The Audi A3 often fails to pull out the key after the ignition is turned off

Some cars have a flame-out protection interlocking device, when the car gear is not hung on P or N, the key cannot be pulled out; In addition, the failure of the key cylinder rotary clip of the flame-out key will also cause the key to not be pulled out; Go to the repair shop and disassemble the electric door key to check and reinstall it.

1. First of all, the car should be turned off and should pay attention to the delay of the ignition, which is good for the engine, just like people need to walk slowly after running fast to fully recover, so after reaching the goal, when the ignition is turned off, you should pay attention not to turn off the key immediately, you can sort out the items in the car, close the window, and the delay time is best about 30 seconds.

2. The engine with vortex supercharger needs to be turned off for a delayed time, so that the engine and turbine have enough time to cool and lubricate before turning off after stopping, which can protect the engine and help the engine and water temperature to cool; In colder weather, you can start the car first and let him warm it up.

When the key is pressed, the inside and outside door handles of the car are locked at the same time. Press twice to lock the outside of the car without locking the inside, and press the lock button in the car to have one effect. The rear child lock only locks the inner handle, not the outside handle.

The driving automatically locks only the outside of the car, not the inside of the car. After the driving is automatically locked, the key is pulled out when the engine is turned off, and the four doors are unlocked at the same time. After the driving is automatically locked, open the driver's door, and the four doors are unlocked at the same time (it can also be set to unlock only the driver's door), after the driving is automatically locked, which door is opened from the car, and the door handle is unlocked.

Summary. Hello. Friend.

Reasons: 1. The central locking system of the car is in an electronic locking state; 2. The operation is not right, and the direction of the key is wrong; 3. The lock cylinder is rusty.

Solution: 1. Wait for one or two hours for the lock to be lifted, and then try to unlock it; 2. Unlock clockwise; 3. Add engine oil to the lock cylinder for lubrication.

Hope it helps.

Neither the Audi A3 key nor the mechanical key can be opened.

Hello. Friend's reason: 1. The central lock system of the car is in an electronic locking state; 2. The operation is not in the right direction or the draft is wrong; 3. The lock cylinder has a rusty phenomenon, which group shouts.

Solution: 1. Wait for one or two hours for the lock to be lifted, and then try to unlock it; 2. Unlock Li Ye clockwise; 3. Add engine oil to the lock cylinder for lubrication. Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

I'll take a look at the fault code, friend.

Thank you. The door can't be opened, how to see the error code.

Good. Wait a minute, it takes time for a friend to type by hand, wait a minute, thank you, friend.

Solution: The first possibility is that the car central lock system is in an electronic lock state, and you need to wait for one or two hours for the lock to be lifted before making an unlocking attempt. The second possibility is that after a long time, the door lock cylinder is stuck, and it can't be turned with light, so if you want to solve it yourself, you can only take a violent way, that is, smash the glass to open the door.

Otherwise, you can contact the 4S shop for repair.

There are three situations when the key fobs fail: first, the transmitter of the key is broken, and the firing command is incorrect. Second, the car's receiver was broken and the doors could not be controlled. The third crack rent, the battery in the key is dead.

The working principle of the remote control key is simple: first send a weak radio wave from the key, receive the erection radio wave signal by the car antenna, identify the signal ** by the electronic control unit (ECU, e le CT ronic control unit), and then carry out the action of opening and closing by the actuator (motor or electromagnetic coil) of the system.

The system is mainly composed of two parts: the transmitter and the receiver knowledge source machine.

Transmitter: It is composed of a transmitter switch, a transmitter antenna (key board), an integrated circuit, etc. It contains a memory loop and an amplitude modulation modulation loop, and a button-type lithium battery is installed on the opposite side of the circuit.

The transmitting frequency is selected according to the radio standard of the country of use, and the transmitter switch transmits the signal once every time the button is pressed.

Receiver: After the transmitter uses short-wave modulation to send out identification**, it is received through the short-wave antenna of the car, and the short-wave high-frequency amplification processor that enters the electronic control unit of the receiver is used to demodulate and compare with the identification ** of the demodulator; If it is correct**, enter the control circuit and make the actuator work.

Summary. Dear, glad to answer for you! Audi A3 keyless entry does not respond to the following reasons:

1. The battery is dead. In order to ensure the normal use of the vehicle, the battery manager will temporarily shut down the system, and the keyless entry system will not respond. 2.

If the key is low on battery or there is a problem with the key itself, it can be judged by replacing the key battery or key; 3.Signal interference, because when the system is working, the position of the key is transmitted via wireless status. When the signal is interfered with or shielded from the outside, the system becomes dysfunctional.

4.The doorknob, touch sensor, and signal receiving antenna are damaged, or the circuit is broken due to virtual connection.

How to reactivate keyless entry.

Dear, very and disturbing the dust is happy to answer for you! Audi A3 keyless entry does not respond to the original call Zen because: 1. The battery is dead.

In order to ensure the normal use of the vehicle, the battery manager will temporarily shut down the system, and the keyless entry system will not respond. 2.If the key is low on battery or there is a problem with the key itself, it can be judged by replacing the key battery or key; 3.

Signal interference, because when the system is working, the position of the key is transmitted via wireless status. When the signal is interfered with or shielded from the outside, the system becomes dysfunctional. 4.

The doorknob, touch sensor, and signal receiving antenna are damaged, or the circuit is broken due to virtual connection.

There may be the above problems, which will lead to no response.

You can try changing the battery first.

Summary. Hello dear oh, I'm glad to answer this question for you, and I have found the answer to this question for you: Audi A3 remote ignition with the key did not respond to the reason:

Whether the Audi A3 steering wheel is deadlocked: When parking, if the steering wheel is misaligned, the angle is slightly larger For example, if it is more than 30 degrees, the steering wheel will automatically lock, which is also an anti-theft measure. At this time, the key may not be opened remotely, resulting in ignition failure and whether the Audi A3 has been changed back to P gear when parking, and it will have an impact if it is not.

Hello dear Hello, I'm glad to answer this question for you, and I've found the answer to this question for you: Audi A3 remote ignition with a key does not respond to the reason: Audi A3 whether the steering wheel is deadlocked:

When parking, if the steering wheel is misaligned, the angle is slightly larger For example, if it is more than 30 degrees, the steering wheel will automatically lock, which is also an anti-theft measure. At this time, the key may not be opened remotely, and the ignition failure caused by the wild shed has not been watched when the parking has changed the Audi A3 back to P gear, and it will have an impact if there is no success.

Hello dear: one-button start can sometimes lead to trouble with the Audi A3 smart key running out of power: obviously, the key is in the car, but the instrument always shows the wrong key match.

This situation is most likely due to the fact that the smart key is running low on battery and the boot system is unable to sense the weak radio waves emitted by the key. So it is recommended to put the smart key on the start button and press the button to start. Check if the Audi A3 battery is charged:

The failure to ignite may be due to the loss of power caused by the headlights being left on for a long time or the expiration of the battery life. Under normal circumstances, the battery should be replaced in time according to the maintenance manual of Yuanhong. In addition, xenon headlights, high-power audio, etc. are installed.

It is also the cause of vehicle circuit failure. It is easy to check if the vehicle is hail bent or not. Just honk your horn.

The Audi A3 is equipped with one-button start from the 2020 model year. How to use the one-button start of Audi A3: first press the start button, after the ACC light is on, then press the start button, then the one-key start button is in a green state and the vehicle is self-checked.

When the vehicle completes the self-test, the brakes are pressed, the one-button start button is pressed again, and then the Audi A3 vehicle starts.

The version of the Audi A3 before the 2020 model year uses a key to start the ignition, and some models of the 2020 model year are equipped with a one-button start function, and the model with a one-button start does not need to insert the key, and only needs to press the one-button start button to start the vehicle.

How to use the one-button start of Audi A3, first press the start button, after the ACC light is on, and then press the start button, then the one-button start button will be green, and the vehicle will conduct a self-check. When the vehicle completes the self-test, the brakes are pressed, the one-button start button is pressed again, and then the Audi A3 vehicle starts.

The one-button start device is a part of the smart car, is a button device to achieve a simple start process, and can also be turned off, the device can be modified at the position of the original car key lock, or can be modified with an independent panel, and its start mode is a software one-button start. Different from the mechanical key ignition method and the traditional start procedure of the bridge system, as long as you gently press the key to start the start button button, you can start and turn off the ignition, avoiding the trouble of losing the key and finding the key, and most of the time you need to step on the foot brake in the process of ignition.
