Sim Card tray from Oppo A83 stuck in Oppo A73

Hello, I have recently recieved my mum’s old OPPO A73 and when trying to put my SIM card in I have accidently put my OPPO A83’s SIM card tray into my mum’s OPPO A73! The key wouldn’t work and I have used tool kit to try and pop the cover off but that wouldn’t work and I’m afraid it might damage the tray.
