Small Yale PKPT padlock
The body of the lock is 1.112” wide, 1.114” tall and 0.53” thick.
One side of the body has YALE MADE IN U.S.A. and the other MADE FOR U.S.
On the bottom is U T 2385. (there are 8 photos)
Does anyone have any information on this nice little padlock?
I was able to shim it to open it but could not figure how to dismantle it without damaging it so decided to try to impression the lock.
This is my first attempt at impressioning any lock so did a google search and came away with a number of tips. One of the tips suggested using copper to do an initial impression so I hunted around and found some copper strapping that I thought would fit the bill. I cut it down to rough size and then filed it to what I thought would be the proper width. Since I have a number of large Yale PKPT padlocks some with and some without keys so tried one of the keys and it inserted into the keyway of the little one nicely so I copied the profile of the slant at the tip and then went on to slowly impression my copper blank.
All was going well and then while jiggling the lock and putting tension on the shackle the lock snapped open. I locked the padlock and tried the key but it did not open without quite a bit of jiggling and then opens with a bit of a snap.
Looking back on the keyway I do not think that this lock had a flat key so does anyone know which key blank would be the correct one for this lock?
Where I would appreciate help is in some tips on how to go about fine-tuning the key so that it works smoothly. I’m afraid to file much more away lest I take off too much and then have to start all over again.
Thanks in advance for any help you can supply.
