thanks for the reply.
but, the screw that lines to the lock is a very small one, not the long one that goes through the eruolock. behind this screw is another metal peice which i cant remove. there is no screw in this metal peice.
I cannot remove the metal door strip to replace a yale euro lock. its has double lockinf features, i removed all screws but the middle part doesnt come out of the door frame. theres a metal peice stopping it.
thanks
