Why it matters for VP4 radios:
• Radio and BCM are paired during manufacturing
• Disconnecting BCM can trigger anti-theft code request
• Swapping VP4 radios requires BCM reprogramming at dealer
• BCM stores the radio's VIN pairing information
Common BCM scenarios requiring code:
• BCM replacement or repair
• Electrical fault requiring BCM reset
• Installing radio from different vehicle
The unlock code is tied to the radio serial number, not the BCM or VIN.
