The deductible amount is typically stated in the car owner's insurance policy, and it can vary depending on the type of policy and the car owner's insurance company. In some cases, the deductible may be waived, such as if the car owner has a comprehensive insurance policy and the stolen part is recovered.
If the car owner does not have comprehensive insurance, or if the deductible amount is higher than the cost of replacing or repairing the stolen part, the car owner may be responsible for paying the entire cost of the replacement or repair.
In some cases, the car owner may be able to recover the deductible from the person who stole the part, or from the person's insurance company. However, this can be a difficult and time-consuming process, and there is no guarantee that the car owner will be able to recover the deductible amount.
