Abstract: A payment schedule enforcement system and method cause various actions to be taken in response to nonpayment by the debtor. Such actions include remotely activating an alert message, disabling a vehicle or other product, or the like. Upon occurrence of a specified event, a message is sent to a remotely located device, such as one installed in a vehicle or other product. The remotely located device is configured so that it can disable the vehicle (for example by disabling the starter circuitry) upon receipt of the message from the operations center.
