Ace type locks (like those found on vending machines, bike locks,etc....)are being opened/bypassed by utilizing a Bic 20 cent pen. The barrel of the pen with its cap removed, fit’s perfectly into the ace type lock. With very little effort or time this pen will both open and re-lock. E-mail me and I will send you a file showing how easy this can be done. Their will be impressioning marks left on the pen which will match the pins within the lock, so both pen and lock should be secured as evidence for forensic evaluation. ShatteredShield@msn.com
