Keylock with voltage meter suits Zero and other ODM models such as Dragon:
Unicool T and X11 series such as Zero 8/8X/9/10/10X (T10-DDM)/11X and other ODM's such Dragon X9 (keylock models), Dragon Hunter X10 (T10-DDM) & X11, Bexley Black Edition and Apollo Light, City, Pro & Explore.
Unicool VDM-10 including non-NFC Dragon Raptor and models of eGlide MACH 10/10R, Bolzzen Dynamo / Gladiator, Apollo Ghost and Carbon Oxy.
Fitted with 3-pin male JST male connector which is typically plug-and play on above models. Shown on diagrams page. Colours are:
Pin 1 Red = +ve (always on).
Pin 2 Green = Power On (key switch operation).
Pin 3 Black = -ve (this is required for voltage meter display operation.
Connects to the Red, Orange and Black 3-pin female connector on the controller.
Essentially, when the key lock is set to on (to operate scooter), the green wire on the keylock supplies power to pin 1 on the 6-pin connector that runs up stem to display/throttle (which is typically red in colour).
Includes a set of (two) keys.
Sourced as factory spare from the VDM-10 OEM (Original Equipment Manufacturer) spare parts list.
Notes:
Identical to something BSC would supply. The Bolzzen one appears to have more than 3-wires assuming without common +ve.
In most instances, eScooters with QS-S4 throttle/display (often marked 010.1 on rear) can be uplifted to the NFC reader variant as a compatible upgrade, which provides Near Field Communication security (swipe card). This provides an alternative to inserting and turning physical key. The NFC variant uses the same signalling system and wire pinouts on the connector as the non-NFC QS-S4 and offers a facelift upgrade which has an improved enclosure.
Keylocks are a deterrent, but relatively easy to circumvent (bypass) and/or replace. GPS trackers can typically immobilise these models and help with asset recovery.
