Mul-T-Lock Interactive+ cylinders have a special telescopic pin tumbler mechanism with internal and external pins. Both the internal and external shear lines must be aligned simultaneously in order for the plug to rotate.
The Interactive+ platform offers patented key control; pick, drill and bump resistance and utilizes dual locking mechanisms.
Interactive system combines special telescopic pin tumbler mechanism with a spring-loaded pin in the cylinder plug to produce a ‘virtual combination’ that may only be achieved when the key is inserted in the lock.
The patented Interactive keys, will only be cut on presentation of the Key Holder Registration Card.
