replaced upvc lock gearbox but working reversed

[sleepydormouse]

Our upvc front door had stopped working and the locks would not engage so my husband today stripped it and replaced the gearbox (with help from a lock shop in town).

Its working well now, but you can open the door from outside without a key (unless its locked) and from inside you need to use the key to open it. This used to be the other way around.

Is there something in the gearbox which can be switced to make this the correct way round again. The latch is facing the correct way.

Take off the handle, get the split spindle and turn it around.

just tried but hasn't solved problem, thanks

Take it out of the door and put the cylinder back in the lock and try it.
Its generally the spindle or the handles that control this.

Some of the older locks I believe had a switch on the mechanism where you used a screwdriver to knock the switch and it changed it from l/p to l/ l, I think.
