You would need to have the ECU/control unit/receiver that receives the lock and unlocks signals checked for any water damage.If any damage is found it will need to be replaced.If there is no water damage at all then you would need to have the fault codes checked to see what codes are set then those codes diagnosed to then locate and repair this fault here.It may take having the ecu/receiver replaced to resolve this fault.
