Ok, the barrel of my patio door lock decided to explode on the back
door in a shower of small pins and springs.

Being the keen DIY'er that I am, I though, 'how difficult can it be' ?

AAgghh

Right, for anyone in the know it's a "Adams Rite" lock, and looks to me
to be a '4036 screw in cylinder'

Markings on the lock mechanism are on one side

3 80 1 1/8
and the other
4 80 1 1/8

so a few questions

1) Does anyone have an old (70's 80's from the look of things)
aluminuim patio door with a couple of these on ?

2) Or a source of cheap spares

3) Or exactly how the lock barrel actuates the lock mechanism, I can't
for the life of me see how it does it, as the barrel end doesn't engage
the slot in the lock actuator, and there's no pins etc that I can see
to move it ?

4) A possible complete replacement

5) Or if there's a decent locksmith in the North Hampshire area ;-)

I've got secondary locks on the door, but they're not all that, so i've
got a bit of grace period, but not much.
Any advice appreciated.

Cheers,

Paul.

If it's an Adams Rite it will probably be two seperate screwed cylinders
the same as on many aluminium shop doors though I've yet to see one on a
domestic door.
Do they have a small cam on the inside face that activates a hook bolt that
catches in the door frame?.
Very easily removed & replaced also manufactured by many other brands, Yale
Union Evva etc.
Having said all that, there are many variations in Adams Rite locks, same as
Yales etc.
Regards.
