I also ordered a genuine factory replacement case for the key fob. Apparently this is a common problem most likely stemming from a flawed design. I must warn you that there is a caveat to this replacement case if you are planning on doing it correctly. All you will receive is the case...nothing else. That means that you must not only transfer the electronics from one case to another. You must also transfer the two silver metal flanges. One side contains the emergency key, while the other side accesses the battery. There is a small spring-loaded button mechanism on the bottom center that must also be transferred. I found it extremely challenging trying to reinstall that button/spring combination on the new case.The button is used to release the key assembly from a locked position so it can be pushed back into the case. No one else seems to have mentioned that. Either everyone else had some secret to installing the tiny spring and button mechanism, or they simply left it out. With much effort, frustration, and time, my key fob looks brand new and works perfectly. Good luck.
