Bench Evaluation and Custom Module Job Guide (2026) — 95 Dollars

Who this is for

This guide is for anyone holding a module they cannot easily categorize and asking a simple question: what is wrong with this, and is it worth fixing. That includes the independent shop with a part that is not on any standard repair menu, the mobile locksmith who pulled an oddball module and wants a second set of eyes, and the owner who has been told a module is bad but wants to know whether it can be saved before paying for a new one.

The bench evaluation exists precisely for the cases that do not fit a fixed-price service. If you already know the job, a clone, an unlock, a key program, a receiver repair, you should order that service directly. But when the answer is genuinely unclear, a 95-dollar evaluation buys you a read, a diagnosis and an honest quote, and that fee is credited toward the work if you approve it. Auto Module Lab is in Arlington, Texas and works nationwide by mail for customers across Dallas, Houston, Austin, San Antonio, Miami and beyond.

In short, this is the front door for uncertainty. It turns "I have no idea what this needs" into a concrete plan and price.

What a bench evaluation actually is

A bench evaluation is a paid diagnostic performed on the module itself, away from the vehicle, on the bench. We power the module, communicate with it, read its memory where possible, and assess its condition and its contents. From that we form a diagnosis: what the part is, what is wrong with it, and what would be required to fix it.

This is fundamentally different from ordering a known repair. With a defined service you are buying a specific outcome at a fixed price. With an evaluation you are buying information, the diagnosis and the quote, because the right outcome is not yet known. That is why it is priced as a flat diagnostic and why it is honestly described as a diagnostic rather than a guaranteed fix.

Bench-level diagnosis is increasingly valuable because vehicle electronics are increasingly complex. Modern vehicles run dozens of electronic control units, with premium models topping 100, per McKinsey, and a growing share of warranty and repair effort traces to those electronics rather than to mechanical parts. When a module is unusual or the failure is unclear, a focused bench read answers the question faster than guessing.

When an evaluation is the right call

Situation	Why an evaluation fits
Module not on our standard service list	We confirm what it is and whether we can work it
"Is this even repairable?"	A read tells us if the memory and board are recoverable
Shop or locksmith with an oddball part	A second-opinion diagnosis before committing
Conflicting diagnoses on the car	Bench isolation removes the vehicle's variables
One-off or custom module job	We scope the work and quote it accurately
Unknown failure, multiple suspects	The read narrows it to the actual fault

If your case looks like one of these rows, the evaluation is the correct starting point rather than ordering a fixed service on a hunch.

What we can determine on the bench

A bench read tells us a great deal about a module's condition and contents. On most modules we can establish:

• Whether the module powers up and communicates. A board that will not power or talk is a different problem from one that runs but misbehaves.
• Whether the memory is readable. Many failed modules still have readable flash and EEPROM, which is what makes recovery, cloning or repair possible. A read confirms it.
• What identity and configuration data the module holds. VIN, immobilizer data, coding and configuration where present, which tells us how the part relates to a vehicle.
• Whether the fault is the board or the data. A hardware fault, a failed driver or a damaged processor is a different fix from a data or security problem.
• Whether a known service applies after all. Sometimes an evaluation reveals the part is a candidate for one of our standard services, in which case the evaluation rolls straight into that work.

From those findings we form the diagnosis and the quote. The seed-key security model these modules use, defined in the ISO 14229 Unified Diagnostic Services standard, is part of what the bench read navigates, which is why a structured evaluation beats trial and error.

What we cannot determine on the bench, stated honestly

A bench evaluation is powerful but it is not omniscient, and being clear about its limits is part of doing it right:

• Faults that only appear in the car. A problem that depends on the vehicle's wiring, network, sensors or other modules may not reproduce on an isolated bench. The evaluation diagnoses the module, not the whole vehicle.
• Intermittent failures that will not reproduce. A fault that only shows up occasionally may not appear during the evaluation window, in which case we report what we found and what we could not confirm.
• Damage that destroys readability. A board so badly burned, shattered or corroded that nothing reads cannot be diagnosed beyond "unreadable," and we will say so plainly.
• Guaranteed repairability. An evaluation tells us what is wrong and whether a fix is likely, but it is a diagnostic, not a promise. Some modules turn out not to be economically or technically repairable, and the honest answer is part of the deliverable.

We would rather set this expectation up front than have you believe a diagnostic is a guaranteed cure. The 95 dollars buys a thorough read and an honest assessment, including the assessment that a part cannot be saved.

What an experienced bench tech looks for

"Half the modules that land on my bench were never broken the way the customer was told. A scan tool in the car points at a code; a structured bench read tells you whether it is the board, the data, or something upstream the module is only reporting. That distinction is the whole job, and you cannot make it by guessing from a fault code."

That discipline is also why credentialed, accountable bench work matters on security-related modules. The National Automotive Service Task Force (NASTF) operates the Secure Data Release Model that vets locksmiths and repair specialists before they can access key, PIN, and immobilizer data, which is exactly the kind of proof-of-ownership and accountability framework a legitimate bench evaluation operates inside.

How the quote and credit work

The economics of the evaluation are designed to be fair. You pay 95 dollars for the diagnostic. We read and assess the module and send you a quote for the recommended fix. If you approve that work, the 95 dollars is credited toward it, so the evaluation effectively becomes a deposit on the repair. If you decline, you have still received a real diagnosis and a quote for what it would take, which is information you did not have before.

This structure protects both sides. You are never paying for a guess, because the quote is based on an actual bench read. And you are not overpaying for diagnosis on a job you go on to approve, because the fee folds into the repair. For a shop or locksmith deciding whether a part is worth the customer's money, that clarity is the whole point.

The mail-in process, step by step

The evaluation runs on the same mail-in flow as every other bench service.

1. Pay and start your order. Begin on the bench evaluation service page. The flat diagnostic fee is 95 dollars.
2. Ship the module to the bench. Mail your module to Auto Module Lab, 1168 W Pioneer Parkway, Arlington TX 76013. Pack it protected against static and impact, and include your order details and a note of the symptom.
3. 24-hour bench turnaround. Once it arrives, we read the module, diagnose the fault, and prepare your quote, with a 24-hour bench turnaround on the evaluation itself.
4. Quote, then approved work. We send you the diagnosis and a quote. If you approve the fix, the 95 dollars is credited toward it and we complete the work. Return shipping is a flat-rate tier you pick at checkout (from $14.95, or overnight $74.95) and covers the trip back when your module ships out.

That is the loop: pay the diagnostic, ship the module, we read and quote in 24 hours, and the fee credits toward whatever you approve.

What to ship

Because an evaluation is about an unknown, the context you provide matters as much as the part. Include:

• The module in question. Send the actual module you want assessed. If you are unsure which box it is, send a photo first and we will identify it.
• Your order details. The order number plus the vehicle year, make and model where known, which helps us place the part and interpret its data.
• A clear note of the symptom and history. What the car did, what was already tried, and any diagnoses you have been given. The more we know, the more precisely we can target the read.
• Any related context for a custom job. For a one-off or custom request, describe exactly what you are trying to achieve so we can scope it accurately.

You generally do not need to send keys or other modules for an evaluation, but if your custom job requires them, we will tell you before you ship. When in doubt, contact us first and we will confirm exactly what to send.

What this service does NOT do, stated honestly

• It is not a guaranteed repair. This is a diagnostic. It tells you what is wrong and what a fix would cost. Some modules turn out not to be repairable, and that finding is a valid, honest outcome of the evaluation.
• It is not whole-vehicle diagnosis. We evaluate the module on the bench. A fault that lives in the car's wiring, network or other modules may not show here, and the evaluation is not a substitute for in-car diagnosis.
• It does not cover emissions defeats. We do not delete or defeat emissions controls under any service, including a custom job. Tampering with emissions equipment violates the Clean Air Act, which the EPA enforces with civil penalties.
• It does not promise a part is salvageable. If a board is destroyed, the honest answer is that it cannot be recovered, and you will get that answer rather than a charge for impossible work.
• It is not a free quote. The 95 dollars pays for a real bench read and diagnosis. The value is the information, which is why the fee credits toward approved work rather than being waived.

If any of these limits change your decision, that is exactly the kind of thing the evaluation is meant to surface before you spend more.

Price versus guessing or the dealer

The alternative to a structured evaluation is usually guessing, throwing a new part at the problem, or paying a dealer to diagnose in the car at full shop-labor rates. Repair labor has been climbing for years; the U.S. Bureau of Labor Statistics tracks motor vehicle maintenance and repair in the Consumer Price Index, and diagnostic time at a dealer adds up quickly.

Path	Typical cost	What you get
Auto Module Lab bench evaluation	95 dollars, credited toward repair	A real diagnosis and a quote, fee applied to approved work
Dealer in-car diagnostic	150-250+ dollars, often not credited	A diagnosis, usually steering toward a new programmed part
Buy a new module on a guess	Part cost plus programming	A gamble if the module was not the real fault
Trial-and-error parts swapping	Open-ended	Time and money with no guarantee of finding the fault

Against any of those, a 95-dollar bench evaluation that credits toward the fix is the disciplined choice when the problem is genuinely unclear. It converts uncertainty into a number and a plan.

Frequently asked questions

Is the 95 dollars wasted if I do not approve the repair?

No. You still receive a real diagnosis and a quote for what the fix would take, which is information you did not have before. If you do approve the work, the 95 dollars is credited toward it, so it functions as a deposit.

What if you cannot read or diagnose my module?

If a board is destroyed badly enough that nothing reads, we will tell you honestly. The evaluation is a diagnostic, and "this cannot be recovered" is a legitimate, useful outcome rather than a failure on your part.

My module is not on your standard service list. Can you still help?

That is exactly what the evaluation is for. We read the part, determine what it is and what is wrong, and tell you whether we can work it and at what price. Many oddball parts turn out to be perfectly workable once they are on the bench.

I run a shop. Can I send you a customer's part for a second opinion?

Yes. Shops and locksmiths are a core audience for the evaluation. A bench read isolates the module from the car and gives you a clear, independent diagnosis to take back to your customer.

Does the evaluation diagnose problems in the car too?

No. We diagnose the module on the bench. A fault that depends on the vehicle's wiring, network or other modules may not reproduce in isolation, so the evaluation is not a whole-car diagnostic.

How long does it take?

The bench turnaround on the evaluation is 24 hours once the module arrives. The rest is shipping time each way, which depends on the carrier and your location.

Can I describe a custom job before I ship?

Yes, and you should. For a one-off or custom request, contact us first and describe what you are trying to achieve so we can confirm the evaluation is the right path and tell you exactly what to send.

The bottom line

When you cannot tell which service a module needs, when the part is not on a standard list, or when you simply need to know whether something is repairable, the bench evaluation answers the question. For a flat 95 dollars we read the module, diagnose it, and quote the fix, and that fee credits toward the approved work. It is a diagnostic, not a guaranteed repair, and that honesty is the point: you get a real answer, including when the answer is that a part cannot be saved.
