What if the key will not start my segway ?
There are a number of issues that should be investigated. First, ensure that your key and the key port on the machine are both clean and dry. Water or moisture in the key port may interfere with proper communications to the key. If required, wipe the key port with an absorbent material. Second, check the charge on your batteries and if neccessary charge your batteries for one hour and then start your Segway HT. If the device starts, continue recharging the batteries for another 5 hours.
