CRL common mistakes
CRL · Understand the traps and how to avoid them.
Assuming possession proves authority
A requester can possess an item without authority to change access.
What to do instead
Establish authorization for the specified property and agreed work.
Using any similar-looking blank
Profiles and locating references can differ.
What to do instead
Match the actual keyway, dimensions and manufacturer information.
One key stop for every design
Tip-stopped and shoulder-stopped keys use different references.
What to do instead
Identify the actual key type before interpreting dimensions.
Equating theoretical and usable differs
Manufacturer constraints and key-system design remove combinations.
What to do instead
Calculate the stipulated model and separately assess practical restrictions.
Confusing entry control with egress
A secure exterior side does not define inside emergency operation.
What to do instead
Verify the complete approved door behavior under relevant conditions.
Replacing parts before diagnosing alignment
Door position, wear and supply faults can produce similar symptoms.
What to do instead
Investigate the complaint and connected components first.
Applying a universal closer setting
Door mass, hinges, seals and equipment differ.
What to do instead
Use the actual instructions and verify the required operation.
Changing key access without updating records
Unrecorded issue or permissions can undermine the key-control design.
What to do instead
Maintain the authorized schedule, issue history and completed service record.
