Some safe locks require a user ID number to be entered prior to entering the code
Why is that?
As soon as the lock has more than one code, the electronics are internally numbering the stored codes.
The lock uses this to differentiate, for example in the audit, but also to determine whether certain rights are associated with the code.
In the case of certified high-security locks with a 6-digit code, this ID number only has to be entered by the user if more than 10 codes can be stored in the lock. The reason for this is a specification in the standard that in the most commonly used lock classes; there must be at least 100,000 possibilities for each individual code.
With a code length of 6 digits, there are a total of one million possible variations (000000-999999). Each saved code takes up 100,000 of them. Therefore many lock types have 1 manager/master code and 9 operator codes (for example the Home10 series).
If the lock can store more than 10 codes, there are two options:
- either increase the length of the code (7-digit, 8-digit) or
- enter the user’s ID number before entering the code.
Experience has shown that users do not get along well with 7-digit codes. Therefore, we prefer to use locks that require users to enter their ID. Also, because this results in a significant increase in security: For each individual code, there are a full million variations available. That is 10 times as many as the 100,000 variations required by the standard.
