Sorry, my friend, I'd love to help, but I don't really understand what the problem is.

Let me ask a few questions to clarify:
When you say that the key is slow to turn, do you mean that it is hard to turn the key in the ignition? Or do you mean that once you turn the key, the engine is slow to start?

Is it hard to turn the key in the ignition? If it is, then you've got a common problem. The ignition cylinder will need replaced. If it's under warranty, get it replaced as soon as possible. If you don't, it will eventually stop turning all together, and leave you stranded. If it isn't under warranty, you still need to get it replaced, but you'll need to save up. It's not cheap.

If the car is slow to start once the ignition is turned (with the key) that could be a host of other problems, and it's hard to say what. Again, get it fixed as soon as possible, as it will likely only get worse, and leave you stranded somewhere very inconvenient.
