On the drivers side I am unable to unlock the car. If I put the key in the barrel it won't turn. even if I press the barrel in and turn. Its the earlier version before they had the button under the mirror.
It could be key or barrel wear, or possibly a gooked up lock. I would try some oil in there and keep trying to turn the key gently. I don't know about TVR locks but not engaging the key fully sometimes helps with worn locks and keys.
