Abstract
The invention relates to a method for unlocking a locked vehicle door (11) of a motor vehicle (10) by a user by means of an input unit (2) which is arranged on a door handle (1) of the vehicle door (11) and has a haptic signal output, according to which method, in order to generate an identification code having at least one digit, preferably two or more digits, the door handle (1) of the vehicle door (11) is unlocked by means of the input unit (2). According to the method, in the event that a finger of a user touches the input unit (2), in a measure M) for inputting a single number, the input unit (2) generates consecutive haptic signals that can be perceived by the finger of the user at time intervals for output as haptic signals, and according to the method, in the measure M), the input unit (2) generates the haptic signals that can be perceived by the finger of the user. The number of haptic signals that have been generated until the touch of the input unit (2) is stopped is set as a single number of an identification code,-according to which method, measures M) are carried out in total n times in succession in order to input an identification code consisting of n-digit numbers,-according to which the input identification code is compared with a reference identification code stored in the motor vehicle (10), and-according to the method, the number of haptic signals that have been generated until the touch of the input unit (2) is set as a single number of the identification code. When the input identification code is consistent with the stored reference identification code, the vehicle door (11) is unlocked.
