A new lock cover helps protect padlocks from snow, ice, salt and road grime that clog up the lock's inner workings. The Reda Lock Guard from Reda Innovations fits all “hockey puck” locks and is made of high-impact plastic. The cover is weatherproof, attaches with five earth magnets, and can be secured to the lock with a cable. Users can simply pull it off the lock when it's time to unlock their vehicle. www.reda-innovations.com
