The common issue of the key blade breaking off the key remote because of the cheap plastic was something I was dealing with, using superglue, etc.
I ended up buying a key shell with uncut keyblade off amazon (2 pack for $10 or something). I then had the blank key cut to match existing key. I then transplanted the electronic part from old remote to new one, and even kept the original back on the new shell.
Result is I have a key that isnt' flimsy or falling apart and fully stable now. The cost to cut the key was $20 so all in all not a bad deal and works perfectly.
