## Abstract

A method for controlling access to a vehicle. An electronic key for accessing one or multiple vehicle components is deactivated after the vehicle is switched off in order to park the vehicle in a parking position, so that an attempt with the aid of the deactivated electronic key to access the one or multiple vehicle components of the vehicle parked in the parking position may be prevented. Moreover, a system for controlling access to a vehicle, a parking system for vehicles, an access control system for controlling access to a vehicle, a vehicle, a user for a communication network, a method for operating a user for a communication network, and a computer program, are described.

## Claims

### Claim 1

A parking system for vehicles, comprising:
a parking facility; and
a system for controlling access to a vehicle, including a key management server configured for deactivating an electronic key for accessing one or multiple vehicle components after the vehicle is switched off in order to park the vehicle in a parking position in the parking facility, so that an attempt to access the one or multiple vehicle components of the parked vehicle with the aid of the deactivated electronic key is prevented,
wherein the key management server is configured to provide a new or an additional electronic key to reactivate the deactivated key for accessing the one or multiple vehicle components,
wherein the new or the additional electronic key is generated or created anew by a driver of the vehicle.

### Claim 2 (depends on 1)

The system as recited in claim 1, wherein the key management server receives via a communication network a deactivation instruction for deactivating the electronic key, the key management server deactivating the electronic key in response to the deactivation instruction.

### Claim 3 (depends on 1)

The system as recited in claim 1, wherein the new or the additional electronic key is generated via a mobile terminal.

### Claim 4 (depends on 1)

The system as recited in claim 1, wherein the electronic key deactivates itself after a predefined deactivation time.

### Claim 5 (depends on 1)

The system as recited in claim 1, wherein the switching off of the vehicle is monitored via a vehicle-external monitoring system, an end of the switching off being detected based on the monitoring.
