Best Locks for Central Coast Beach Houses

Lock corrosion on the Central Coast is a big problem for many home owners, and while many lock brands claim they are ideal for outside conditions, not many can stand up to coastal breezes that dump highly corrosive salt over your house. 

Which is the best locks for coastal areas?  The best locks to cope with coastal salt air are locks made of 316 grade stainless steel. While most locks are made from various metals, the most important components of the lock  you are looking for to be made from stainless are the screws, face plate, latch and lever furniture.  The internals or mechanics of a lock are usually made is mild steel, cast iron, brass and spring steel and the best way to protect these vital components is to lubricate with lubricant that repels water such as Inox, WD40 or a silicon spray. 

Satin Finish Lever Handle

The photo above clearly shows corrosion over a approximately 10 year period. Interestingly this lever handle is actually a quality handle but it’s just not suitable to withstand coastal conditions.  As a general rule, I recommend using only stainless steel handles and make sure to lubricate the internals of the lock. For the key barrel, many locksmiths will strictly say to not use WD40 in the lock barrel. This is because oil based lubricants attract dust and clog up the lock. While I agree in principle, not using a water repelling lubricant in the barrel will result in the key not working in the lock. 

Recently I was a brand new water front beach house with satin finish lever handles and they were already starting to show corrosion. It just shows how quickly salt can affect locks. 

So the best advice I can give is to go to the extra expense and use stainless steel handles where possible and lubricate the lock with a water repellent lubricant.
