Guardian Lock StyleLock Style

info icon

We offer 2 different lock styles to best suit your needs.

The Guardian 820 style has a scissor clip built right into the lock. The built-in scissor clip costs $6 more than a free-standing scissor clip, but it is perfect for situations where you need to unlock the equipment often and want the convenience of a one piece lock.

The Guardian 810 style is the economy version and does not have a scissor clip built in. This is better for equipment that does not need to be unlocked often, so you can save money when you don't need the convenience of the built-in scissor clip and can use a free standing clip. The 810 can also be used as a bullet end, or can provide a loop if the situation warrants (see 'How to attach the security cable to your equipment' for more information)

Key Options

previous key# to match (optional):


KEYED-ALIKE: When you purchase keyed alike locks, chances are you don't want a ton of keys floating around. Usually, you only need a couple of keys for authorized personnel.

You can now specify how many keys you need. The default is 2 keys. This means if you order 1 kit or order 100 kits, you only get 2 keys. But you may have 6 authorized people you want to hold on to a key. In that case, change the default number from 2 to 6 (or however many you need) and that is the number of keys you will receive. In the future, if you find you need additional keys, we will send them to you at no additional charge. (up to 2x the number of kits ordered)

MASTER-KEYED: When you purchase master-keyed locks, each kit will come with its own set of 2 keys. Your 1st order of 10 or more MK cables comes with 1 free master key. If ordering less than 10 cables, or if you need additional master keys, please call (800) 466-7636 to order.

KEYED-DIFFERENT: Each keyed-different kit comes with 2 keys per kit.
