S5 rated car tracker systems which are advertised as “Plus” trackers are not part of Thatcham’s certification programme but indicate to customers that these systems will generally have the remote immobilisation feature built in. This means the system has the ability to receive a remotely sent signal to activate the immobiliser. As a result, the engine will not start again until the system has been reset.
