How to use bump key to foil pin tumbler locks and impression
Also all weather aluminum foil tape works amazing with bump keys but the time it takes to impression increases dramatically because of how stiff the tape is and if you have a lock with strong springs behind the pins then i would really recommend it because you can literally put the key in and out of the lock 2-4 times sometimes (without even using a guide tool to lift the pins lol) and it will still work as a working key so the strength is higher but the time is longer so if your working on a time frame where failing is detrimental issue then i dont recommend it until you have practiced a lot and know what your getting yourself into because as i show in the video at end i make an almost perfect copy using regular kitchen aluminum foil but i miss one pin. Yet the time before the video i used weather tape and had a working key i removed and reused 3 times before it stopped working (without using a guide tool to re insert or remove the key)
Enjoy please let me know what you think!
