Replace patio door cylinder?

[Munzz]

Door number 1 is all good, but I can’t seem to find the screw for door number 2 to remove the cylinder. What am I doing wrong!?

Ps - It’s not behind the metal plate as pictured, I’ve already had that off.

Its behind the flying mullion screwed to the door, pop those white caps off and unscrew and you'll expose the locking mech and screw. The purpose of the flying mullion is that so the master door(the one you've already done) has something to latch against, its effectively a dog legged profile which reverses the rebate of the slave door so the master can lock against something

Great help, will give that a try tomorrow. Thank you.
