Padlocks keyed to meet your needs
Padlocks can be purchased in keyed-alike groups, that is to say that the padlocks will all work with the same key. Padlocks can also be purchased on a master key system that will allow individual access to each padlock with an individual key as well as a master key that will open them all. Or padlocks can be purchased as single units that will not be keyed on a common key.
A number of the padlocks listed below can be specifically keyed to your home or business key, making it convenient and reducing the amount of keys you would have to carry.
