Hi. This is an interesting one.

So i get in to start my car, turn the key, turns over and starts, but as soon it start's it cuts out. all the lights start to flicker.

But when I press the key with some force inwards as far i can and turn it, it starts normally.

Any idea what would be the problem? Does any one had this problem before?

Your ignition switch is about to fail !!

ok. tnx. will check it out.
