Remotes with the same frequency are not compatible, if the shape, the color of keys, color of the box is different. This applies even if they are from the same brand. They do not have the same electronics!
Please open your remote control and verify that there are programmable switches inside. If there are none, then please check the model number written on the back. If you see Be Good XS3 then the correct model is the SEAV Be Good XS3 White. If you see Be Good RS3 then the correct model is the SEAV Be Good RS3 White .
