Can I buy a new car and give me an old key to it as a private car?

**According to the new car** to you, this is obviously not in line with the pricing standards of a product, this car is at least a private car, the key is worn so seriously, you can see the degree of depreciation shows that this test drive is used more times, and the dishonesty of the merchant will bring you unnecessary trouble.

It's just a matter of packaging. If it's just a shell, you can't judge it at all. It may be the wear and tear caused by moving around together.

Trick 1: Look at the girders. Opening the hood, we can see two girders, one is the girder that connects the so-called "crash bar", and the other is the secondary girder that supports the fender, water tank, etc., check the shape of the two beams, the surface flatness, whether there are cracks, etc., and whether the edge welds are well fitted.

Trick 2: See if the inside of the engine compartment is the same as the old and new. As the name suggests, the inside of the engine compartment should be the same if the old and new should not be cleaned before, if the parts are new and old, and a part of the engine compartment is collectively replaced, then it should be considered whether it has suffered a large impact.

Trick 3: Observe the welding joints of the joint part of the radiator frame and the longitudinal beam on the Jizi plate The original solder joints should be slightly round and slightly concave, if it is found that the solder joints are convex, there are spot welds of different sizes, such as spot welding of different sizes, the solder joints are rough, irregular and uneven, it indicates that it is a trace of re-welding, which proves that the radiator frame has been impacted.

Trick 4: Observe the dash panel See whether the upper edge of the dash panel between the engine compartment and the partition plate in the cab is straight. If there are obvious traces of repair on the upper edge of the front stupid coaming, it can be judged that there is a major accident.

If it is a key, it means that the car is a test drive.

The heart of him, he gave you a handful, and asked for ten, which means that there is something wrong with his car.

OK. Key Classification:

With the development of automobile manufacturing technology, people are accustomed to refer to the equipment that opens the door of the car and starts the engine as the key.

1. Pure mechanical lock key for the car.

Key car mechanical locks are the most common application and the earliest car anti-theft locks, which are rarely used alone in mid-to-high-end cars. Mechanical locks mainly play the role of restricting the operation of the vehicle, and can provide limited help in anti-theft, which is difficult to resist. The average car thief can pick the steering wheel lock in tens of seconds.

2. Electronic anti-theft lock key.

The main functions of the one-way electronic anti-theft system are: opening and closing the door of the car, vibrating or illegally opening the door alarm, etc., and there are also some brands of products that have added some functions according to the needs of customers: using the electronic remote control to complete the engine start, stalling, etc.

The electronic remote control key is used in the car, if you re-configure the car key, the code of the new car key is enabled, the original car key code is invalid, this is more high-end than the door key. Of course, the original remote control key with the same mechanical key can open the car door, but can not start the engine, if your car key is lost, someone can pick up your key, he can open your car door, just can't drive your car, so for complete security, with the anti-theft door is the same, you need to replace the entire car lock system. This way, even if someone picks up your car keys, they won't be able to get into your car.

This is not necessarily the specific need to see what model you are, now the car is using the electronic remote control key, if you re-configure the car key, the new car key code is enabled, the original car key code is invalid, mind you contact the 4S shop for details.

The car key is lost with the original one that cannot be used. The following is an introduction to the precautions for the use of car keys and the introduction of new keys

Equipped with a new key:

Directly carry the original remote control key of the vehicle to the unlocking company for matching, or directly to the after-sales service department for matching, and the key can be matched directly if the key is not lost. If it is lost, it cannot be directly matched with the vehicle key, and the central lock of the vehicle needs to be replaced.

Release the key immediately after ignition:

When the driver is on fire in the car, he should release the key immediately, and do not keep twisting the key, which will damage the engine strip. Putting the smart car key and the mobile phone together often will inevitably lead to the failure of the smart car key, and the battery life of the smart car key is about 1 year. Due to the frequency of use of car keys, the consumption of batteries is also different; Using a car key at different distances will consume different amounts of electricity.

Be very cautious about changing the battery of the smart car key, once there is a mistake, the circuit board in the key will burn out.

If you can use it, in general, if the key is lost. It is all equipped with a mechanical key or remote control key, which is not expensive. Depending on the fare, ** minimum from 200.

If you change groups, the cost is too high. So it's basically just a key change. New and old keys are universal.

If it is a mechanical lock, the lock of the car has not been changed or disassembled, just a copy of the original old key can still be used.

If it is a computer version, a high-end car lock with a chip, after reconstituting a key, the old key cannot be used, and it is not easy to unlock the lock, and the car lock cannot be opened.

The car comes with a new key, and if it is the same as the old one, then the old key is completely usable.

The car can also be used after it is equipped with a new key, whether it is a new key or an old key.

If the car has a chip, it can be used the same whether it is equipped with a new key or an old key. If the chip changes, then it may not be used.

Whether it can be used depends on whether the old key is deleted with the equipment when the key is matched, if it is not deleted, it can be used, if the key is lost, it must be deleted, so as not to be picked up by others, causing unnecessary losses.

The car is equipped with a new key, the old key can still be used, the new key is the same as the old key, and the old key will not be invalid.

It works. Because the new key is also based on the old key, it is matched for fear of loss, so the old key can still be used.

The car is equipped with a new key, and the old car key can still be used, but it is just an extra one.

If you have a new key, you can still use the old one. As long as it's not bad.

Yes, you can check the car manual, according to the requirements of the key placed in a special position can be on the car, if the car has a starting keyhole, take out the mechanical key in the remote control and insert it into the start.

The car is equipped with a new key, and of course it can be used, because after all, he only has one, but he has not changed.

The car is equipped with a new key, can the old key still be used? The car is equipped with a new key, and it can still be used in the case of changing the lock.

Change the anti-theft code, the old key can not be ignited, but you can open the door and trunk, if you want to make the old key completely useless, then you must change the lock cylinder.

Yes, if the chip doesn't move, it's no problem.

Generally speaking, if you have a chip, you can't use it.

Whether you choose a 4S store or a professional car key service platform, you must choose a larger, well-known, and best warranty, because the key is not a good thing, and I personally think that the car lock treasure is good.

The car is equipped with a new key, and of course the old key can still be used, because the new key is carved out of the model of the old key.

After the new key is equipped, the old key will become invalid, but this failure means that the vehicle cannot be started, and the door can still be opened through the old key because the door has a mechanical lock. Therefore, for safety reasons, it is safest to replace the lock cylinder of the whole car, when the lock cylinder and key are new, there is no need to worry about the old key to open the door. However, the cost of replacing the lock cylinder of the whole car is higher, at least a few thousand yuan, and this situation needs to be considered by the owner himself.

It's still usable, but it's not as convenient as a new key!

I said that after your car is equipped with a new key, it must be able to be used normally, because we are only equipped with a key, and our lock is not replaced, in this case, it must be able to work normally.

The car is equipped with a new key, can the old key still be used? You can rest assured that the new key is the same as the old one.

Now the car is using the electronic remote control key, if you re-configure the car key, the new car key code is enabled, the original car key code will be invalid, this is more high-end than the door key.

Of course, the original remote control key with the same mechanical key can open the car door, but can not start the engine, if your car key is lost, someone can pick up your key, he can open your car door, just can't drive your car, so for complete security, with the anti-theft door is the same, you need to replace the entire car lock system.

Even if someone else picks up your car keys, they won't be able to get into your car.

Officially because of the above reasons, so the choice of the way with the car key is also very critical, if in an irregular place with a car key, they can not only leave the embryo of the mechanical key, but also may leave your remote control key code, the next will be a life of self-evident. So be cautious.

First of all, I want to popularize it with you, 4S stores are not as reliable as everyone thinks, thinking that they actually find a lot of business to find small auto parts stores outside to complete, and the ** of 4S stores is not cheap, so it is recommended not to blindly believe, of course, it is not that all 4S stores are like this, there are still very formal.

Whether you choose a 4S store or a professional car grinding key service platform, you must choose a larger, well-known, and preferably one with a warranty.

Yes, because the key is not out of order, I personally think the car lock treasure is good.

In short, most cars are now remote keys, as long as you have a new remote control key, the original remote control key will definitely be invalid, but in the case of not changing the lock cylinder, do not put things in the car casually.
