Hi @Dipteshoza,
Welcome to the Bunnings Workshop community, it is fantastic to have you with us.
I would suggest googling the model number of your garage door motor and finding the manual.
It should give you details on what remotes are compatible and how to go about reprogramming them.
I believe this Merlin 4 Button Remote Control Key Ring is compatible.
Let me know if you have any further questions.
