A lawn care device may include an engine to selectively power the device, a frame supporting the engine and an operator of the device, and an ignition interface having processing circuitry configured to define a plurality of operating modes. The operating modes may include at least a starting mode in which the ignition interface is usable by the operator to start the engine, and a running mode in which the engine is running. The ignition interface may include code entry keys configured to, responsive to entry of a code via the code entry keys, enable use of the ignition interface to shift from the starting mode to the running mode without a physical starting key.
