Why can t the spare mechanical key open the door?

The first possibility that the mechanical key can't open the door is that the car's central lock system is in an electronic lock state, and you need to wait for an hour or two to remove the lock before trying to unlock it. In addition, there are three possibilities: incorrect operation, faulty lock cylinder, and faulty mechanical key.

For example, the orientation of the key is wrong, and in most cases, the direction of the key is clockwise.

Unlock and lock counterclockwise. Please refer to the car manual for specific operation, there will be detailed instructions. Most car owners can use the remote control key to open the door or lock the door, less unlocking with a mechanical key, the car lock is not needed for a long time, there will be a rusty car lock, you can try to apply some oil on the car lock, lubricate, see if it can be opened, if it still can't be opened, you need to change the lock.

<> reason why the mechanical key of the car cannot be opened is: the operation is wrong; There is a problem with the lock cylinder; There is a problem with the mechanical key. The role of a car key is:

Close the windows after turning off the ignition, the windows will automatically rise and close; It is convenient to find a car in the parking lot, and the trunk automatically opens the window by remote control. Pay attention to the following when replacing the battery of the key. When removing the key, cover the screwdriver with a cloth.

to prevent the key and circuit board from being damaged after being removed by the key.

Keep the keys and circuit board dry. Do not touch the components on the board. The new battery for the car key should be the same size as the old battery.

The door can be locked counterclockwise, but the specific operation method should be subject to the vehicle manual, because the operation mode of different cars is different; If you can't open the door because of a problem with the lock cylinder, it is recommended that the owner add some oil to the lock cylinder to lubricate it, because this will cause rust inside, and it will be difficult to unlock the lock if it is not used for a long time.

This is because the door lock of the car has rusted, and this is also a very serious matter, so when we encounter this situation, we must send the car to a professional car repair shop to repair.

It is likely that the car's central locking system is electronically locked, or it may be caused by incorrect operation, or because the keys are malfunctioning, or because there is a problem with the lock cylinder.

It may be because the direction of force is wrong or the central lock system of the car is in the state of electronic lock, so you can only use the electronic lock to open the door, not the mechanical key, you need to change the state of the central lock.

It may be because the central control system is in a locked state, or it may be incorrectly operated, or there is a problem with the lock cylinder, so it will lead to the situation that the mechanical key cannot open the door.

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 whether there is a problem with the iron lever inside the door.

You this remote.

If you don't match your dad's car, you can use it if you match it with a repair shop.

The spare remote control may be out of battery, and the door will alarm when the car is forced.

Dear lz, please explain the model, the smart remote key is generally one-to-one, only the original key can be opened after the original key is locked in the car, the spare key can not be opened, (depending on the model) the biggest difference between the original key and the spare should be the original key lock car can be with a sound alarm, spare does not bring, high-end models are generally not like this, there is a situation, is there a small black spot in the door handle of your new car? (The smart key will generally be automatically unlocked when the car has a certain distance from the key) press the small black dot to see, and how many buttons does your car key have? (Lock, unlock?)

Or locked, unlocked, trunk? ）

Usually the remote control will have a small insulating plastic piece on it, and you pull it out and try it.

Does the remote control have a battery? Or there is a dead battery.

It is necessary to check the keyhole for foreign objects or a problem with the lock block.

Hello, there are two cases for this.

In the first case, when the lock lever cannot be opened from the outside with a key and the door can be pulled by pulling the lock lever or button switch from inside the car, the lock core drive lever is taken off.

In the first case, the lock lever can be driven by opening it with a key from the outside (the lock lever can be seen vertically, the horizontal movement can be heard, and the switch action sound can be heard when you see it), or the lock lever can be pulled from the inside, but the door door can not be wrenched, in this case, the door lock buckle is faulty, and the internal spring of the lock is broken or stuck, and it is flexible.

It is recommended to find a repair door for repair, after all, they will be professional.

1.Go home and get a spare key.

This is the safest and least costly option. My advice is to run more errands to punish yourself, so that you can remember this lesson, and there should be no next time.

2.Call the lock picking company** for help.

To find a lock picking company, you need to prepare valid documents such as ID cards, driver's licenses, and driving licenses. The cost is generally around 200-500, and some models are higher. But one thing you can rest assured is that the people who work in the lock picking company are masters, and they will definitely not destroy your door lock, so you don't have to change the door lock specifically.

3.It is unlocked through the in-car configuration.

For example, similar to OnStar, you can remotely unlock the lock by remote control on your mobile phone or by calling the customer service center. The premise is that your car must have similar functions, and it must be a paid membership to achieve it.

Nowadays, the doors of many cars completely use electronic door locks, even if the mechanical key is used to open the door, the lock cylinder rotates to trigger the electronic switch in the door lock, and then the electronic actuator moves to open the door. This kind of door lock key is easier to unlock than the mechanical mechanism when turning, and it doesn't take too much effort. When the battery has no electricity at all, this kind of door lock cannot be opened when the door is opened with a mechanical key and unscrewed.

It is more troublesome to open the door, so remember to charge the battery in time. How to open the door:1

Drill under the car, hook the actuator of the cabin cover with a tool from under the engine compartment, open the hatch to charge the battery or merge the battery, and then the door can be opened. 2.Still from under the engine compartment, find the electromagnetic switch of the starter on the engine, which has two large binding posts, one connected to the starter, and the other connected to the positive pole of the battery on the car.

Connect the positive pole of the spare battery to the binding post where the positive pole of the battery on the car is connected, and connect the negative pole of the spare battery to any iron place in the car body with a wire. It is equivalent to connecting to the battery of the car in parallel, and then you can open the door when there is electricity. When connecting the positive pole, you must not connect the wrong binding post, otherwise there is a risk in starting the engine, so you must be careful.

Method 3: It is to take the method of destruction, pry the door, pry the window, smash the glass, etc.

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's not, just keep looking 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.

Problems with door locks [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

If you are using a remote key, then it is very likely that the remote control key is dead or the car battery is dead, or there is a strong signal interference source around, in fact, there is a mechanical key hidden inside the remote control key.

However, if the mechanical key is available, it seems that the keyhole is not seen on the door, so it must be hidden, this is because the manufacturer deliberately hides the key jack of the door for the sake of aesthetics. At this time, you need to take a closer look, generally there is a decorative piece about the size of the key at the end of the door handle, and you can pry it open.

2. The mechanical key can't open the door.

The first possibility is that the car's central locking system is electronically locked, and you need to wait for an hour or two 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 can't turn, so if you want to solve it yourself, you can only use violent methods, that is, smashing the windows. Otherwise, you can only contact the 4S shop for repair.

3. The door can't be opened in cold weather.

The weather in the northern winter is very cold, and if it is still raining, the door locks, door handles, and door frames are likely to be frozen, so even if they are deadlifted, the doors cannot be opened, and it is easy to damage the paint and sealing strips. The solution is to pour warm water over the frozen area to make the ice melt as soon as possible, or if you are not in a hurry, just wait until noon and open the door when the temperature rises.

4. The rear door can't be opened.

If the central lock is released but the rear door cannot be opened, it is possible that the child lock switch on the door has been accidentally touched, causing the child lock on the rear door to open, so it cannot be opened from inside the car.

It is recommended that it is better to go to the 4S store to see.
