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 note: if you live in a co-op, you may find that it is not possible to program this remote control. Please ensure that the receiver has not been locked by the management. If it is, then it is not possible to program additional remote controls. This remote control is not compatible with the black model Aprimatic TX2M .
