Before going paranoid over key code grabbers have a look at what Snopes has to say...……….
FACT CHECK: Code Grabbers and Remote Keyless Entry?
However, times change and technology advances. In response to the fixed code security weakness, automakers
shifted from RKEs with fixed codes to systems employing rolling random codes. These codes change every time a given RKE system is used to lock or unlock car doors and thus
rendered the earlier ‘code grabbers’ ineffective. That form of more robust code system became the industry standard for remote keyless entry systems in the mid-1990s, so automobiles newer than that are not vulnerable to being quickly and easily opened by criminals armed with the first generation of code grabbers.
Another thing not to worry about.
