What Our Nissan Customers Say
“Smart key stopped working after I replaced the BCM. Had to get it re-registered. These guys handled the whole thing by mail. Saved me the dealership trip entirely.”
“CVT was shuddering and throwing codes. Nissan dealer wanted $3,200 for a new transmission. TCM repair here was $219. Fixed the problem completely.”
“NATS light on my Frontier had it in anti-theft lockout. Shipped the ECM, had it back programmed and synced in three days. Started right up.”
Nissan ECM Repair FAQ
What is Nissan NATS and how does it affect starting?
NATS (Nissan Anti-Theft System) uses transponder chips in the key to verify authorization before allowing the engine to start. When the ECM or NATS module fails, the system locks out starting even with a valid key. We repair the module and perform NATS transponder re-registration so your existing keys work without a dealer visit.
Can you fix Nissan CVT transmission problems?
We repair the TCM (Transmission Control Module) that governs CVT behavior — not the mechanical CVT unit itself. If your Nissan is shuddering, slipping, or throwing P0700-series CVT fault codes due to a TCM failure, we can repair it. Contact us with your fault codes to confirm the TCM is the root cause before shipping.
Do you repair Infiniti ECMs?
Yes. Infiniti vehicles share the Nissan platform, so our full ECM, TCM, and NATS repair capability applies to all Infiniti models including Q50, Q60, QX60, G37, and FX series.
Will the repaired ECM be plug-and-play?
Yes. We program the ECM to your VIN and re-register the NATS transponder data before shipping it back. Most vehicles are plug-and-play after installation.
How long does Nissan ECM repair take?
Most repairs complete in 48–72 business hours from receipt. Rush 24-hour service is available for an additional $75–$100.
