## Abstract

The invention relates to an access key (1) for unlocking a motor vehicle, comprising:—a communication interface configured so as to communicate according to an NFC protocol;—a support containing data constituting service provision rights,:—a monitoring circuit (111) able to process a transaction by way of said communication interface (112) on the basis of said data constituting the service provision rights; characterized in that it comprises a housing (106) for receiving a support containing data constituting service provision rights of removable type (2), and in that it comprises a read and/or write interface (113) in the removable support placed in the housing, the monitoring circuit (111) being configured so as to allow an exchange of data between the communication interface and the read/write interface.

## Claims

### Claim 1

An unlocking key for accessing a motor vehicle, comprising:
a communication interface configured to communicate according to an NFC protocol;
a medium comprising data constituting service provision rights;
a control circuit for processing a transaction via said communication interface on the basis of said service provision rights;
a housing to receive the medium comprising data constituting service provision rights, wherein the medium is removable; and
a read and/or write interface in the removable medium placed in the housing, the control circuit being configured to allow an exchange of data between the communication interface and the read/write interface.

### Claim 2 (depends on 1)

The unlocking key as claimed in claim 1, further comprising a casing housing the control circuit, wherein said housing is disposed in the casing.

### Claim 3 (depends on 2)

The unlocking key as claimed in claim 2, wherein a sealed enclosure is disposed inside the casing, said sealed enclosure containing the control circuit.

### Claim 4 (depends on 3)

The unlocking key as claimed in claim 3, wherein the housing is separated from an enclosure part containing the control circuit, the casing comprising a removable case configured to selectively provide access to said housing or to isolate said housing from the outside.

### Claim 5 (depends on 1)

The unlocking key as claimed in claim 1, wherein a receptacle configured to receive a battery is disposed in said housing, the key comprising two electrical contact studs configured to come 1282352 2 into contact with two poles of a battery disposed in the receptacle, said studs being electrically connected to said control circuit.

### Claim 6 (depends on 1)

The unlocking key as claimed in claim 1, wherein the housing is disposed in a drawer mounted in a sliding manner in relation to the casing, so as to be able to selectively place the housing outside the casing.

### Claim 7 (depends on 1)

The unlocking key as claimed in claim 1, wherein the read/write interface has contact studs projecting into the housing, this interface having an electrical connection connecting the contact studs to the control circuit.

### Claim 8 (depends on 1)

The unlocking key as claimed in claim 1, wherein said housing comprises at least one guide rail configured to guide a removable medium in a sliding manner inside the housing.

### Claim 9 (depends on 1)

The unlocking key as claimed in claim 1, wherein the removable medium is a microprocessor card.

### Claim 10 (depends on 9)

The unlocking key as claimed in claim 9, wherein the removable medium is a microprocessor card in SIM card format.

### Claim 11 (depends on 1)

The unlocking key as claimed in claim 1, wherein the housing of the removable medium comprises a slot to receive a payment card in calling card format.
