Good To Know

Q: Will my existing lanyard key work with this post? A: The D.E.S.S. system matches keys to the post, so a new post may need to be programmed to your key or vice versa depending on your model.

Q: How do I know if my D.E.S.S. Post is failing? A: Common signs include a no-start condition, an error beep sequence, or the engine shutting off when the lanyard is attached.

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