Astra G, central locking does not respond to the remote control

Hello

In my astra, the central locking does not respond to the remote control (in the key), closing and opening with the key works correctly. The battery in the key is new, the LED lights up when the buttons are pressed.
I found on the ops forum how to synchronize the key and program it, I did it according to. this manual:

1. ignition key
2. After 30 sec. press any of the buttons, the lock should close and open.

So this recipe does not work, I wonder if there is a radio receiver in this car that transmits signals to the central locking controller. From what I've heard, it's supposedly already implemented in the driver itself.

I'm out of ideas...

it's just tech.
Some models don't want to sync like that.
(30s is redundant time) click right away.

Hello,
I have the same problem with the central locking in the astra G.
The remote won't program itself since I bought the car.
With the key, the central works normally, the battery is new, etc.

Due to the fact that there is a mess in the electrical system (no backlight of the center console, the display does not work)
I got the idea that maybe the control unit + does not reach after turning the ignition switch (logically, the control unit must know when the key is turned, since programming requires the ignition to be turned on).
Unfortunately, this is only my theory and that's why I would like to ask for opinions and possibly a wiring diagram for the control panel.

And the practice is that after turning on the ignition, you must immediately press close / open
And that's 10 seconds

Unfortunately, it doesn't work either :)

I would like to add that the interior lighting is not on yet and I do not know if it can also have an impact (the switchboard sees that, for example, the door is open).
Does anyone have a schematic for this unit??? I searched on google but couldn't find it.

You probably won't find a diagram of the centalki,
Interior light not working at all? Is it after turning on manually, opening the door with the key or opening the door ajar?
I do not know exactly how in Astra, but in Vectra B and C or Omega B and BFL (so-called C) the interior lighting is controlled by the lock control unit. If it does not light up in any situation - check the fuses, I had a similar number in Omega - the central one opened the door for me with the key - it did not respond to the remote control, the display was not lit - the fuse was blown.

Another option is that the remote control is not programmed to the control unit - the procedure described above is only synchronization - you will not program the remote control even if you buy a new one - you need to go to the TECH

It's not on at all, fuses are fine.

Below you have the Astra diagrams - get to the control unit and check the constant and after ignition voltages.

EDIT:

There is no switchboard in these diagrams - it should be around the 1900 line

Unfortunately, these are the only diagrams I have come across.

The radio turns off, the buzzer does not work

Disconnect the radio plug and try to synchronize.

Unfortunately, it doesn't help either, but I still don't see the connection, because my cube only enters the mass, + from the battery and + after the ignition.

P.S. does anyone know if the scheme from the vectra B / zafira will be the same as in the astra?

Added after 57 [minutes]:

I got to the CZ controller and there is no cable that would give + after the ignition.
There are two red cables - a thicker one, on which there is 12v all the time, and a thin red one, and here in my opinion it should be + after the ignition switch, but I'm not sure and I don't want to risk it.

The diagram from the zafira should match, there should be a plus on the thin red wire after inserting the key. Check fuse 1.15 in the older model or 3.21 in the newer one (with small fuses)

Fuses ok, but I bridged for a while and synchronized and the control panel works with the remote control now just pull the cable from the ignition switch under the thinner red one and it will be ok. Thanks for the answers.

After the fragments of the diagram, I see that + after the ignition switch should be on the black cable from fuse 1.15 which goes through the X1 connector to the control panel

Well, in the diagram from zafira or vectra b has red from the x1 connector. I don't have a black cable at all

The point is that it works - you can look at the connectors one by one if you want to have everything as in the original, and if you don't care, the cable will be shortened and it will also be OK.
Regards

If I can't, I'm going to hell I still have a few bugs left to fix.
It is a pity that I found the diagrams for Astra G only in Italian and a few pages in PL.

Colleagues, for the future, this programming is so that the ignition is turned on and then the door closing button is pressed several times until the control panel works and it should be ok. and when it comes to the diagrams of this vehicle, you need to find TIS Opel on torrents and there will be diagrams for each car. Regards and enjoy the installation

I will not start a new thread, because the topic of synchronization of the astra remote has already been rolled out many times.

I have an Astra 1.4 MID '99 and a factory immobilizer and car alarm (the word SILICON on the remote control - if it helps, I can post a photo of the remote control) the way of turning the key to position 2 and pressing the buttons on the remote control does not work. I didn't have a chance to sync before because it was working fine all the time. The remote activated the central locking and activated the alarm.

How did the problem occur: the car stood for several days unused and the battery died, I opened the key, the car was able to start by connecting the battery from another car, the alarm began to howl, the alarm flashed, the direction indicators and the alarm / immobilizer indicator light on the dashboard, the buttons on the remote control stopped responding, I turned it off under the hood of the siren with a small key, it stopped howling, continued to flash. Under the board below the steering wheel, I found a button on the cable, after pressing it several times, the direction indicators stopped flashing, similarly to the light on the dashboard.

I tried to press the button under the board, after pressing it, the car makes a sound as it was previously made when activating the alarm with the remote control and blinks once with the direction indicators. What is this button for?

I replaced the battery in the remote control with a new one, also I am not able to synchronize the remote control. Has anyone an idea what could be wrong?

Hello.
I read most of the advice on how to set the central locking, i.e. how to program the key, but it didn't work - maybe some suggestions to do it?
1 I get in I close the door I wait 30 seconds I put the key in position 2, the lights come on - I press close and nothing.
as above, the same and I press open and also nothing-add lights up in the remote control for about 3 sec.
2. I get in, close the door, lock it with the button, central closes, insert the key - turn it until the lights come on, wait 30 seconds, press close and nothing - I do the same with open and also lime - if I do it within 10 seconds, no effect either.

I also came to the fact that while holding one of the buttons, the LED blinks for 20 seconds. Does anyone know if in this case it is not synchronization and how to program it to the car?

Hello
The LED blinks when the pilot tries to establish communication with the control panel. When it succeeds or 20 seconds pass, the action is interrupted.
I synchronize the remote as described. I turn the key and press any button. The door can be open. It always works when the battery is good.

The remote control is soldered. There is still no communication. Is there a replacement of the module with the remote control? Is there a reset that will release perhaps blocked lines for my remote control?

hello, I have an opel astra 2 from 99 I have a problem with the central remote control programming is rather ok because I close the windows with the key but only when it is inserted into the door and I can't close it with the remote control and open it what can you advise me what to do to make the remote control close the door

Hello opel astra 17 dti
Check the battery and then synchronize the remote control according to the instructions. Closing the windows with the key has nothing to do with the remote control.

Hello ! after a long struggle with the coding of the remote control, I finally got it..


PATENT AS FUCK..

ASTRA G 2.0DTL 98r 3 doors.
MOST IMPORTANT!!!!! ___>> DISCONNECT BUCKET FROM THE RADIO !!

On this page there is a description of how to close the windows with the remote control:

Hello, I, in turn, have such a problem with the key that it "forgets" what I program it ... It just stops working and I have to put it back in the ignition, program the bolts, se jump, etc. And it works for a day two longer until finally the ass, it stops working and either: The LED is on and I have to program it (it can't be done) or the LED is not on, I have to disassemble it, put it back together and it works, it is on, but I have to program it again. I do not know what kaman, do I have a new switchboard to make? Sorry if it's not in Polish
