Periodically the hinges and latch assemblies on the doors,
Hood, and trunk, every 3000 miles or every 3 months should be lubricated lightly with light oil or lock lubricant. Also, it is wise to grease the door latch strikers to reduce on the amount of wear that happens while at the same time making it easy to operate the door. It is also recommended that the door and trunk locks are sprayed with a graphite based lubricating spray.
