Thanks folks for all your suggestions. I collated them, printed them out and gave them to my friend. She had some good chuckles by some of the responses and was impressed by the wide variety of suggestions.
She bit the bullet and took her car to a locksmith. They had a tough time trying to pick teh lock, and in the end had to resort to drilling it out. Fortunately they had a another lock that would fit, so it got re-keyed to fit the car keys and 3 new sets of car keys were made. She drove off only $22 lighter. She also purchased a can of Teflon based lubricant for the winter months. This was a suggestion from the locksmith as she has always had difficulty with this car's locks in the winter months.
She's a happy camper and passes along thanks to my 'funny and creative friends."
