Nothing can be as frustrating as arriving at your destination than to find that you can’t open the door to your house, rental property, or place of business. We at Aaron’s Lock Service love the opportunity to help you. At the same time would like to give you some helpful hints on how to avoid problems with your locks.

I am going to address what I would call mechanical type locks. These locks have a cylinder that is pinned to the same code as your key. There are many different brands or makers of keys that fit specific locks that are designed for the key to fit into the keyway of a cylinder. A few examples are Kwikset, Schlage, Sargent and Yale to name a few.

These types of locks function because the cuts on the key, match the length of the pins in the cylinder chamber. The depths of cuts vary and if they all do not match; the key will not turn the cylinder to turn and unlock the lock.

One of the greatest enemies of mechanical locks along the coast is moisture, salt and sand. We have operated in Daphne, Mobile, Gulf Shores and Pensacola for over 20 years so we have lots of coastal experience.  These all cause the lock to corrode and at times to freeze. All locks eventually corrode or rust, even stainless steel. Lubrication and exercising the lock is vital to keep it functioning properly into the future.

We suggest several products to use in lubricating your locks. WD-40 is the first product I want to recommend. WD stands for water displacement, it is designed to remove moisture and lubricate at the same time. (We do not recommend the WD-40 with Silicone. Silicone can gum up the lock and trap sand or dirt inside).

PB Blaster is the other product we recommend. PB Blaster is especially effective with extreme corrosion situations. PB does have a stronger odor and can be messy so make sure you have a rag handy.


Graphite powder lubricant used to be recommended for locks but no longer. Graphite is a dry powder that when squirted into a cylinder, will enter the pinning chambers. When mixed with moisture, graphite will harden and pack causing the pins to not operate as they should.

Inactivity is also hard on locks. Make sure that you lubricate and exercise your locks on a regular bases or if this is a second home, when ever you can visit your property.

We also suggest that you have your keys duplicated from an original key and have a professional do it. Many duplicating machines at big box stores fall out of calibration and may not cut your keys accurately.

We hope this information will be helpful and we look forward to serving you in the future.
