A key that drags or a cylinder that feels gritty usually needs cleaning and the correct lubricant, not force.
Step-by-step guide
- Pick the right product Use a dry lubricant made for locks, such as a PTFE or graphite product. Oily sprays attract dirt and gum up the pins.
- Clean the key Wipe the key. A dirty or bent key causes many sticking problems on its own.
- Apply a small amount Give one short burst into the keyway. More is not better.
- Work it in Insert and remove the key several times, then turn it back and forth. Wipe the key each time it comes out dirty.
- Do the latch and bolt Put a little lubricant on the latch and bolt where they slide, then operate them a few times.
