Is the bodyshop allowed to hold my vehicle if no work or supplement has been completed and they have not given an amount for storage fees?

Question Details: My vehicle was in an accident and was dropped off at a body shop. The employee that took the vehicle quit his job and left my vehicle outside with the keys in it. Unaware of this, a week later I called the shop for an update. The owner of the shop claimed to know nothing about the vehicle and actually said they did not have the vehicle at first. They had not called the insurance company for a supplement or even looked at the vehicle. I said that I was going to take the vehicle and they then claimed the starter had went without warning. I told them that I would be there the next day with a tow truck and specifically told them not to do any work to the vehicle. The next day the vehicle was moved inside and they refused to give me my vehicle because The owner of the shop is out of town for the next 4 days and there might be fees or parts ordered already. They called in a supplement with the insurance company after I had told them I was picking up the vehicle the previous day, which has since been canceled by the insurance company who is in full agreement with me on the entire situation. According to them they were only aware of my vehicle even being there for 1 day so are they legally allowed to hold my vehicle for potential fees and parts that they cant even give me an amount for?
