Universal Garage Door Opener Remote

Hi !

I have 4 overhead doors that are all operated with separate remotes.

Is there a product that can combine all 4 remotes into one remote device. Maybe even small enough for a keychain.
I found some things on amazon and google, but it does not look legit and it seems like they would not work anyways.

Can anyone help me ?

Are all 4 garage door operators the same make & model? That will help determine what may be available for you.

They are all from LiftMaster, but I'm not too sure if they are all the same model.

I would need to know what the models of each operator are.
