Easy Installation Guide
Locate the BCM—under the left dash in Silverado models or center dash in S10s. Disconnect the battery first to avoid shorts.
Swap the unit, then reconnect. For GM standards, theft relearn activates only if no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds—repeat three times.
Reset the airbag warning light by performing the ‘Setup SDM Primary Key in BCM’ with a scan tool like Tech2. Some setups need brake pedal recalibration for optimal safety—check your manual.
If unsure, consult a pro; variations exist across models like the Isuzu Hombre.
