What should I do if the mechanical key can be twisted but the door cannot be opened?

The mechanical key can't open the door:

1. The operation is not right, and the direction of screwing the key is wrong, and in most cases the direction of screwing the key is clockwise.

Unlocked, locked counterclockwise.

2. Most owners will use the remote control key to open the door or lock the door, and less use the mechanical key to unlock the door, and the lock hole will be rusty due to the long-term use.

Tips for using mechanical keys.

You can use this remote control key to find a car in the parking lot, although we all know that there are many large shopping malls nowadays.

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change.

In particular, the passenger car compartment is no longer the same old face. However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

You can use the battery of other vehicles to power up, and you can open the door after the car is powered on.

Preparation materials: a jumper start cable, a rescue vehicle.

Specific steps: 1. When the vehicle loses power and cannot be started, the wiring method is generally used to start the car, and the standing car battery is taken out.

2. Open the hood and battery protective shell of the two cars to expose the positive and negative poles of the battery. Whether it is a rescue vehicle or a rescue vehicle, the operation of the battery should be carried out in the state of flame-off, and the positive and negative poles of the battery must be confirmed.

3. Take a tie wire, connect one end to the positive pole of the unpowered battery, and connect the other end to the positive pole of the electric battery. Do not touch the positive and negative electrodes, there is a danger of short circuit!

4. Take another wire, first connect the negative electrode with the electric battery, and then connect the other end to the negative electrode of the non-electric vehicle.

5. After the wire is set up, you can start the vehicle with power loss and open the door.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! Possible causes and solutions for mechanical keys that twist but can't open the door:

First, the connecting rod between the left front door lock cylinder and the lock body has fallen off, in which case you need to remove the door trim panel and check whether the connection has fallen off. If it falls off, it needs to be reconnected. Second, the left front door lock body is faulty.

If the lock body is faulty, it is not necessarily that we open the door, but he only affects the mechanical key, and it cannot be opened when the door is opened. When the car is electrified, it can be unlocked by remote control. Then drive to the repair shop to have it checked.

The car has electricity. The mechanical key can be twisted left and right, but the door can't be opened.

Possible reasons and related solutions for the mechanical key to twist but not open the door: First, the connecting rod between the lock cylinder and the lock body of the left front door has fallen off, which requires removing the door trim panel to check whether the connection has fallen off.

If it falls off, it needs to be reconnected. Second, the left front door lock body is faulty. If the lock body is faulty, it is not necessarily that we open the door, but he only affects the mechanical key, and it cannot be opened when the door is opened.

When the car is electrified, it can be unlocked by remote control. Then drive to the repair shop to have it checked.

This should be the connection position between the lock cylinder and the lock body falling off.

Can you fix it yourself?

It's more troublesome to tidy up by yourself. First of all, you need to know how to disassemble and assemble. If you have strong hands-on ability to disassemble and assemble, you can tidy it up yourself. Remove the interior panel of the front left door first. Observe the position of the lock cylinder, look at the connecting rod, and re-fasten it if you drag it.

Are there any other reasons.

No, there are two failures. Either the connecting rod I'm talking about is falling off, or there's something wrong with the lock body.

That reason is more likely.

If you can twist left and right, there is a high chance that the connecting rod will fall off.

3. In most cases, there will be no big problem with the mechanical key, if there is a problem, it may be the key that is reconfigured later, and the key needs to be replaced if it is incomplete.

Question: I used a mechanical key to pick the lock.

But today it can't be opened, and there is no response.

If the door cannot be opened with a mechanical key, it means that the door lock of the vehicle is broken or the internal mechanism is damaged.

If you open the door with a mechanical key, you will find that the key seems to have no resistance. Generally, the key decoupling is decided, which will affect the invalidity of the mechanical key. Some models will enter the anti-theft lock state when the car is locked, not only the engine will be locked, but also the vehicle's central control system will be locked.

At this point, the mechanical key will be prohibited from opening the door.

The mechanical key cannot be completely removed, and the mechanical tooth part can be ejected by the folding button on the key.

The mechanical teeth can be completely removed by means of a folding button on the key.

In most cases, the door lock mechanism of the vehicle** lock locks the door with a mechanical latch. If the door is not locked, it can only be opened with the outside doorknob. If there is a lock key in the car, you need to enter the car and start the ignition.

At this point, the vehicle will be unlocked. In this case, only the glass of the vehicle can be broken to enter the car, and the damage caused by this method is very large.

During the use of the vehicle, the vehicle needs to be maintained regularly to prevent some failures from affecting the normal use of the vehicle.

If several keys cannot be opened, it is necessary to check the keyhole in the door for foreign objects or abnormalities.

If you make sure that there are no foreign objects in the key of the vehicle, the vehicle, or the keyhole. It is recommended to drive the vehicle to the maintenance facility for further inspection to confirm the cause of the failure.

1.The reason why the mechanical key won't open the door could be that the car's central locking system is electronically locked and takes an hour or two to try to unlock it. In addition, it may also be a mistake to lose the spike, lock cylinder and mechanical key.

2.There are mechanical keys, remote control keys, family touch LCD keys, and smart bracelet keys.

3.A car key is a tool that opens and closes a car. Now all car keys use chips, which are magnetic chip systems.

4.The reading coil of the car's dust detection ignition lock cylinder will read the chip's key, which has fixed digital information.

The first possibility of the mechanical key opening the door is that the central lock system of the car is in an electronic locking state, and it is necessary to wait for an hour or two after the lock is cleared before making an unlocking attempt. Due to the long-term use of the lock hole, there will be rust in the lock cylinder, you can try to add some engine oil to the lock cylinder, lubricate it, if it still can't be opened, you need to replace the lock cylinder.

1. The operation is not right, for example, the direction of the key is wrong, in most cases, the direction of the key is unlocked clockwise, and the lock is counterclockwise.

2. Most of the owners will use the remote control key to open the door or lock the door, less use the mechanical key to unlock the door, the lock hole will not be used for a long time, the lock cylinder will be rusty, you can try to add some engine oil to the lock cylinder, lubricate it, and see if it can be opened, if it still can't be opened, the lock cylinder needs to be replaced.

3. There is a problem with the mechanical key In most cases, the mechanical key will not have any big problem, if there is a problem, it may be that the key is reconfigured later, which is incomplete.

In the early morning of winter, sometimes the mechanical key does not screw the door to open the car, which is caused by the residual water entering the keyhole after the car wash, when the key is inserted into the keyhole, the locking mechanism inside can not be bounced, and the key can not be twisted. At this time, do not twist it vigorously, otherwise it will cause damage or deformation of the key and become unusable.

When you turn the key, you find that the key doesn't seem to have any resistance, which basically means that the mechanical key is not working due to the "decoupling". In some cars, if the anti-theft lock state is in the anti-theft locking state, not only will the engine lock, but the central locking system will also prevent the mechanical key from opening the door. Under normal circumstances, the door lock mechanism of the central lock of the car is to lock the door through the mechanical lock.

If the door lock is not locked, the door can be opened by the outside door handle and the door handle.
