This document addresses concerns about the security risks associated with stolen vehicle owner’s and service manuals, specifically focusing on whether a vehicle can be stolen or compromised using information contained within the manuals.
Problem
Vehicle owner’s and service manuals for a 2016 Toyota Prado were stolen. The owner is concerned about the possibility of the vehicle being opened or started without the original key, using information from the stolen manuals. A related concern is the potential for unauthorized key duplication.
Solution
- Key Coding: While the manuals might provide information that allows someone to manually open the vehicle, starting the engine should not be possible without a properly coded remote/key. The immobilizer system requires a programmed transponder within the key to communicate with the engine control unit (ECU).
- Unauthorized Key Duplication: It is possible that information in the manual could be used to order a spare key.
- Recommended Actions:
- Notify the local Toyota dealer and request that they flag the vehicle in their system. This may help prevent unauthorized key duplication attempts.
- As a preventative measure when getting the vehicle serviced at a dealership, remove the manuals from the vehicle, leaving only the service manual if stamping is required.
