Not obvious how to remove broken button. 
SOURCE: Door will not open. Button release does not release the door latches.
The plastic lever release is more than likely broken. You can order the part from

It's about twenty dollars.
SOURCE: How do you get the front panel off to replace the door release latch
You will need a T20 x 100mm Torx Wrench to remove the 4-5 security screws that hold the top "hood" on the microwave unit. I could not find the wrench at Home Depot or Lowe's but it was available at Harbor Freight tools. Its also found easily on the Internet. Its about $10 for a set of 5-10 different sizes.
After removing the screw, and removing the hood, the rest is pretty simple. The left side (looking from the rear of the unit) will be completely exposed now. Be careful not to touch the Magnetron, Transformer, and other wiring to the unit as everything is on this left side.
You will have to unscrew one screw on the top of the control panel that attaches it to the main unit. Once that screw is off, you have to carefully disconnect 3 electrical connectors on the circuit board, then you just have to pull the control board up and out, as there are a couple of latches on the bottom that hooks it onto the frame.
If the microwave door won't open the open lever might be broken. This part can be replaced separately.

If the microwave door won't open the door latch might be broken. The door latch is inside the microwave. The door hook, which is part of the door, engages with the latch to keep the door closed during operation. If the door latch or actuator breaks the door may not open.

If the microwave door won't open the door hook might not be releasing properly. The door hook is installed inside the door and normally releases when the door is opened. The hook is made of plastic and will break over time. When this happens it will need to be replaced, it can't be repaired.
