Fill your pot with water (leave room for the corn!) Add the sugar. Drop in your corn. Bring everything to a boil, making sure the sugar is dissolved in the water. Boil for no longer than 8 minutes. Remove from the water and let it cool enough for handling and eating. Handle it and eat it.
Usually the locksmith will be able to rekey the locks in his service van. Most of the locks will take about 10 minutes to rekey and the locksmith can charge you anywhere from $10 to $30 for each lock rekeyed. Most locksmiths will include a few free keys. The locksmith will also charge you for the travel time to you.
Once the lock is opened up, we replace the 5 or 6 cylinder pins with new pins whose length corresponds to the notches in the new key. When reassembled, the lock will now operate only with the new key(s). Every Home Depot store has one or more associates who can re-key locks, and the cost is minimal.
