To keep your lock cores turning freely for years they require routine maintenance, just like the rest of your rack and vehicle.
We recommend that at least twice a year, more often if you live in a wet environment, or leave your racks on throughout the winter, you lube the locks. Our recommend lubricant is B'laster 8-GS Industrial Graphite Dry Lubricant this is widely available at most hardware, home centers, auto parts stores, and general retailers.
By keeping your locks lubed, you will keep them turning easily and prevent them from seizing up.
