I have this facility on the plant trackers I run. Can stop the machine by sending a KILL code to the machine. I enquired about putting one on my car but the company selling them say they can't do it on vehicles due to the speed and being on a public road.

 

Thanks, that looks like just the ticket and it seems they can be had for quite a lot less than the price tracker quote on their site

 

Cobra Navtrack on my Ferrari. Works very well. I recently moved the car into an adjacent slot in the underground car park without the tracker remote in my pocket. In 30 seconds, they were on the phone asking if all was well.

Burglars will find it near impossible to get to my keys. I live in a relatively secure apartment and the keys are not only well hidden but the remote is in my pocket all the time. Unlike some, I don't sellotape it to the keys!

It reduces my insurance to have this system and it's not that bad at £270 a year.
