Yup, only two keys, and one is wasted upgrading top speed from level 2 to level3. Best use for the other two is upgrading top speed from level 3 to 4 and from level 4 to 5. If you have level C upgrades lying around you can also upgrade nitro

Thankfully this is not a super expensive car to upgrade.
