How do I get in my house?

[C locked]

The whitco part number for the 5 pins cylinder is W840700

And the correct depth for the latch is 17mm

To change the cylinder
Lock the handles by depressing the deadlatch pin
Emulating a door closed in frame
And then turn the key to lock the handles
Undo the silver screw in line with the cylinder from on the edge of the door
Remove the old cylinder

To fit a new one do the reverse

you have the tasman mk 3 and if as you say you have the 3 point (multipoint) latches
I bet that the holes in the frame for the latch to strike into that they are not deep enough
Incorrect installation

And the gap between the frane and door it too loose for the deadlatch latch pin(the small latch) doesn't properly hit the strike plate

Well, I suppose it is now too late to complain to the door people. Anyway, I doubt they are capable of fixing it.

Please post reply of what the problem turned out to be

Just thought I'd touch base, so that you won't all think that I didn't appreciate the help. I did find a locksmith that was on both the LGA or MLAA lists. Sent him an email, never got an answer. I didn't want to just phone, was worried about ending up with the apprentice again

Life sort of got hectic since then, so haven't followed up. About to do that now.

I went to Mitre 10 today to get a key cut (nothing to do with my house) They couldn't do it and recommended a local locksmith. That was about 6pm, so asked if they would be open - oh yes, he replied, they are open until 7. So, I drove there.... Closes at 5

Anyway, when I got home, I looked them up on the LGA or MLAA list and they ARE on the MLAA list. So, will go back tomorrow, and have a chat while I'm there. If they seem helpful, I won't bother chasing the other one up. They are closer to my house anyway, only about 15 minutes drive.
