Checking the front door lock
Checking the front door lock costs ten minutes now, or a fortnight later.
A lock that sticks is a lock that is about to fail, and it fails on the coldest evening of the year.

Worth doing
- Oil the cylinder once a year, and never with grease.
- Replace the cylinder rather than the whole lock when a key starts to wear.
- Change the cylinder when a key is not given back.
