ALOA CMST common mistakes
ALOA CMST · Understand the traps and how to avoid them.
Treating a relocker, glass plate, or secondary locking device as an optional accessory that can be left out when reassembling a safe door, so the container is returned to service without its defensive features intact.
Candidates focus on making the lock and boltwork function and mentally file the relocker as 'extra'; it does not affect whether the door opens, so its absence goes unnoticed during a functional check.
What to do instead
Build a per-container checklist of every defensive device encountered during disassembly (relockers, glass plates, spring-loaded triggers, thermal links) and require each to be re-verified and documented before the door is closed and the job signed off.
Assuming a safe is 'just a locked box' and drilling or forcing without first identifying the lock type, boltwork configuration, and whether relockers are present.
Time pressure and the desire to show a quick opening lead candidates to skip the survey step; unfamiliar containers are treated like the last one they opened.
What to do instead
Mandate a documented pre-attack survey: lock identification, dial/spindle behavior tests, listening and feel checks, and a written hypothesis of the internal layout before any tool touches the door.
Manipulation attempts abandoned after a short sequence, or graphs/records kept loosely so the candidate cannot tell which wheel is set or which contact points were already tested.
Manipulation demands sustained concentration and structured record-keeping; under exam stress candidates rush, lose track of wheel position, and restart from scratch, concluding the lock is 'unmanipulable.'
What to do instead
Practice with a strict written protocol: log every contact point, amplify and record the readings, and set a minimum disciplined attempt time before switching techniques.
Dialing combination changes on a safe lock without confirming the change key/index procedure and then handing back a container whose combination the customer cannot open.
Candidates memorize a sequence for one lock family and apply it to a different model; they also skip the final verification open with the door open.
What to do instead
Always identify the exact lock model and follow its change procedure, and require a verification open with the door ajar (and a second verification after closing) before the job is considered complete.
Diagnosing a 'lock problem' that is actually boltwork binding, a sagging door, or a misaligned bolt, and replacing or servicing the lock unnecessarily.
The lock is the visible, familiar component, so candidates anchor on it instead of testing the whole system; symptoms like a stiff dial or hard bolt throw are misread as lock failure.
What to do instead
Follow a differential diagnostic order: test the lock in isolation, check door alignment and boltwork travel, and confirm the fault location before removing or replacing any part.
Skipping lubrication and torque specifications, over-oiling a lock, or using the wrong lubricant on the wrong component.
Candidates treat lubrication as trivial and default to whatever is on the bench; excess oil attracts debris and can gum up tumblers or lever packs.
What to do instead
Use manufacturer-specified lubricants sparingly, know which components should run dry, and include correct torque and lubrication in the service checklist.
Quoting a price or scope of work before inspecting the container, then being unable to complete the job for the quoted figure.
Phone quotes feel efficient and candidates want to win the job; they underestimate the variability of safe work and the cost of a failed opening attempt.
What to do instead
Quote inspection-based estimates with clearly stated assumptions and contingencies, and put the conditions in writing before work begins.
Failing to document the condition of the container and the customer's instructions, including authorization to open or drill.
Candidates see paperwork as overhead and rely on verbal agreements; later disputes over damage or ownership have no record.
What to do instead
Use a standard intake form capturing container condition, ownership verification, authorized scope, and customer signature before any work starts.
Opening or servicing a container without confirming the customer's legal right to it, or accepting an unverified story at face value.
Candidates want to be helpful and avoid awkward questions; ownership checks feel like distrust of a paying customer.
What to do instead
Apply a consistent ownership-verification procedure for every job (identification, proof of address or purchase, documented statement) and decline work when verification cannot be met.
Promising confidentiality or outcomes the technician cannot guarantee, or discussing a customer's container and contents with others.
Candidates improvise reassurances to close a sale and do not treat client information as confidential by default.
What to do instead
Adopt a written confidentiality commitment limited to what can actually be promised, and train the habit of never discussing client jobs or contents outside the business.
