No matter how the children s remote control car was made, there was no response

Let's try to see if it's a remote control first.

It's broken, you find a phone that can take pictures, turn on the camera, and then press the remote control against the camera of the phone, if you can see some blue light from the screen of the phone, it proves that the remote control is good, and you can find the reason from the aspect of the car.

If there is a problem in the car, it is recommended not to disassemble it yourself, but to repair it at the place where you bought the toy car.

Extended Information: A RC car is a model car that can be controlled remotely by radio control. Generally, it can be divided into:

Toys, model cars (R C), police and other categories. According to the appearance of the car body, it can be divided into: RV (flat car), off-road vehicle, monster truck, rally car, container truck, etc.

RC model cars are abbreviated as RC

car, RC model cars are not toys, they are"A scaled-down version of a real car", which has the same powertrain (engine, gearbox) as a car, as well as the suspension.

There are high-performance tires that can withstand a centrifugal force of 4 g equivalent to that of F1.

It also has those supercars in the real car.

Not a bad situation:

1. The toy car does not have a battery or is out of power.

2. The remote control is not equipped with a battery or is out of power.

3. The remote control distance is too far.

4. There is an obstacle between the remote control and the toy car.

Broken case:

1. The remote control induction probe is broken.

2. The receiver of the toy car is broken.

3. Toy car line problems.

4. Problems with the circuit board of the remote control.

5. Miscellaneous.

Summary. 1. The remote control is out of power. When there is a situation where the remote control cannot be remotely controlled, parents first check whether the remote control has power. If it is due to the battery, you can replace it with a new battery and use the remote control again.

Hello, there may be a situation where the remote control cannot be remotely controlled, then it may be caused by the following factors:

1. The remote control is out of power. When the remote control cannot be remotely controlled, parents first disturb the state to check whether the remote control has electricity. If it's because of the battery, you can replace it with a new one and you can use the remote control again.

2. Check the electric motor of the stroller. In addition to checking the remote control to celebrate the change, parents also need to check the motor under the stroller. If there is a problem with the motor, you need to seek professional help.

3. Check whether the carbon lance is worn. If the carbon lance that controls the motor of the stroller is worn, the remote control will not be used.

If it is not a problem with the battery, it may be because the remote control has been used for a long time, and a lot of dust and dirt have accumulated on the circuit board, resulting in poor contact.

If you find that the key fob is not responding when unlocking or locking the vehicle, and you notice that the small light on the key is not flashing, it is possible that the battery in the key is depleted and needs to be replaced. Even if the key fob has no power supply, the mechanical key hidden in the key fob can unlock or lock the vehicle. If you have time, it only takes 10 minutes to go to the 4S store to replace the key fob.

<> due to strong radio interference, the vehicle could not successfully receive the key fob signal. Now, move the vehicle to a distance and try the key function. RC cars usually refer to remote-controlled models, usually including car toys, car models, police cars, etc., which can be divided into the following according to the body shape

Campervans, SUVs, monster trucks, rally cars, model remote control is not a toy, but a "simplified version of a real car" with its powertrain.

Same with cars.

The low power of the key fob battery will cause the key light to flash, but the door will not close. Low power and low voltage can lead to unstable circuit performance and shorten wireless communication.

Distance. At this point, the vehicle can be locked near the body. If necessary, simply replace the battery.

The RF forms of the remote key include short-range remote sensing and short-range wireless RF, no matter which form of the two, its transmitting circuit and receiving circuit are prone to failure, which is determined by three factors: the design of the circuit, the level of components, and the conditions of use.

The key fob of the car takes radio waves.

In the form of sending the letter Chunling, the radio waves will be received by a receiver in the car. High-voltage towers, base stations, and other devices, including thunder and fog on rainy days, can crack and interfere with radio waves, which have a certain penetrating ability to penetrate the base, so we can operate remotely even through walls or buildings, but the power of radio waves is also affected when the battery is de-energized. Normal face-to-face use will not be a problem, but radio waves cannot penetrate the building.

If the remote control of the remote control car does not respond, first of all, it should be judged whether the chain is broken due to the battery being dead, and if it is to replace the battery. If there is electricity but there is no response, it may be that the car is dusty or the remote control is faulty and needs to be repaired. Brother Potato.

After seeing if the car motherboard has dropped the wire, you will know the specific situation.

Summary. Dear, hello, the reason why the remote control of the toy remote control car does not respond: after you replace the new battery, first rule out the problem of the battery is out of power, and then check the electric motor of the remote control car, if there is a problem with the motor, you need to find the purchase manufacturer to consult for replacement or repair, check whether the carbon lance is worn, and the carbon lance that controls the motor of the children's car is worn out, which will also lead to the situation that the remote control cannot be used.

Good. Dear, hello, the reason why the remote control of the toy remote control car is not anti-track: after you replace the new battery, first rule out the problem of the battery is not charged, and then check the electric motor of the remote control car, if there is a problem with the motor, you need to find the purchase manufacturer to consult for replacement or maintenance, check whether the carbon lance is good to wear, and the carbon lance that controls the motor of the children's car is worn out will also cause the remote control to not be used.

Then may I ask which motor and the carbon lance are in that position.

What color is it.

Dear, hello, the carbon lance is the interface after the small dot is loaded into the battery slot, which is mainly used as the positive electrode of the battery. I hope my stool can help you, I wish you good health and a happy mood, thank you for your consultation, and I hope you will take the time to give you a thumbs up and encouragement.

Dear, hello, if you replace the new battery, first check whether the remote control is on when you control the remote control with your control rhythm, if not, you need to consider the reason for the damage to the remote control line, if the remote control is on, but the toy car does not have any response, you need to consider the cause of the damage to the battery interface If you hear the sound of the horse rotten inside the toy car, but the car does not move, you need to consider the motor problem, I hope I can help you, I wish you good health, hunger, early sales, good mood, Thank you for your inquiry, and I hope you will take the time to give us a thumbs up and encouragement.

<> "What's going on with the car remote control not responding."

When you press the button on the car's remote control, only to find that the vehicle is not responding, it is most likely due to a malfunction of the remote fob. The reasons for the failure of the remote control key are generally as follows:

One is that the key fob is too low to send an execution signal. If the key is out of battery, we need to replace it with a new coin cell battery. You can use a small flathead screwdriver to open the mechanical car key, remove the old battery, replace it with a new battery of the same model, and install the car key.

The other is that the signal emitted by the remote key cannot be received normally by the vehicle, which may be caused by the presence of strong magnetic field interference. If the signal emitted by the remote control key does not match the vehicle due to environmental interference, we need to use the mechanical key to start the vehicle, drive away from the current environment and try to use the key fob again. Under normal circumstances, after leaving the strong magnetic environment, the remote control key can resume normal use.

There is also the fault of the key itself. If the key itself is faulty, such as accidentally soaking in water or falling from a high place, the circuit board in the key may have been broken or short-circuited, at this time we need to use a spare key or go to the 4S store as soon as possible to get a new key.

In addition, if there is a fault in the vehicle itself, then it will also cause the car remote control to be unable to respond, and the owner can deal with it differently according to different situations.

If it is determined that it is the key of this car, and it cannot be opened by pressing the unlock key, there are two possibilities, one is that the control unit of the key is broken, and the other may be that the key code does not match, and you have to match it with the computer again. See if there is a problem with the car's immobilizer, if not, see if the key is broken or whether there is a problem with the car's central control.

Or there are several ways to do this:

One: Spare key solved.

Two: change the battery for the key.

Three: If the spare key is not around, you can find a family member to take the spare key to the mobile phone that is talking to you and press the unlock key, and you are holding ** in front of the car, it is possible to open it.

The biggest advantage of the remote control key is that it can be unlocked and locked from a distance and conveniently without the need to find the lock hole, regardless of day or night. Weak radio waves are emitted from the side of the car owner, and the radio wave signal is received by the car antenna, and the signal is identified by the electronic controller ECU, and then the action of opening and locking is carried out by the actuator of the system. Now the car key is using a chip, a magnetic chip system, once the remote control key circuit board fails, it is the same as the loss of the key, then press the car key press does not respond, can only replace the new key.

Building blocking will also affect the function of the car key, radio waves have a certain ability to penetrate, so that even through a wall or a building can be operated remotely, but as the battery power drops, the strength of the radio waves will also be affected. It may be possible to use it face-to-face normally, but when it is separated from the building, the radio waves cannot penetrate it.

The most common reason why the remote control of the car does not respond when pressed is that the battery of the key is dead, and the battery can be replaced.

In addition to the lack of power on the key itself, there may be other electronic signal interference, the key's circuit chip failure, or the receiver in the car failure, in this case, it is recommended to go to the auto repair shop for maintenance.

1. It is possible that the key is out of order, or the "key" on the remote control is pressed, dented, collapsed, and the contact is poor. (physical failure, replacement);

2. The battery of the remote control fails, and it may fail due to the fact that it may be used for too long in time or the discharge of the battery itself, resulting in the failure to reach the normal transmission power. (Replace the battery);

3. The signal receiving module is faulty, or the receiving module is interfered with or blocked by the surrounding components, making the signal difficult to receive or weak or unable to receive the signal (frequency) transmitted by the remote control, resulting in failure. (check or adjust the position);

4. In addition to the fault caused by the line, the host may be short-circuited, broken or burned internally, which is subject to the electrician's test results.

Question: Hello teacher, the computer has detected that the connection between the immobilizer and the ECU has failed.

The central control anti-theft device does not respond when pressed by hand.

The one-button start does not work, the power does not work, and the instrument cannot be opened.

The answer should be that the anti-theft work, to solve the anti-theft line, try to switch the key a few times to see if it works, if it doesn't work, you can only use diagnostic instruments to match and learn the anti-theft computer, of course, it is possible that the anti-theft computer is broken, then it is more troublesome. Then you have to change the computer. Changing the anti-theft computer requires code matching, etc., which is more troublesome.

The car's remote control is not responsive, generally speaking, the car's remote control key is not electric, or there is interference nearby.

One is that the battery is dead and the keys are out of order.
