Claims

[Scope of utility model registration request]

In a keyless entry device that inputs a code signal using Morse code using an outer handle switch that operates in conjunction with the operation of the outer door handle as a means of inputting a code signal from outside the vehicle, when writing a code. , detects the completion of the write operation and issues a confirmation reminder signal, and when the operator inputs the code signal again for confirmation, compares the input with the previously written and memorized code, and if they match, OK. an arithmetic circuit that emits an NG signal if the signal is different, and a sound generator such as a buzzer that emits a confirmation reminder sound signal, an OK tone signal, and an NG sound signal based on the above-mentioned signals of the arithmetic circuit. A keyless entry device for an automobile, characterized in that:
