The signal jamming device 30 has a transmitter 32 which transmits a jamming signal JS to jam a remote keyless authorisation signal KS. The jamming device preferably has a receiver to detect a keyless authorisation signal so the jamming signal can be transmitted in response, where the jamming signal preferably has a number of jamming signal frequencies. The jamming device preferably has a control to deactivate the jamming signal, which may be a button 34 or a switch. When the control is a switch the transmitter can be placed in persistent jamming mode or switched off. The jamming device may be used with a smart key 20 or may be integrated with a smart key.
