Here in the Pacific Northwest region of Washington State. It is important to keep you auto, RV, motorcycle, home and business locks lubed, preventing a lock out situation. Lubing your locks several times a year helps displace moisture and helps keep your locks from sticking during a freeze. Yes, there are many lock lubes out there on the market but Abracadabra's preferred lube of choice would be a Teflon based lube. It goes in as a spray and leaves a Teflon film on the wafers or pins. Next time you have Abracadabra Locksmithing out, ask if they might have some of that special lock lube on their service vehicle.
