Court Registrar Danny Buaya granted the remand application by the Investigating Officer (IO) of the case, Inspector Shreethan.
The mother and father, in their 20s and 30s, were represented by counsel Ram Singh, YS Lo and Timothy Daut.
According to Ram, the police applied for a seven-day remand for the couple.
Ram, however, applied for police bail to be granted to the parents, saying his clients had given fully cooperation to the police in looking for their missing child.
He said it did not serve any purpose to detain the parents as they had done their level best to locate their child.
Ram also said the parents had surrendered themselves to the Karamunsing police station at 9pm on Wednesday together with a friend who was also remanded with them.
In the meantime, Ram said the parents have appealed for public assistance to locate their son.
The child went missing from his father's Toyota Hilux, which was stolen near a petrol kiosk in Kg Air on May 9.
The vehicle was recovered several hours later without the boy.
