Great for car door locks, ignition locks, home entry locks, pad locks, etc.

Works well for intended use, helping lubricate some older locks in the house. Key just glides in and turns easily now.Have found a bunch of other items to use it on - bike lock, squeaky hinges. Yeah it’s messier, but spray lubricants just stink.
