Bumpkeying is one solution to a persistent stuck up pins

[yono]

recently, i was figuring out of how to open an almont padlocks that has been left for nearly of disposal stage due to the fact that they been use in an open area unmaintained for a long long time.the pins were colored like sand, and really stuck up. soaking on lubricant, WD40, doesn't solve it. the Master, the change key doesnt work. the last option goes to my mind were drilling the pins/spring cover. suddenly i thought, why not try bumpkeying first? there is nothing to lose, but something will be gained (saving time if it does work) and to my surprised it does work in less than 20 seconds each, I opened 9 out of 10 of these garbage. try this in the same situation..were the pins were clogged up, or the master wafer mispositioned, or the pin spring tip caught up with the top pins and clogged it. with this, you will be able to open the lock cylinder and rectify the problem. regards.

I find that often times a good sharp rap to the spring side of the lock with a block of wood, or a rubber mallet whilst the propper key is inserted seems to work best, picking/bumping locks that are not in good working order can be a recipe for disaster, I have never broken a padlock by rapping on it with a section of 2x4 lumber.

I just imagined PYRO500 in the staring role of "Walking Tall" ...

I ran into a call out for a hitch mount lock that had gritted and rusted it's way to immobility. I tried WD40, and then gave up and drilled. I wish I thought about bumping or going Dwayne Johnson on it first...
