Over time, locks can become rusty, which hinders their secure functionality. Rust formation occurs when metal locks are exposed to moisture, making them susceptible to corrosion. This results in various types of issues, including jammed locks. A jammed door lock can range from an annoyance in operating the lock or the key breaking in the lock to a big trouble like getting locked out of your home.

However, with some simple maintenance and prompt repairs, you can keep your locks in tip-top shape and save yourself the headache from rusted locks. In this article, we’ll explore ways prevent rust and offer guidance on how to deal with rusty door locks.

Maintenance Tips for Rust Prevention

Moisture is the main culprit behind rust and corrosion, so it’s essential to minimize its impact. Outdoor locks are especially vulnerable with prolonged exposure to moisture, so they need even more attention to ensure they don’t get corroded. With some simple lock maintenance, you can make your locks last long and reliably and avoid getting rusted amid humidity.

Keep an Eye on Your Locks

It’s important to keep an eye on the condition of your locks now and then. The faster you catch issues like the formation of grime, the easier it is to deal with, and the less likely it is to catch you by surprise. Take a moment every now and then to inspect your locks and ensure they are in good shape.

Clean Your Locks

Excessive accumulation of dirt, grime, and moisture can contribute to rust formation. To prevent this, give your locks a good cleaning. Use a can of compressed air to blow away the grime and moisture that may have accumulated. This simple step can go a long way in maintaining the functionality and appearance of your locks. Remember to handle the cleaning process gently to avoid damaging any delicate components.

Lubricate Your Locks

Lubricating your locks isn’t only essential for their smooth operation but also plays a vital role in preventing rust formation and jammed door locks. When you lubricate your locks, you create a protective barrier that shields them from moisture and loosens any debris, which decreases the likelihood of rust and friction.

Before you reach out for your handy WD-40 spray, keep in mind that oil-based lubricants aren’t recommended for lock mechanisms! Instead, use a silicone or graphite lubricant. Before you apply a lubricant within the keyhole, remember to clean it first with the aforementioned tip!

When you apply the lubricant, insert the key and turn it around inside of the lock so that the lubricant is adequately spread within the lock mechanisms.

Apply a Rust-Proof Primer

For added protection against rust, consider applying a rust-proof primer to your locks. This protective layer acts as a barrier against moisture, significantly reducing the chances of rust formation. You can find rust-proof primers at your local hardware store. Applying a coat of primer to your locks is an extra step of precaution that can help prolong their lifespan and keep them looking their best.

What to Do With Rusted Door Locks

If you notice that your lock has developed rust, it could be an indication that the metal of the lock has already weakened significantly. Rust is a corrosive process that can deteriorate the structural integrity of the metal over time. In such cases, it’s generally advisable to replace the rusty door lock rather than trying to salvage it.

In some cases, however, repairing a mildly rusted lock may be possible through WD-40. Spray a generous amount of WD-40 into the keyhole. Let the lock sit in the lubricant for about one hour. Afterwards, you can turn the key around the keyhole in order to remove any loosened rust.
