$550–$1,580, with an average estimate of $850 before vehicle-specific adjustments.
What to expect
Difficulty: moderate. Typical labor time: 1–3 hours.
Mechanic's tip
BCM replacement almost always requires dealer-level programming to pair it with the vehicle's immobilizer and key fobs — this is not a plug-and-play part. Before condemning the BCM, check for corrosion on the BCM connector and any water intrusion (common failure points). Intermittent electrical gremlins affecting multiple unrelated systems are the classic BCM symptom.
