Vectra C Key Replacement Issues: Immobilizer Error, LED On, Car Icon & Padlock, Immo Coil Repair

Hello,
I was replacing the button on the VECTRY C key. After pressing the buttons, the LED is on. However, I accidentally peeled off the immo coil. And now, after inserting the key into the ignition, the car icon with the padlock lights up and you can not start. Does this immmo coil have to be glued to the plate? Because she probably isn't soldering to her.
Could she decode ??

Soldered.

Measure the resistance of the coil as it is infinity, buy the same key and solder the coil.

Hmm ... it's weak ... no conductive terminals come out of this coil, i.e. at least I can't see them. hmh what's the cheapest way to fix this? buy a new key with such a coil and programming somehow / somewhere?

I have the impression that you have no idea what you are doing. The coil is soldered in places marked with red arrows. And there are solder fields there.

And how do I measure how nothing conductive is sticking out of the coil?

Added after 3 [minutes]:

And ok. On the board I have as if clamping clamps from this coil ...... so I won't save it anymore. or replacing the key? For example, if I buy a used one, how much can it cost to reprogram? Unless I can do it in a "home" way?

Transfer the coil from another remote control to the guest what he can solder and after the problem, nothing more.

hm i don't need to program it to immo in the car?

There's no need to. This coil is just an antenna.

hmh ok, i.e. the coil must be from the same remote control? i.e. also vectra c?

What parameters do the coils have in these pilots?
Can it be like this: https://www.olx.pl/oferta/cewka-indukcyjna-transpondera-pilota-kluczyka-CID5-ID8hH2Z.html

dbs buy the pilot, solder the coil and close the topic.

If the guest does not know what he is selling, do not buy from him, you can also come to the key service after Christmas and it will also overwhelm you.

The pilot costs PLN 100-200.
I am looking for the cheapest option.

Do not do the barn key without the ignition is 30-45 PLN. In addition, parts for VC do not belong to the Fiat 126p price shelf.

What about coil reflector?
I also see help you want him
Look, buy the cheapest key, I don't know how many 2 or 3 buttons.
On the board you have the layout you need to transfer yours to the bought one
The topic is so simple and you write about the coils

It may be a simple topic, but if someone asks such a question, there is a poor chance that he would put the SMD chip back.

Well, the immo coil broke maybe out of curiosity or maybe out of knowledge.
Everyone needs money, but curiosity also costs money.
Cheap does not mean good and good does not mean that it will be cheap

Enter the keyword 'Opel coil' in the Allegro search engine and there are plenty of them, by the way you'll satisfy your curiosity about the leads. I also have a remote control board in which the transmitter system has failed, so the antenna (coil) is ok. It is responsible only for the immo, specifically the antenna that connects to the immobox loop on the ignition switch. The antenna of the remote control central locking is made on the laminate in the form of a printed circuit. If you are not tired in soldering, do not move this pilot, because you will cause yourself more poverty than now.
