Mazda 6 Sports-Line with LogIn remote control Hi, don’t go further, the instructions are thin and not exactly clear … In short: How do I start the car with the spare key or generally with a key without a battery, without the alarm going off? I put my first key (with battery) far away and with the second/physical key the door opens: Alarm goes off. Operating instructions: no indication for proper operation with physical spare key. There is only how, e.g. with the burglary sensor switch off the alarm, namely with the key on the key case – if a battery is in it. Is not. Or how to turn off the alarm when it has gone off: with battery key or with motor, clear. Or “turn off the anti-theft system”, i.e. complete: press the unlock button on the FB. Clear – if a battery is in it. The two-track “theft protection system” is also described: Auto theft or the the theft of objects? Then it sounds “the sirene or the horn or what? What is the connection?
