Renault Scenic X Reg Boot Button permanently depressed?

Hi I really hope someone can help! My Renault Scenic automatically locks when I hit roughly 4mph and will only unlock everything once the driver's door has been opened. Coming home today my children got out of the back of the car first (which only unlocks their doors, not the boot etc) and tried to open the boot. As they were pushing the button in I opened my door which unlocks everything and now the boot button is stuck pushed in. I really can't afford to take it to a garage being a single mum and I can't really afford to spend loads on new parts either so I was wondering if there was a simpler solution to this? Any advice or help greatly appreciated. Thank you
