First, evaluate the severity of the situation. If the weather presents a life-threatening risk from prolonged exposure, find shelter nearby if possible and call 911.
If at-risk children or adults are left in the car, call 911.
If there is not an immediate risk, evaluate whether obtaining a spare set of keys is reasonable. If it is not, call the Pella Police Department at 641.628.4921. Officers will be able to attempt a vehicle unlock. Callers should expect to accept all risk (damages, etc.) involved with the vehicle unlock.
