My key fob won t open the door?

Generally, there is an indicator light on the key fob, and when we press a certain button, this indicator light will flash. If the indicator does not flash, it means that the key fob is faulty, the battery may be dead, or there is a problem with the remote control itself, at this time you need to change the battery or change the key; If you change a key, still can't open the door, you see if the car's double flashing lights are flashing when pressing the remote control unlock key, if there is no flashing, the car has not received the unlocking signal, if it flashes, it means that the car has received the unlocking signal, and if it still does not unlock, you need to check the car itself.

To check if the door is frozen, we can pull out the mechanical key in the remote control key and directly open the door lock to see if it can be opened. If the door lock is frozen, it cannot be opened with a mechanical key; If the mechanical key can be opened but the remote control key cannot be opened, it means that the fault is still in the electronic control part. If the door lock is frozen, the best thing to do is to use a hair dryer to blow it, usually in a few minutes.

But don't pour hot water, otherwise it will be temporarily opened, and it will still freeze for a while, and even the car door will not be closed.

There could be two reasons, one is a problem with the remote control or radio frequency, and the other is a problem with the main unit or gated part. First of all, check whether the remote control has power, and the battery can be replaced; If it's not a battery problem, try to see if other keys on the remote control can be used, such as opening the trunk; If other keys work, it is a problem with the door control department, and you need to call the maintenance of the remote control**, generally on the packaging or manual**. Hurry up and fix it!

Hello, there should be no electricity, you can remove the mechanical key and open the door, I hope mine can bring you a little help.

There are generally two possibilities:1The battery in the car is running out of power. 2.The key in your hand is dead. At this time, no matter how to deal with or repair it later, we first need to open the car door with a spare mechanical key.

First see if the indicator light on the remote control flashes when the remote control is unlocked, whether it does not flash is the problem of the remote control itself. If the central control of the flashing vehicle does not respond, the central lock unlocking line should be excluded.

Solution: Close the driver's door with the key and see if the other locks are locked.

Disassemble the front main driver's door and check whether the electromagnetic lock inside is in the correct position.

Check the iron lever inside the door for a problem.

1. The car battery is out of power, resulting in the vehicle not receiving the signal;

2. The remote control key is out of power and the door cannot be opened. Don't be in a hurry in this case, each key fob is equipped with a mechanical key that we can use to open the door.

Some models do not have a keyhole on the door handle, what should I do if the remote control key is out of power? In fact, it's not that there is no keyhole, it's just that the manufacturer has designed the keyhole to be hidden in order to make it more beautiful. If you need to use a mechanical key to pick the lock, you must first remove the decorative cover.

The remote control key can not open the door, such a situation occurs, it means that the remote control lock system of the vehicle has failed, and the remote control lock system needs to be rematched, and the specific operation steps of the remote control lock system of the matching vehicle are as follows

1. Open the door on the driver's side of the car.

2. Press the brake pedal of the car to prepare to start the engine.

3. Press the car's one-button start button.

Fourth, the car's instrument lights are all lit up, which proves that the engine is started.

5. Press and hold the lock button of the car driver's door for more than 10 seconds to complete the matching.

The car electronic key cannot be unlocked for the following reasons:

1. First of all, the remote control key has no electricity, replace the battery of the remote control key, and give it a try;

2. It may be signal interference, whether there is a transmission tower near the parking place, and try to stop in another place;

3. It is also possible that the receiving module of the remote control is broken and cannot receive the signal emitted by the remote control.

Hello 1, the car key can't open the door, it may be that the car key is out of power, and the battery needs to be replaced.

The car remote control key is out of power after being used for a long time, resulting in the inability to open the door, which is a situation that car owners often encounter. In this regard, it is recommended that car owners replace the battery regularly and always have a battery in the car in case of emergency. Nanfu's new generation of 4S-level car key special button battery, using polyenergetic dual-core lithium cells, strong power and durability, strong induction, sensitive and long-lasting remote control in actual use scenarios, recommended for the majority of car owners.

If you don't have a battery nearby, or if you still can't open the door after replacing the battery, you can try to open the door using the mechanical key hidden in the key fob.

2. If the mechanical key cannot open the door, it may be a problem such as the central lock of the car or the damage of the lock.

If you can't open the door with a mechanical key, it may be that the central control of the car is electronically locked, or the door lock cylinder is rusty and stuck. When the car's central control system is electronically locked, it is generally possible to try again after waiting for about two hours. When the mechanical lock cannot be opened due to the lock stuck or rusty, it is generally impossible to solve it by itself, and it is necessary to contact the professional staff of the 4S shop for maintenance.

3. The inability of the vehicle to receive the car key signal is also one of the reasons why the car key cannot open the door.

When the vehicle cannot receive the car key signal, it may be that the vehicle itself is out of power, or there is signal interference or shielding around the vehicle. If the vehicle itself is out of power, the car's receiving signal device will not work, and professional rescuers need to be contacted for processing. If there are high-power radio signals of similar frequency around the vehicle or devices that shield the signal, it will also interfere with the received signal, and it can be restored to normal after leaving a certain range.

Finally, remind the majority of car owners and friends that after the above situations are eliminated one by one, if the door is still not opened, then it may be that there is a fault in the car key, door lock or the vehicle itself, etc., and it is recommended to contact a professional car 4S shop for inspection and maintenance.

The reasons why the car key has electricity but cannot be sensed: 1. The car key is faulty. The failure of the car key may be caused by damage to the internal circuitry such as mechanical impact, or it may be caused by the burning of the transmitter components due to water ingress.

2. The battery is dead. The battery is empty, which causes the sensor on the car to not work, and cannot receive the signal from the key, so it will cause induction failure. 3. Electromagnetic interference.

If there is electromagnetic interference in the environment of the car owner, it will cause the signal transmission to be disordered, so that the car key signal cannot be accurately identified. 4. Virtual welding of the distribution box. Poor contact caused by virtual soldering will also cause the inductor to fail.

The most "grounded" way is to gently pat the distribution box with your hand, and it is possible to re-contact the virtual solder joint. However, this is not a long-term solution, and it is still necessary to go to a professional repair shop for repair. 5. The sensor module is faulty.

The failure of the sensor module is equivalent to the direct loss of the "joint" object, and the signal sent by the car key is invalid at this time.

The reason why the car key can't open the door is that the remote control key is dead or the car battery is dead, find a friend's car, take a tie wire to your battery, and unlock the vehicle.

Can't open this door outside the car?

The key battery can be used normally for more than a year, you should not be the key problem, it is possible that the electrical appliances are not turned off after the engine is turned off, and the car battery is out of power,

The key battery can be used normally for more than a year, you should not be the key problem, it is possible that the electrical appliances are not turned off after the engine is turned off, and the car battery is out of power,

If the remote control of the car can open the door, but it can't be opened with the key, in this case, it is possible that the medicine is deformed or the lock hole is faulty, so the key cannot be opened.

Hello! There must still be some problems with this, and the key must still be aware that there may be places that are not in place.

Summary. Hello, there is a solution to the door that can't be opened with the remote control key for the car:1

Check whether the immobilizer has a fault such as a short circuit. 2.Check that the child lock is open.

In order to avoid the situation that the child sitting in the back seat accidentally touches the inner handle of the door when the vehicle is driving, some cars install a child lock on the rear door, when the child lock is locked, the door can only be opened by the handle outside the car, so that if the vehicle is powered off in the state of the door locked, then, neither inside nor outside the car can not open the door, I hope it can help you, remember to help me like it, thank you.

No. It's just that the cab can't be opened.

Hello, if other doors can be opened normally, it means that there is no problem with this remote control key, the problem is that the door lock block in this driver's seat is caused by the failure of the buried rubber lock block, and you need to replace this lock block to be able to open the door normally.

A few times it can still be opened.

Hello, that's right, the door lock block is broken is this reason, my car was last time, and it took 120 to replace the lock block in the end.

Summary. Sometimes it can be turned on sometimes, in this case, it is necessary to check the remote control battery, to see if the power is normal, if there is no problem, you need to check the circuit board in the remote control, to see if the transmission signal is normal, and you also need to check the remote control receiving module in the car. Take a look at whether this can receive the signal of the remote control normally, these aspects need to be specifically checked, which will cause the door to sometimes open and sometimes not open.

The car remote control key sometimes opens the door, and sometimes it can't open the door.

Sometimes it can be sometimes not opened, in this case, it is necessary to check the remote control battery, to see if the amount before the power is normal, if there is no problem, you need to check the circuit board of the rental foot in the remote control, to see if the transmission signal is normal, and you also need to check the remote control receiving module inside the car huixing. Take a look at whether this can receive the signal of the remote control normally, these aspects need to be specifically checked, which will cause the door to sometimes open and sometimes not open.

Hello, the reason why the remote control can't open the door may be that the remote control is insufficient, if the battery is replaced, it will be a problem with the receiver of the vehicle, and the remote control signal cannot be matched, so you have to go to the auto repair shop to let them match.

The failure of the car key to open the door is due to the vehicle into the anti-theft system, each key has a chip inside, when the vehicle key is lost or the key chip is lost, the vehicle will enter the anti-theft state, then the door will be locked, can not open the door. The start is oil-free and fire-free, and it cannot be started, in which case it is necessary to use a decoder to match the key, and then grind out the key teeth for use.

This, I think it's still your battery, if your battery is okay, I think it should be you, or the infrared thing in the bar inside it is broken, right?

The car door won't open, the remote control has power, and now it's what to do if you don't have a mechanical key.

If it really can't be opened, and the battery is also replaced, it may be that the inside is broken, and you should go to the 4S shop to repair it.

There could be two reasons for this:

1.Problems with the remote control or radio frequency.

2.Problems with the host or gating section.

First of all, check whether the remote control has power, and replace the battery; If it's not a battery problem, try to see if other keys on the remote control can be used, such as opening the trunk; If other keys work, it is a problem with the door control department, and you need to call the maintenance of the remote control**, generally on the packaging or manual**. Repair it as soon as possible.

One is that the remote control battery is dead, the second is the fault of the remote control itself, the third is that the receiver does not receive the signal, and the fourth is the problem of the bad five-line motor If it can be locked in the car, this can be ruled out

Can the one that can't be opened be opened before? Generally, it may be a problem with the receiver, if the original car is a 4S shop, if it is an iron general or something, you can find a general equipment to see if they will generally point to the circuit!
