What is the reason why the remote control key and the mechanical key can t open the door?

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.

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 reason why the car key does not open the door is that the remote control key is dead or the car battery is dead, or there is strong signal interference around. You can use the mechanical key hidden inside the remote key to open the door, if the mechanical key can't open the door, the door lock is faulty.

If the car battery is out of power, the car's induction system will naturally fail, resulting in failure, and the car needs to be charged.

The key battery is out of charge and lost.

The most likely thing to happen is that the car key battery is out of power and causes failure, the battery life of the general car induction key is about 2 years, if it is out of power, it is impossible to open the car door inductively, the car key battery that uses a key to start is out of power, and the door can only be opened with the spare key in the induction key.

In the encounter with strong magnetic field and other interference information around, it will affect the induction key, can only try to unlock in different directions around the car, you can press the unlock button at the same time, while playing ** The success rate will be higher. If the mechanical key cannot be opened, it may be that the car lock system is electronically locked, or the door lock cylinder is stuck.

The remote key fobs don't work, why doesn't the mechanical key work either?

One situation is that when you turn the key, you find that the key does not seem to have any resistance, which is basically a conclusion of "decoupling"! The resulting mechanical key does not work.

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.

By what you mean, there's no way to open the car door anyway. In this case, it is not, and you will know if you continue to look back.

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.

The mechanical key can't open the door: 1. The operation is not right, and the direction of the key is wrong, in most cases, the direction of the key is to unlock clockwise and lock it 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. 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.

Jammers and criminals lurk around: Many criminals often use a jammer device to send out electromagnetic waves in the same frequency band to actively interfere with the signal sent by the remote key, and there is no response when the key is pressed at this time. If the owner of the car does not pay attention to the lock signal after pressing the lock button, or does not pull the door handle to confirm, this will give those criminals lurking in the vicinity an opportunity.

1.The remote control battery is not charged.

2.The central control panel is broken.

3.Open the door on the other side and take a look, if it can be your handle outside the door is broken, or adjust it.

Monitor it or something.
