UPVC Cylinder lock refuses to come out

[Yanni]

I am trying to replace this cylinder and don’t seem to be able to. I have done on all other UPVC doors in the house but this one refuses to come out is a new door only one year old. The tenant replaced the keys.

I can turn the key ok and it locks fine.
I have even removed the handle.

Could it have another grub screw or something that stops it as it’s not the usual remove a screw turn the key slightly and the lock is out. Puzzled.

Pull it out from the front outside then, it has an anti snap shield outside so it won't allow the barrel to slide in

Key needs to be turned to allow the internal lever to align for removal , a few mm wrong in either direction will prevent it moving.

1. Pull Out the Cylinder - Turn the key while apply slight pressure to the opposite end of the cylinder. As you do so the cam will line up with the rest of the lock and you will be able to slide the cylinder out towards yourself. The key usually needs to be turned approximately 25° clockwise or anti-clockwise.

I do wish people would hold their phone landscape when recording videos that will be posted online and viewed in a landscape video player, on a landscape screen

Ok mistery solved the cylinder had a little grub screw that wouldn’t let it out. I had to remove the two hex screws to remove the Sbd plate as it would not otherwise remove it either from the front or from the back.
