Nissan and Infiniti Module Programming Cost in Plano (2026)

A Nissan or Infiniti that needs a module programmed usually arrives at that point the hard way. A shop has replaced a body control module, a used engine computer came out of a salvage yard, or a CVT got a new control unit and now the car cranks without starting, throws a security light, or refuses every key you own. The part is in the car. What is missing is the conversation between that part and the rest of the vehicle.

Quick Answer

As of September 2026, Nissan and Infiniti module programming in Plano typically runs $150 to $450 per module for the programming itself, with a body control module job that has to be configured to your VIN and re-married to the immobilizer landing around $300 to $550 when you supply the module. Key registration after module work usually adds $150 to $350, and if no working key exists once the module is swapped, expect $320 to $700 or more for the full job. The module part is always priced separately.

Those are ranges on purpose. No honest technician can quote a Nissan module job to the dollar over the phone without the VIN, the exact module, and whether a working key still exists. The rest of this page explains what moves you from the bottom of each range to the top.

Why Nissan Module Work Is Its Own Category

Most Nissan and Infiniti vehicles built in the last twenty years run the Nissan Anti-Theft System, usually shortened to NATS. It is the immobilizer: the system that checks the chip in your key before it allows the engine computer to fuel and fire. On older turn-key cars the immobilizer logic lived in a separate unit near the steering column. On most Nissans from the late 2000s forward, and on nearly every push-button Nissan and Infiniti on the road today, that logic sits inside the body control module, and the Intelligent Key functions are either inside the BCM or in a dedicated Intelligent Key unit on older generations.

That design has one practical consequence for your wallet: the BCM and the ECM have to trust each other, and both have to trust your keys. Replace either module and the trust chain breaks. The car does not know the new module, the new module does not know the car, and neither knows your keys.

Nissan secures that trust with a PIN. On many platforms the PIN is derived from data on the BCM, and it is the gate a technician has to pass before the immobilizer will accept a new key or a new partner module. That PIN step is why "BCM PIN retrieval" shows up as its own line in the table. On some jobs it is quick. On others it is most of the session.

Cost by Module, Explained

Body control module (BCM)

The BCM is the most common Nissan module we are called about, and it is the one tied most tightly to your keys. BCMs fail from water intrusion under the dash, from voltage spikes during a jump start, and occasionally from plain age. Shops also replace them while chasing an electrical fault that turns out to be something else.

When the BCM is replaced, it arrives either blank or configured for a different car. It has to be configured to your VIN and your vehicle's options, and then the immobilizer has to be re-established with the engine computer and your keys. On a used BCM from a salvage yard, the job can also include clearing the previous vehicle's data before any of that can happen.

That is where the $300 to $550 range for a supplied BCM comes from. The low end is a straightforward replacement on a common platform like an Altima, Sentra or Rogue with keys present. The high end is a used module, a push-button Infiniti, or a car where the previous module's data cannot be read.

If you are chasing an electrical symptom rather than a no-start, our longer explainer on BCM programming walks through what the module actually controls before you buy one.

Engine control module (ECM)

A replacement ECM on a Nissan needs two things: the right calibration for your engine and transmission, and a marriage to the immobilizer so it will fuel the engine when your key is present. Skip the second step and you get the classic post-swap symptom - the engine cranks, may catch for a second, and dies, with the security light flashing.

The $200 to $450 programming range covers configuring the ECM to your vehicle. The $150 to $350 immobilizer marriage is often done in the same visit and priced together. A used ECM from another vehicle adds work, because it still believes it belongs to its donor car.

The same logic applies across makes, and our page on PCM replacement and VIN programming covers it in more depth for readers comparing a Nissan quote against a Ford or GM job.

Transmission control module (TCM), including CVT units

Nissan leaned heavily on continuously variable transmissions, and the CVT control module is not a plug-and-play part. On many Nissan CVT applications the transmission's own calibration data has to be carried over or written to the replacement control unit so it drives the specific valve body and pulleys it is attached to. Get that wrong and you get harsh engagement, shudder, or a transmission that drops into a protective mode.

The $180 to $400 range covers flashing and configuring a replacement TCM. It does not cover diagnosing an internal CVT failure. A worn CVT belt or pulley is mechanical, and no amount of programming fixes it. If you are not sure which one you have, read our TCM programming guide before paying for a module.

Intelligent Key unit and key registration

On many older push-button Nissans, a separate Intelligent Key control unit handles the fob. On newer models the BCM does it. Either way, after most module work the keys have to be registered again, which is the $150 to $350 line. Registration usually means every key you want to keep has to be present, because registering one key often clears the others.

What Actually Changes the Price

Whether a working key survives the job

This is the single biggest swing. If a working key exists before and after the module work, the technician has a trusted credential to anchor everything to. If the module swap happened because every key was lost, or the car arrived from auction with no keys, the key code and the immobilizer registry have to be rebuilt from vehicle data. That is the $320 to $700 or more line, and it is why we always ask how many keys you have before quoting.

If you are in that spot, our walkthrough of all keys lost, from VIN to a new key explains every step and why each one takes the time it does.

New, remanufactured or used module

A new module from Nissan is the cleanest programming job and usually the most expensive part. A remanufactured unit is typically sold ready to configure. A used module from a salvage yard is the cheapest part and frequently the most expensive programming job, because it has to forget its donor car first, and some used modules cannot be made to forget at all.

We will tell you on the phone whether a used module is a reasonable gamble for your specific vehicle. Sometimes it is. Sometimes the programming cost erases the savings on the part.

Turn-key versus push-button

Turn-key Nissans like an older Sentra, Versa, Frontier or Altima are generally at the lower end of every range. Push-button Nissans and nearly every modern Infiniti sit higher, because the Intelligent Key system adds another layer of registration, and parts cost more.

Infiniti is not a different system under the badge. A Q50, QX50 or QX60 uses Nissan's architecture. What changes is option content, which means more configuration, and on the larger models more modules talking to each other.

Whether an online session is required

Some newer Nissan and Infiniti procedures require an authenticated online programming session rather than an offline configuration. That takes longer, and it is one reason newer model years trend toward the top of the range.

Where the car is and when

Everything on this page is mobile work done where the car sits - a Plano driveway, an office garage in Legacy West, or a shop lot in Richardson that asked us to come finish a programming job. An after-hours or weekend call carries a surcharge that we confirm on the phone before anyone drives out.

Plano-Area Scenarios

These are the patterns we see across Collin County, described so you can recognize your own situation. They are composites, not individual customer stories.

The shop that replaced a BCM and now nothing starts. An independent shop in Plano chases a lighting or door-lock fault on a Rogue, replaces the BCM, and the car goes from a small electrical nuisance to a no-start. The fix is BCM configuration, PIN relearn, and key registration - usually the $300 to $550 line plus key registration if the keys were cleared.

The salvage-yard ECM on a Frontier. Someone in McKinney buys a used ECM to save money after a failure. The truck cranks and dies. The ECM needs configuration and an immobilizer marriage, and if the donor data cannot be cleared the part is not usable, which is worth knowing before you buy it.

The CVT control unit on an Altima. A transmission shop in Garland replaces a CVT control module and calls us to finish the configuration. That is the TCM line, and it only fixes the problem if the transmission itself is mechanically healthy.

The QX60 with one key left after a module swap. A family in Frisco has one working Intelligent Key after BCM replacement and wants two. The key registration line covers it, with every key present at the appointment.

Locksmith, Dealer or Transmission Shop?

A Nissan or Infiniti dealer can do every job on this page. The trade-off is usually towing, scheduling, and a service-department labor rate. A mobile automotive locksmith comes to the car and focuses on the immobilizer, key and configuration side.

A transmission shop remains the right call for internal CVT failures. A mechanic remains the right call when a module failed because of a wiring fault that will simply kill the next module too. We would rather tell you that on the phone than program a new module into a harness that is going to destroy it.

Common Questions About Buying the Module Yourself

Plenty of Plano owners save money by sourcing their own module, and that is fine. A few things protect you when you do:

• Match the part number, not just the model. Two Rogues from the same year can use different BCMs depending on trim and options. The part number printed on your existing module is the safest match.
• Ask whether a used module can be cleared. Some sellers know; many do not. We would rather check the part number before you pay for it than after.
• Keep the old module. Data on the original module sometimes makes the new one easier to configure, and it is your fallback if the replacement turns out to be defective.
• Do not install it and start cranking. Repeated start attempts with an unmarried module drain the battery and can store extra fault codes that have to be cleared later.

Before You Call

Have these ready and the quote gets much tighter:

1. The VIN from the dash or door jamb.
2. Which module was replaced, or which one a shop says has failed.
3. Whether the replacement is new, remanufactured or used.
4. How many working keys you have right now.
5. The exact symptom - cranks and dies, no crank, security light solid or flashing, or a transmission warning.

If the car simply will not start and nobody has touched a module yet, start with our guide on the immobilizer light staying on with no start. Plenty of Nissan no-starts are a key or antenna problem, not a failed computer.

Frequently Asked Questions

How much does Nissan BCM programming cost in Plano?

As of September 2026, configuring a replacement BCM to your VIN and re-establishing the immobilizer typically runs $300 to $550 when you supply the module, plus $150 to $350 if your keys need registering again. A simple BCM PIN relearn without a replacement runs $100 to $275.

Can a used Nissan ECM or BCM be programmed to my car?

Often, but not always. A used module still holds its donor vehicle's data. Many can be cleared and configured; some cannot. Call with the part number and the VIN before buying a used module, and we will tell you whether it is a reasonable gamble.

Will my keys still work after a module replacement?

Sometimes they do, and often they do not. After BCM or Intelligent Key unit replacement, keys usually have to be registered again, and registering one key can clear the others. Bring every key you want to keep to the appointment.

Is Infiniti module programming more expensive than Nissan?

Usually a little, because Infiniti models carry more option content, more modules, and more expensive keys. The underlying system is Nissan's, so the process is the same.

Does programming fix a slipping or shuddering CVT?

Not if the transmission is worn internally. Programming configures a control module. If the CVT belt, pulleys or valve body are damaged, the transmission needs mechanical repair.

Do you program modules at my home or a shop?

Yes. The work is mobile anywhere in Plano, Frisco, McKinney, Allen, Richardson, Garland and the rest of Collin County, including independent shops that want the programming finished on their lift.
