As it isn't dangerous and pushing the buttons is a good development activity I don't want to stop her. I do, however, want to stop her changing channels during an exciting time in the rugby.

To this end, I want a child-lock on the remote. Now this, although not common, is baked (I saw it on a video remote once - well actually many times, but always the same remote).

In addition to the child lock (activated and deactivated by a sequence of keypresses) I want a button on each side of the remote which when both pressed together would temporarily over-ride the child-lock. These would be easily pressed and in a position where they would be pushed naturally by an adult hand gripping the remote. This would enable little stickypaws who doesn't have the knowledge (or handspan) of an adult to play with the remote with no consequences and adults to use the remote without having to key in a code every time.

[afterthought] Actually this would also make a good keypad-lock for a mobile to stop you dialing your mother from the bottom of your sportsbag.
