The 6ft-x-8 mm Heavy Duty braided steel cable provides a significantly higher cut strength, and an included dust cover protects the key chamber from the elements for a longer lasting locking mechanism. Bell offers free standard key replacement for all key locks. Follow the directions on the packaging to register your key as soon as you receive your lock and we will send a replacement if your key is ever lost. An independent lab has rated the security of this lock a 2 on a 5-point scale.
