Keystone GM1320255 Parking Assist Sensor OEM Replacement

The Keystone GM1320255 is an OEM-replacement ultrasonic parking assist sensor designed to restore the factory park assist system on compatible GM vehicles. Sourced through Keystone Automotive Industries — a leading distributor of collision and mechanical replacement parts — this sensor is built to match the fit, form, and function of the original equipment component it replaces.

How It Works:

GM's Park Assist system relies on ultrasonic sensors mounted in the front and/or rear bumper fascia to detect nearby objects. The sensors continuously measure the distance between the vehicle and surrounding obstacles, alerting the driver through audible and visual warnings as the gap closes — helping to prevent low-speed collisions during parking maneuvers.

Key Features:

• Direct OEM-replacement design — installs in the factory sensor mounting location without modification
• Ultrasonic detection technology for accurate proximity measurement
• Restores full park assist system functionality when a sensor is damaged, corroded, or faulty
• Built to OEM specifications for reliable, consistent performance
• Plug-and-play connector interfaces with the factory wiring harness
• Distributed by Keystone Automotive Industries, a trusted collision parts supplier

This sensor is a single-unit replacement. Always confirm the correct OEM part number and sensor position (front or rear, inner or outer) for your specific application before ordering.
