Restricted Padlocks

A restricted padlock uses a specially designed keyway that limits who can reproduce keys.
Only authorised locksmiths or the original supplier can create duplicates, protecting against unauthorised key copying.

Restricted padlocks prevent key duplication through legal and mechanical protection.
High security padlocks, on the other hand, are rated by resistance to cutting, drilling, and picking.
A restricted padlock doesn’t have to be high security, some are chosen purely for key control, especially in environments where access management matters more than attack resistance.

Partially restricted padlocks include a code card identifying the key cut. Copies can only be made using that card, but a skilled locksmith could duplicate the key if they have the right machine.

Fully restricted (patented) padlocks go further. Their keyways are legally protected, making it illegal to copy a key or blank without manufacturer authorisation. This provides maximum protection and accountability.

A patented padlock features a keyway protected under intellectual property law. This means no locksmith can legally copy the key without authorisation.
Each key blank is traceable, ensuring only registered owners can request duplicates.
This legal protection is what defines a fully restricted or fully protected system.
