Question

Security problems with master keys include (mark all that apply): Master keys are easier to copy than other keys. Master keying reduces the number of useful combinations. Locks that have the master pins needed for master keys are easier to pick. Unauthorized master keys will permit access to any lock in the series.

Answer 1

- Master keys are easier to copy than other keys.

- Unauthorized master keys will permit access to any lock in the series.

Step-by-step explanation:

This is the sad reality when an individual who's unauthorized gains access to a master key, then, he may be permitted access to any lock in the series.

Also, rather trying to copy other keys, it will be far easier to copy just one key– the master key.
