Good To Know

Q: Do I need to reprogram anything after installing this post? A: The D.E.S.S. post is the physical connection point; lanyard key programming is handled by the ECU, so a replacement post typically does not require key reprogramming.

Q: How can I tell if my D.E.S.S. post needs replacing? A: Common signs include no beep when the lanyard is attached, an engine that will not start, or a loose and corroded contact surface on the post.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
