Trunk Lock Button Tesla Model 3 Y 2017-2023

Tesla Model 3 and Model Y Trunk Lock Button — the New Safety Switch

This trunk lock button for the Tesla Model 3 and Model Y replaces the frunk or tailgate safety switch, which allows the trunk to open and signals that it is closed to the computer. When the trunk refuses to open, remains displayed as open, or triggers a phantom alert, this small part is to blame nine times out of ten.

A Design Tailored for Your Tesla Model 3 and Model Y

The switch exactly matches the footprint, travel, and connector of the original part, under part numbers 1516185-00-A and 1107722-00-D. It fits into its housing without any play or shims, uses the same sealing gasket, and restores the front or rear trunk to a factory-standard operation.

Technology, Quality & Finish

Moisture-sealed housing, high-endurance contact membrane, and pin configuration compliant with the manufacturer's standard: this is precisely the lack of sealing that causes worn switches to fail. Located on the edge of the opening, this safety switch withstands splashes, dust, and condensation without losing its contact reliability.

Installation, Compatibility & Durability

Installation is a direct replacement: remove the trim, disconnect the connector, swap the part, and reassemble. No coding or diagnostic tool is required. Compatible with Tesla Model 3 and Model Y vehicles produced from 2017 to 2023; compare the part number 1516185-00-A or 1107722-00-D engraved on your original part before ordering, as the fit varies depending on the opening.
