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.
Some cars would need to just be rekeyed, while some car locks need to be replaced entirely because rekeying them would be so much harder. You could hire a professional locksmith service, like those in Las Vegas, to change your door locks for $30 to $50 per lock. Rekeying them is cheaper at $6 to $20 each lock. Changing your car locks would sometimes mean replacing your ignition lock too. You can inquire at your local auto parts store and buy an ignition switch with key for around $25. You can have your new ignition switch installed at a repair shop.
