Front upvc door lock

I have just changed the handle and lock on my front uPVC door but the door won't lock when closed. I tried repositioning the striking plate but it only lock when I took it off. The lock works when the door is open. Do I need the strike plate? Or do I need to replace it?

"Hi Ken the keeps on the door frame need moving or the hinges might need adjusting as the door might have dropped"

"Depending on which part you have replaced (cylinder or mechanism) it could be an alignment issue or the wrong mechanism for the strike plate"

"It may be that the hooks/rollers are not all connecting into the correct place so the door will not lock it will just need adjusting to the right position cheers."

"The keeps need to be adjusted.
A locksmith can reposition the keeps."
