The key in chime is on all the time, no central locking and radio not knocking off when key removed. I am sure there is a switch activated when the key is pushed in/out ? you cant get to the wiring on the back off the key it seems to be built onto a module and then a multi plug, has anyone changed a lock/ barrel ? is it in need off coding if swapped ?. thanks for any help, regards Jeff.
