Unrealistic pricing of Renault electronic key

I am driving a Renault Scenic, but due to a poor design I had to replace my electronic key now for the third time with a cost of R3 088. Because I do not have a choice, only Renault can provide me with this key and I believe Renault thus see this as an opportunity to ****** their customer because of this monopolistic control and dependency. This cost in my mind is totally unrealistic for a small electronic key, because of this absorbent price of over three thousand Rand, I can buy two decent kindles or a laptop. This was also not something they told me when I bought the Renault, and I want to make other people who may consider buying a Renault to be aware of this wrest.
