Electronic anti-theft lock

Electronic anti-theft lock prevents unauthorized use of the vehicle.



A microcircuit is built into the key handle, with the help of which the anti-theft lock is automatically disabled when the key is inserted into the ignition switch. When the key is removed from the ignition switch after the car is stopped, the anti-theft lock automatically enters guard mode.

Warning: Your vehicle's engine can only be started with a properly coded original Audi key, see. Controls and instruments.

Under certain circumstances, the engine may not start if another vehicle's ignition key is on the keychain.

Single control lock system

The single-control locking system allows all doors, the trunk and the fuel filler flap to be locked or unlocked simultaneously.

When the vehicle is unlocked and locked with the single control locking system, all doors and the fuel filler flap are simultaneously unlocked or locked. The trunk lid is unlocked and then opened using the handle. The vehicle can be unlocked and locked using the radio remote control or the key on the driver's side door.

You can also open and close windows at the same time.

The sliding and lifting roof panel* can only be closed using a single lock.

The single control lock system is equipped with protection against hacking. When the car is locked from the outside, the door release handles inside the car do not work. This makes it more difficult to break into the car.

If the single control locking system fails, all locks can be opened and closed separately with the key. The exception is the fuel filler flap. Emergency release of the fuel filler flap, see. Refueling a car.

Automatic locking*

When the vehicle speed exceeds 15 km/h, all doors and the trunk are automatically locked.

The vehicle will automatically unlock again once the ignition key is removed from the lock. The vehicle can also be unlocked by pressing the button located in the driver's door or by pulling the door handle twice.

Locks with a single control provide the possibility of an automatic locking function.

Warning: Locks with a single control can be equipped with an additional level of security function if desired.

If the single control locking system is faulty, the driver's door and boot can be unlocked and locked with the key in the normal mode. Emergency release of the fuel filler flap, see. Refueling a car. Emergency door locking, see below.

If the single-control lock system fails, it is impossible to activate the burglar protection and security alarm*.

Remote control of locks

The radio control lock system allows you to unlock and lock your car remotely.

Functions of the radio remote control system:

• Unlocking and locking the car
• Unlocking the trunk

Unlocking and locking of the vehicle is confirmed by flashing of all direction indicator lights. In addition, when the switches are in the door contact position, the interior lighting is automatically switched on or off.

The transmitter with the power supply is built into the handle of the radio key. The receiver is located in the car. The maximum range is determined by various factors. As the power supply discharges, the range decreases.

An integral component of the radio key is a folding key bit, designed for mechanical unlocking and locking of the car, as well as starting the engine.

When replacing a lost key, as well as after repair/replacement of the receiver, the remote radio control requires initialization. Only then can it be used.

Warning: When the ignition is turned on, the radio remote control device is automatically turned off.

A temporary negative impact on the performance of the device may be caused by the overlap of transmitters operating in the same operating frequency band and located near the vehicle (for example, mobile phones, television stations).

Unlocking and locking the car

To turn off the security alarm, within 15 seconds of opening the car from the driver's door, insert the key into the ignition switch and turn on the ignition. If you do not turn on the ignition within 15 seconds, then the alarm will sound.

When does the security alarm go off?

When the vehicle is locked, the system monitors the following potential attack targets:

• underhood space (hood)
• trunk
• doors
• horizontal position of the car
• ignition
• radio system (only original Audi radio system)
• car interior.

The security alarm is triggered when any of the named objects is entered.

When the trunk is unlocked and opened with the key, the security alarm is also triggered.

How do you turn off the security alarm?

The alarm system is switched off when the car is unlocked by the remote control or the ignition is turned on with the key. The alarm system is also switched off at the end of its operating cycle.
