-ring or other secure spot. It is neutrally buoyant (with FOB).
(2) The DRYFOB-L can house some of the larger key FOBs such as the Jeep, New Mazda, Buick and Volvo with a slightly larger interior cavity.
(2) The DRYFOB-XL can house all popular PLB (Personal Locator Beacon) sizes and is also good for those seeking more room for credit cards, driver’s licenses, small glasses, and more.

User instructions
Prior to use
The DRYFOB case uses two lubed O-rings which form a watertight seal in the enclosure when the top is screwed onto the base and fully closed against the raised lip.
- Be sure to inspect the O-rings prior to each use to ensure that there are no signs of cracking or wear, and that no debris is present that can prevent a proper seal
- Make sure that both O-ring gaskets are installed
- Lube the O-rings periodically with the included lube when they appear dry
- Replace the O-rings if there are signs of wear
After each use
- Rinse your DRYFOB car key holder in freshwater after each use and air-dry or wipe it with a lint-free cloth. Be careful with the lubed O-rings, making sure no lint or debris sticks to them that can interfere with the seal
DRYFOB! Finally, a waterproof solution for keeping your car key FOB dry and protected you can have confidence in. The DRYFOB rugged container is perfect for all water sports, even for scuba diving at depth!
