What should I do if the engine anti theft certification fails and the car can t start?? Headaches

14 years Geely Emgrand two boxes, just had lunch, came to drive to Chifeng, which Cheng thought, there was a failure of engine anti-theft certification. I've tried various methods n times, but I can't hit it, and I start it with one click. It's too much work.

There is no way to fix it. It's really a crash!!

I also encountered it, and the after-sales service gave the method, opened the hood, and the positive pole of the power cord on the right side was loose, and it was pressed tightly.

I've tried a lot of things, but it still doesn't work.

If he fails to certify, it means that the safety factor of this engine is not enough. If there is a problem with his engine, it is difficult to control it further.

So it's best to get a new engine, at least to ensure that his anti-theft certification is safe, so that he is not easy to be stolen.

Now the engine is in words, he has the engine computer, me.

In the case of inserting the key, your key is matched by the computer to recognize the card, if you answer yes, this is equivalent to giving your vehicle an anti-theft device. Auntie said that in your current situation, you can't hit the top of the train directly if you go to get two positive and negative electrodes. If it is said that the certification fails, or it is the key mismatch, then in this case, we need to use the computer to match the key of the engine accordingly.

When the engine starts, there is a sound, that is, after the sound, it will show that the engine anti-theft certification has failed, and it will be displayed after powering on after getting into the car, so check the car battery first.

Power deficits will occur. You can start it by using electricity.

The car key will appear when the battery is low. Get out of the car and press it many times to unlock, lock the car key, there is a time to use, sometimes you can't unlock the lock, the vehicle does not respond, that is, the key is low, change the battery for the key.

If the problem is not solved. Then check the engine start-up insurance and engine anti-theft insurance of the gas car. If you won't look for it, press it one by one to see if it's loose, or wipe it clean to see if it's blackened.

The most common thing about this is that low battery is the most likely problem.

Hello, there may be a problem with the key (such as an illegal key or the key is damaged and cannot be read), there is also a problem with the vehicle computer, and then there is a problem with the wiring. For the sake of driving safety, it is recommended to go to a professional 4S shop for maintenance. Hope mine can help you.

I also had this problem in the car a few days ago, because I was on a business trip, the car was not opened for two months, and the switch of my luggage rack searchlight was directly on the battery, so the car battery was discharged for a long time, and then there was no ignition, engine anti-theft certification failure, electronic steering lock lock lock failure and other problems, and then went to the 4S store to change a battery, the problem was solved.

Summary. Hello dear! <>

The reason for the failure of the anti-theft authentication when the car is ignited is that the engine anti-theft authentication fails because the car key is not detected, and most of this situation occurs because the car key is out of power or there is a problem with the receiving module. When this happens, riders should check their car keys.

The remote key of the car has a module specially used to start the engine, if the key has electricity but the module is broken, the engine will not start.

What happens when the car is ignited and shows that the anti-theft authentication fails.

Hello to Nachong! <>

The reason for the failure of the anti-theft authentication when the car is ignited is that the engine anti-theft authentication is not detected by the comic family, and most of the reasons for this situation are that the car key is out of power or there is a problem with the receiving module. When this happens, riders should check their car keys.

The remote control key of the car has a module specially used to start the engine, if the key has electricity but the module is broken, then the engine will not start.

Hello dear! <>

Your situation can be solved by simply changing the key battery. Changing the battery for your car's key fob is very simple, just pry open the case and take out the old battery and replace it with a new one. If your car is equipped with a one-button start system, you can start the engine without inserting a key after getting into the car; Cars equipped with a one-button start system have a special position for sensing the key in the car, and the key can be placed in this sensing position when the key is out of power, so that it can also start the lead blade of the engine.

If the key is out of battery, it is recommended that riders immediately go to the change to change the battery, so as to avoid delaying their own car.

Open the door and sit in the main driver's seat in the car, take out the car remote control key, paste it on the one-key start button, hold it for more than 30 seconds, and then continue to paste the one-key start button and press the unlock key on the remote control key. You can press the lock button and the trunk button several times or more times. If you try several times and still can't remove the alarm that the engine immobilizer certification failed, go to the repair shop to take a look.

There are several reasons for engine anti-theft certification failure:

1. The internal chip of the key is not matched and not locked (not locked in the anti-theft control unit).

2. Anti-theft reading coil failure.

3. The communication between the anti-theft coil and the anti-theft control unit is faulty.

4. There is no match between the internal fault of the anti-theft control unit and the communication fault of the engine control unit.

5. Electromagnetic interference, etc.

6. If you want to solve it, first read the fault code, lock the fault point according to the content of the fault code, and read the data stream to see the current status of each system.

Like this case, check if the remote control's battery is charged? Otherwise, replace the remote control battery. Check if the signal of the remote control is normal?

Expansion: 1. The one-button start device is a part of the smart car, which is a button device to realize the simple start process, and can also be turned off, and the device can be modified at the position of the original car key lock, or it can be modified independently of the panel. Its starting mode is a software one-button start, and there are three main points to pay attention to when installing a one-button start system for cars (plug line under the ignition switch, the position of the button and the handling of the direction lock), which has a variety of functions.

2. One-button startIn general, there are also what we usually call a key with serrations or grooves in the smart key, which is used to prevent the failure of the one-button start function and start it by mechanical start. The car with the one-button start function generally does not need to insert the key, but there is a position to insert the key (its function is to prevent the failure of the one-button start function, use the key to start) The one-button start device of the car is a part of the smart car, and it is a button device to realize the simple ignition process, and it can also be turned off at the same time, and the device can be modified at the position of the original car key lock, and can also be modified independently of the panel. Now many cars already have this smart device to increase market competitiveness, whether it is a high or low configuration of the vehicle can be installed, but a single one-button start is of little significance, and the use of the PKE intelligent system will show the necessity of intelligent modification.

At present, there are about 100 domestic manufacturers of intelligent one-button start. Most of them are transformed from the manufacturers of immobilizers, with the gradual rise in market demand, one-key start has gradually become a must-install equipment for cars, and the product has gradually fallen back, gradually becoming a popular product, and professional installers are needed to successfully modify its various functions.

Open the door and sit in the main driver's seat in the car, take out the car remote control key, paste it on the one-button start button, hold it for more than 30 seconds, and then.

Continue to stick the one-button start button and press the unlock button on the key fob. You can press the lock button and the trunk button several times or more times.

If you try several times and still can't remove the alarm of engine immobilizer certification failure, you can pull the engine under the dashboard.

The lid handle of the motor compartment, get out of the car and go around the front of the car, face the car logo, squat down, probe to look into the gap of the three chrome strips, and find it.

Conceal the handle, reach in and lift the head cover, there is a horizontal strut lying on the left side of the engine compartment, and lift the struts out of the clip.

The bayonet at the top of the pole is snapped into the recess on the left edge of the headcap and holds the headcap. You go to find the outer 6-angle wrench of M12, and then, the probe finds the positive and negative terminal posts of the battery, pulls open the plastic cover covering the negative electrode with a hand, and then fixes the negative electrode.

Unscrew the clamp nut with an M12 outer 6 angle wrench, loosen the clamp from the binding post, hold it for 1-2 minutes, and then put the clamp sleeve.

Most of the engine anti-theft certification failures have two original causes:

One is due to the problem of matching the remote control key and the engine computer. There are many reasons for this: for example, there is electromagnetic interference nearby, there is a large power supply nearby, it is in a very open area, and so on.

The second is that the front windshield film has water (this reason is quite a lot), and the water will flow down the glass into the central control. When pasting the slippery film, you must tell the master to pay attention to it, and it is best to put a towel on the center console.

In the above situation, most of the phenomena are brake failure, the steering wheel becomes heavy, and the ignition does not catch the car. This is due to the start of the engine anti-theft system, the car is cut off from oil and power, and there is no oil pressure when it can't catch fire, so the brakes and steering power basically stop working.

For cars that have been equipped with an engine immobilizer locking system; Even if a car thief can open the door, he will not be able to drive away the car. A typical engine immobilizer works like this: the car ignition key is equipped with electronic chips, each of which is equipped with a fixed ID.

First of all, the situation needs to be reflected to the 4S shop of the car, and then the 4S shop uses the maintenance computer to solve, generally this phenomenon occurs, most of them are because the car brake fails, and it is necessary to check whether the car brake assembly is faulty, and the fault can be repaired to continue to use. The solution to the failure of car anti-theft authentication and cannot ignite is introduced as follows: 1. Introduction 1:

You can try to replace the battery of the remote control, and it may also be equipped with a one-button start function failure or it may be that the body control module or circuit is faulty, and you need to contact the repair shop for testing and maintenance, and you can continue to use it after repairing the fault. 2. Introduction 2: The ignition system of the car is a system in which the ignition engine is ignited in order to work normally, and the spark plug is supplied with sufficient high voltage according to the ignition sequence of each cylinder, and the spark plug produces a strong enough spark to ignite the combustible mixed gas, and the electronic ignition system is reduced to fire by the electronic control device according to the working state of the car, so that the engine is always kept in an ideal working condition.

When the car is ignited, the anti-theft authentication fails to be displayed, which is probably caused by the remote control battery on the car key not being charged. Replacing the battery can be solved.
