Union Double Cylinder

[SnowyBoy]

Alright chaps, I bought myself a union double cylinder lock (for those double glazed back doors) to mess about with as i was getting far too familiar with one type of lock, which is unhealthy.

Just wondering what peoples thoughts are on them? I've lost my tension tool, so am as yet unable to have a go with it....but i recall having a go on one ages ago to no avail.

Any ideas what type of pin setup it has? security pins at all?

Cheers

P.s its a UNION DOUBLE EURO CYLJ2X18-SC-AA
