Flat keys for PTPK padlock

I have a question regarding flat keys for PTPK padlocks that I hope some of you may be able to answer.
The Yale PTPK padlocks take the Ilco 1031 flat key that fits the keyhole fairly snuggly.
I have 2 Sargent PTPK padlocks that I would like to make new keys for.
I have disassembled them and they are both 5 pin and the keyway is larger in height than the Yale so the 1031 key fits quite loosely. There is a lot of play from top to bottom in the keyway when the key is inserted and the 5th pin is at the slant of the key blank.
I assume that the 1031 would not be suitable for the sargent padlock so does anyone know which key blank would be the proper one for the sargent padlocks.
Thanks

The last time I know that Ilco has two differ keys for these PTPK. This one it : ILCO 1239, D/L 639, Taylor T113. The width .285"-7.2mm, Thick .004"-1.0mm. I don't know if this on market or not.....Timothy.....

Thanks for the reply Timothy.
As far as I can see the 1031 and 1239 are the same size.
The 1031 is nickel silver and the 1239 is flat steel.
I have a FULTON PTPK padlock made by Slaymaker with the original key that is .330" wide and .055" thick that fits the Sargent keyway nicely so that would be the key blank that I am looking for.

OK! do you have key blank number for it. I just found a web site to get the 1239 but you already has it...https://www.worthpoint.com/worthopedia/locksmith-ilco-1239-flat-steel-blank-1868185104......Timothy......

Just a little more information that I found. Not sure if this the kind of PTPK you have but I'm sure the key blank will fit No. 5559. I know they don't make it any more....Timothy.......

I believe the Sargent 5559 blank is l-o-n-g discontinued but I found an Old Ilco blank that is probably the equivalent, 1248S which is .335" wide x .050" thick; also discontinued but another possibility, see thumb nail attached.

Where you findthe 1248S Blank at I don't see it in the ILCO Catalog....??..Timothy.....

perhaps cut down a flat steel k ey ? i just used my last blank on this sargent. Pete is correct on the blanks and i doubt you will find one. This blank had a 251E on it and i do not know who made them.

forgot info
the 1031 is nickel silver and 1239 is plated steel, these are not wide enough ,but were available from north carolina thru distributor last year .

would something like this work ? the stop is very short,and you might have to file the bow near the stop ?

Timothy, note that I said Old Ilco, can be found in:

1. 1950 Ilco Cat. 13G, Pg. 30
2. 1949 Ilco Cat. 12B, Pg. 30
3. 1947 Ilco Cat. 12A, Pg. 29
4. 1941 Ilco Cat. 12, Pg. 163
5. 1936 Ilco Cat. 11, Pg. 64
6. 1932 Ilco Cat. 10, Pg. 56
7. 1930 Ilco Cat. 9, Pg. 43

In 1941 the net price was $4.80 per gross.

Nathan, 251E is a Keil number, crosses to 1248 Old Ilco and 2790C Graham all of which are obsolete. Old Ilco 1248 and 1248S are both .335" x .050" but the former is steel while the later is nickel silver. Thus we now have three more possibilities for that old Sargent push padlock blank.

thank you,Sir,i will make a note on these #'s
thank you Pete

Thank you all for your input.
I was thinking that it might come down to making my own key blank.
Just need to find a satisfactory blank to start with.

Mailed this morning,enjoy

Now that brings back memories! Many of the men I trained under spoke of blanks by the dozen and there were hundreds of boxes of blanks marked that way. I cut many thousands of keys on Graham and Keil blanks.

Thank for information I was looking at the ILCO #60. I may have one at home in box somewhere but don't think going into all that......Timothy....

I received the key that you sent in the mail yesterday.
Thank you very much.
Made a key for one of the five pin sargent locks.
There is almost no cut on the 5th pin.
Needed to make the modifications that you suggested and the new key works well.

Meant to say that there is almost no cut in the 1st pin not the 5th pin.

not being a sargent bow made me wonder ? Glad they worked. i seen a pat date of 1912,did not find them until 1936 catalog.
enjoy.

pat 1,029,942 to albert a page assigned to sargent&co

They are in the 1922 and 1926 catalogues that I have seen online.

had hard time shimming this flat key sargent,found one steel pin in #1 and long brass pin in #2 hole ,then 3 top and bottom pins with 3 springs ?
Attachment 19667Attachment 19668Attachment 19669makes you wonder ? Had to bounce the first 2 pins to get the shim past them,no springs and edge of shim just caught on both as it went in.
