Patio Door Lock

I apologize, my junior locksmith took a lot of pics of the lock itself and none of the door. I expect I will need to send him back but figured I'd try you wizards first. As you can see it has a Euro cylinder and on the strike the letters "16DGE" and on the mortise body it says "4MGE". I tried googling those to no avail. Please let me know if you recognize this... if not I will send him back for more info. Thank you! -Joe

Thank you, this seems to be correct! I will gather some more info and order the parts. Thank you! -Joe
