I am blocking megane

The aluto is blocking and I do not know what to do is a megane reindeer and you can only do with the key and this is done and there is no case that it starts in another way since it blocks everything, please I need urgent help I do not know what I need the car and the mechanics that have gone to see it do not know how to handle the matter only tell me that I have to send it value is 400,000 app and no
information

Look with a scanner you can unlock it if the problem is that the computer is blocked, I did not open a problem, if it is your key, you will have to buy one if you do not have both, or the other option at least here in Chile is that they unlock the keys and their codes and it works like a normal car, this is done by the places where you send do not make keys if you do not lose the houses. There is another option but it only works in cases counted with the fingers of one hand, disconnect the batterium for 30 seconds or a minute, and try to see what happens.

Let's see my friend ...
If what you want is for the vehicle to turn on is very easy, take a duplicate to the car key, no matter if it is of any special material, the important thing is that the carving is exactly the same. Then when you have the key if you may have the black part of the damaged key, where the central block buttons are, look for the way to open the key, very carefully, take out a kind of black pebble that is put to pressure at the base of the key plastic.
Then put the key (duplicate) about the glass you took around the start switch and put the "ON" ignition
then turn on your vehicle and now.
There what you are doing is that your vehicle is equipped with immobilizer, (in Renault it is very specific to this system and is classified by letters, a, b, c, d, ... z, but this always works) and every time you put the key there inside it has a crystal called "transponder" that emits a code to the antenna (Transciber) that is circularly around the Start switch. This code every time you intuit the key and then you take it changes, I mean that it will only recognize you with the last code that I record the transponder, even if you buy the key will not turn you on, since you have to program the key to the immobilizer, and the PCM.
What they do in most cases is to leave the car if they immide and put any key, which makes your vehicle vulnerable to a violation.

luck.
