They get stuck because of overactive use and dust/mold buildup. I would use an aerosol can and try to remove the filth.
That means that either your computer or you keyboard is broken. That usually leads to your computer crashing. Fix it while you still have time.
a keyboard can have 102 or 103 keys, it depends on the layout of the keyboard.
press the buttons
I researched the phone and it does have a QWERTY keyboard. They are very small buttons, but it is a qwerty keyboard. You may want to find a phone that has a slide out keyboard so that the buttons are bigger. I have big fingers so it is hard to click the small buttons.
104 normally
press the + and - buttons on your keyboard
105
You lick the keyboard then stick it IN!
Try taking the battery out of the remote. One of the buttons is probably stuck.
ok just fix it
Ctrl +
Easy , press the buttons !- Good Luck !
