How to replace the Microwave Key Pad

The numbers and letters on the key pad are coming off, Ge says it’s not a manufactures defect so I would like to replace it. I think the part # for the key pad is 1654? is that right? Is the procedure the same as the one previously posted for Model JVM1450Ba01? I’m not sure if it can be changed from the out side while it is installed in the wall or do I have to remove it? Hopefully the entire top and side covers don’t have to come off. Thanks in advance for any help you can give me.
