Pick Resistant

Mul-T-Locks advanced telescopic pin-within-a-pin design allows the cylinder to utilize the pick resistance of ten pins in most products.

 

As shown here each pin has its own driver and spring. 

 

Mushroom pins are used in addition to a new design which interlocks the pin and driver when tension is applied.  This makes picking more difficult – virtually impossible.

 

The new Split "D" pin from Mul-T-Lock makes opening your lock without an authorized key more difficult.
