Thanks for the replies. The criminal is my former neighbour, I have tried cabled POE IP CCTV, however, they are using an interference device that temporarily disables live video. Will the police do anything without evidence? If I had the keys deleted and mine added back on, if the criminal tried to unlock the car with the physical key would that set the alarm off? My insurance covers If the car key, or any other device used to unlock your car, is lost or stolen in the UK. If the locks need replacing do I need to contact my insurer before having them replaced? Thanks
