Inspect the door itself
A reader cannot compensate for a door that does not close or latch consistently. Review closers, alignment, frame condition and lock operation alongside the access electronics.
Identify the existing equipment
Record controller, reader and power-supply model numbers. Existing cards and cabling may have limits that are not visible from the front of the reader.
Plan a controlled transition
Agree installation windows, temporary access, staff communications and the order doors will change over. Confirm the release and exit arrangements for each opening before handover.
Your planning checklist
- Photos and model numbers
- Daily operating issues
- Door and frame condition
- Changeover constraints
Start with the existing opening
Before choosing replacement electronics, record the door, frame, lock, reader and controller details. The service for assessing an access-control upgrade connects those observations to a proposed retrofit scope and a workable changeover.
