Frequently asked questions
Do both sides need calibration if only one bumper corner was hit?+
Yes. The OEM procedure calibrates the pair so the warning zones meet at the correct overlap. Calibrating only one side leaves a coverage seam.
How long does blind-spot calibration take?+
Most jobs run 30 to 90 minutes on-site, including setup, the calibration sequence, and the post-scan documentation. The vehicle stays in your bay the whole time.
Does the calibration come with insurance documentation?+
Yes. Every calibration includes pre-scan, post-scan, the OEM procedure reference, and setup photos, formatted so the carrier approves and pays the line item.
