Adams Rite 29-0461-03-01 Insert Cylinder W/ 2 Keys:
According to Sandra @ Adams Rite from an email from May 2012:
Hi Rich Part number 29-0461-01-01 has been replaced by 29-0461-03-01 which is the same thing.
And again in September 2013 we were told:
The item actually did come in but the warehouse didn’t know what to do because adams rite changed the part #. The part # 26-0461-01-01 is now called 29-0461-03-01 and is the exact thing you ordered except a new part# so we will be shipping it too
And the best answer came from Roget @ Adams Rite in August 2015:
Mr. Howard, The 29-0461-01-01 (which is no longer available and has been replaced by the 29-0461-03-01) used a Yale key way. The 29-0461-03-01 is the same dimension, but it uses a Schlage key way.
Please let us know if you have any questions or if we can be of further assistance.
