Losing the DESS key to a Sea-Doo, whether at the dock or somewhere in the water, brings the season to an abrupt stop until a replacement is sorted out.
Your Options
A spare key, if one exists, is the fastest fix. Without a spare, a dealer can usually program a new key, though this can take time and and typically is not cheap.
Confirming Everything Still Works
Once a new key is in hand, running the M-JET DIAGNOSTIC tool confirms the vehicle recognizes it correctly and that no related fault codes were left behind.
