A phased Digilock replacement plan should group similar installations, prioritize real problems and prove the proposed replacement before expanding it. Do not replace every lock solely because its family is described as legacy, and do not assume new hardware will share the old mounting or management credentials.
Build an inventory that supports decisions
Record more than the visible brand. For each locker bank, identify the family, generation, interface, rear mechanism, door preparation and operating policy. Include photographs of representative front and rear units and note exceptions within an otherwise uniform bank.
The Digilock identification guide is the starting point for that work. Digilock’s support library separates legacy Numeris Aspire and Versa from NextLock Axis, Cue, Sola and Range. A legacy classification is not, by itself, a statement that a specific part is unavailable or that every installation requires immediate replacement.
Keep the inventory separate from confidential credentials. Its purpose is to connect locker locations with hardware and service history, not to publish codes or management access information.
Prioritize by condition and operational need
Divide the installation into practical groups rather than ranking only by age:
- Openings with unresolved faults that require authorized assessment.
- Working locks that no longer match the intended storage policy.
- Installations with uncertain identification or missing documentation.
- Working, documented groups that can remain in service while other work proceeds.
A report that a lock “often fails” needs context. Check whether the recurring issue concerns the lock, door alignment, credentials or a maintenance procedure. Obtain support advice before making replacement the default answer to an unverified fault.
Also consider how much disruption each area can tolerate. A locker bank serving a continuous operation may need temporary storage arrangements even when only part of it is being changed.
Ask for compatibility confirmation, not a visual match
For a legacy Numeris Aspire or NextLock Range bank, submit the exact installed details with the replacement inquiry. Ask whether the proposed hardware requires a different door preparation, strike, pull or rear clearance.
Confirm the management implications separately. A replacement that physically fits is not necessarily compatible with existing keys, credentials or software. If old and new units will coexist, document which resources serve each group and how authorized staff will distinguish them.
Do not substitute current-family instructions for legacy documentation. The correct guide needs to follow the installed hardware throughout the transition, including any unusual Sola or Versa variants in the same facility.
Use a pilot with clear acceptance criteria
Choose a representative opening after the manufacturer or supplier confirms the proposed configuration. Test fit, normal user operation, approved staff assistance and service access. Include the people who will manage the lockers, not only the installer.
Write the acceptance criteria beforehand: the door closes correctly, the intended credential works, the storage policy is supported and staff can identify the right instructions. Record remaining questions rather than treating a single successful opening as approval of every different door in the building.
After approval, schedule a manageable bank of lockers and reconcile the inventory immediately afterward. Preserve removed hardware only where authorized staff have established a useful service or recovery purpose; do not mix unidentified old parts into an active spare pool.
Plan spares around the actual installation
There is no universal spare percentage appropriate to every site. Consider the number of distinct configurations, their service history, available support, confirmed supply arrangements and the effect of taking an opening out of service.
Ask the supplier which parts or complete units are appropriate to hold and how they should be stored. Identify spares by confirmed configuration, not merely “Digilock.” A spare that cannot fit the affected door or work with its management setup offers little practical help.
Request a phased-replacement quote with the inventory groups, photographs, quantities for the first phase and unresolved compatibility questions. Confirm current availability and the proposed replacement path before committing to later phases.
Phased-replacement questions
Does “legacy” mean a lock is discontinued?
Not automatically. Use the manufacturer’s exact classification and ask about the particular model or component. Do not infer current availability from the legacy label alone.
Can we mix old and new Digilock locks?
A phased project may retain different groups, but compatibility and management must be confirmed. Similar appearance does not establish shared credentials, mounting or instructions.
How many spare locks should we order?
Base the decision on the confirmed configurations, operating impact and service arrangements. Avoid a generic percentage without considering the site’s actual mix of hardware.
Should an entire locker room be replaced after one fault?
Not without investigating the cause and condition of the remaining installation. Use documented findings to decide whether targeted service, a limited replacement or a broader project is appropriate.
