Master locksmith Shawn Fago suggests using a pencil type graphite lubricant designed specifically for lock-cylinders.
Liquid lubricants may be more effective than graphite particularly in humid climates. Silicone lubricants are resistant to water and do not attract dust and dirt as much as other liquid fluids. They are suitable for both low and high temperatures. However, some silicone lubricants may create accumulation over time and could be displaced by other lubricants that you've used.
