Over time wear and tear can lead to malfunctions but with proper care and maintenance you can extend the lifespan of your car door locks. Here are the best ways to make your car door lock last longer before malfunctioning.

Exterior Cleaning: Dirt and grime can accumulate around the lock cylinder. Use a mild detergent and water to clean the exterior of the lock regularly.

Interior Cleaning: Insert and remove the Key a few times to dislodge any dirt inside the lock. You can also use a can of compressed air to blow out any debris from the keyhole.

Use Graphite Lubricant: Graphite powder is ideal for locks as it lubricates without attracting dirt. Apply a small amount into the keyhole and work the Key in and out to distribute it.

  • Protect Against Moisture

Use Weatherproof Covers: Protect your locks from rain, snow, and moisture with weatherproof covers.

Regular Maintenance: Inspect the locks for any signs of rust or corrosion and address these issues promptly with appropriate rust removal products.
