Replaceing broken lock for double glazing

[technium]

Hi

Our key wouldnt work in our door anymore so took it apart and found that a cog inside had been stripped, can I just replace a cog or will I need to buy the whole lock.

If you look at this pic you can see where the cog is broken.

The lock itself is riveted to a long bar which goes up the lenght of the door so if i need a new lock would i need to buy the whole lot including bar as it wont come off? heres a pic

Next thing is where can I buy a lock like this and as there are loads od different ones is there a specific name for it?

any help appreciated.

thanks

Should be a serial number somewhere, have you look at this company?

Hi

There doesnt seem to be any markings on it at all, no name and no number.
Where is it likely to be ?

Thanks

Might be an idea to buy a new lock because the cog wheel are normally compressed in by a special tool but take it down to your nearest dg unit spares/parts shop to see what they say.
