Here's what you do. Lie. Lie through your teeth like a true parent. Say that it was a punishment for bad grades, or because she has a boyfriend, or because she doesn't have a boyfriend. The reason doesn't matter.
Seriously though, brass tacks. Are you talking about the metal clip that holds the RAM in or the plastic clip that holds the keyboard ribbon down?
Assuming it's the ribbon i'd go with Saga Lout's solution, just slap some tape on that bad boy, all the locking mechanism is there for is retension to hold it in place, and electrical tape would work just fine for that. Once that ribbon is in, it doesn't go anywhere.
As far as I know there is no "fix" for a broken ribbon ZIF connector.
