You'll want to read this article if you've lost or damaged the o-ring seal that fits under the battery cover on the rear of your InfoKey. We have replacement o-rings in stock. The Segway PT's programable wireless InfoKey was one of several major innovations incorporated into the Segway i2 and x2 range at launch. The InfoKey provided a decoupled User Interface, the ability to change modes, adjust settings, and see operational information (including speed, average speed, trip meter, odometer, time, date, cautions, error codes, adjust the units and programable performance limits, etc). Other innovations first introduced with 'Gen 2' (second generation) Segway PTs included intuitive LeanSteer, clever Roll Compensation when crossing rough terrain, and reduced sensitivity of the LeanSteer input in Turtle mode (making learning to ride a PT for the first time even easier). The InfoKey remains a unique benefit of today's Segway i2SE and x2SE models, which are about to be updated for 2020 with Extended Range battery packs. After a lot of use, or due to damaged caused by dropping, the InfoKey can underperform or stop working altogether. A primary reason for a poorly performing InfoKey is a flat or low-quality button battery (CR2430). You probably won't find a suitable, good-quality button cell for your InfoKey at hardware stores or electronics retailers in New Zealand. Try your local Watch Repairer or Jeweller, and expect to pay three to four times the price per cell compared with cheap, useless cells that won't work properly in the InfoKey. We sell what we believe to be the best CR2430 available in New Zealand. Click on this link to purchase Renata brand CR2430 cells directly from us here at Segway New Zealand. Here's a link to one of our most popular pages: Removing and changing the InfoKey battery. This page includes the following note and warning about the o-ring seal located under the cover on the rear of the InfoKey:

There is one important thing to watch out for when you remove the back, or come to put it back on. There is a thin black rubber O-ring seal that sits in a depression around the circumference of the back face of the InfoKey. When the back cover is screwed down onto this, it makes a water-tight seal. Sometimes, this O-ring can partially lift out, or even completely fall out, when you remove the back cover. If this happens, carefully press it back down into place before you screw the back cover on again. Without the O-ring, not only can water get in, but the back cover will not screw down tightly. This can result in a poor connection between the battery and the InfoKey, causing unreliable operation when you push the InfoKey buttons, and also the regular loss of time and date settings. A poor connection can encourage a user to press the buttons harder than is necessary, eventually resulting in failure of the button mechanism. Failed buttons can be difficult to repair well, meaning the InfoKey has to be replaced.
