How to Re-Program Key for Citroen C3 2006 After Engine & Computer Removal

Hello

I have a question: is it possible to program the key to C3?
The engine was removed and the entire computer was disconnected, and since then the central control unit with the remote control in the key has not worked, before the repair everything worked.
Now it`s as if he lost the memory key, when I press the button, the central locking doesn`t work. Is there any sequence that needs to be done to make the new key work again?
The car is from 2006.

Thanks in advance for your help

Regards

Turn on ignition press one of the remote control buttons for about 10 seconds off. ignition, after a while they should work.
Regards,

There was this topic with Xsara recently. Same problem, same solution. If what my friend "zbyniuś" wrote doesn`t help, the only thing left to do is reprogram the keys.

Thanks for the tip. The method works. The central locking key works again

It`s true that I have c5 and this method doesn`t want to work.

So I insert the key, lock the central lock, turn the key in the ignition while keeping the lock button pressed, hold it for 10-12 seconds, return the key and release the button. It unlocks the central locking system after about 1 minute, is it ok or am I doing something wrong? At first I thought it was the battery in the remote control. I bought a new 1620 and nothing changed.

I`ll ask - in which Citroen models is the central electronics (board) the same as the one in the C3 FL (2002-2005)? The central pilot certainly doesn`t learn from Xsara.

Hello, is it possible to program a new remote control (replacement) for a Citroen C3 2006? I have already tried the ignition method but it did not help, unless there is a categorical order of operations, please help.

Does it start the car with this key?

No, first you need to program the IMMO that is integrated with the HF transmitter. Of course, you must have an appropriate remote control with precoded immo and the correct FSK or ASK modulation.
The initiation/synchronization procedures described above apply to remote controls already paired with the car.

Yes, you can, but in the PSA group, remote controls are selected by VIN number. It all depends on what BSI you have: Valeo, JCI or Siemens. The easiest way is to call the service center and ask for the chassis number (the last 8 digits are enough) and they will give you the spare part number, or you can use the hit-and-miss method. If the remote control is properly selected, the above method will work if you do not need a PIN to program it.

I do not think so. I had two Citroen cars in my family: C3 and C4 (both first generation) and it was necessary to use Lexia and provide the PIN. Of course, the key had to be a "virgin" one - it couldn`t be a key that had already been used in another car. And the right type of modulation, as the colleague mentioned above. There was a separate sequence for programming the immobilizer, and a separate (next) sequence was for programming the central locking. The above method of pressing the remote control buttons and turning on the ignition only works when the key belonging to the given car (previously programmed) is decoded.
An interesting fact is that the keys purchased from Far Eastern friends passed the test. On the website I also found a description with photos on how to recognize the modulation of the original key. The complete key (without the tip) cost €8, and cutting the tip cost €6 (also on Aliexpress - just provide the key code or take a good photo of your tip). So, for PLN 63, I had a complete key, ready to be programmed. I already did the programming myself.

Could you provide a link, because I have the original. remote control, there is no problem with reading the type of modulation with a tester, but it is worse if there is no remote control.

Don`t mislead people with such statements if you have no idea how a PSA remote control works in this vintage.

Unfortunately, the description referred to reading the markings on the key board. The offer is no longer active, but I took a photo for the archive. In my case, reading the marked part of the marking helped in ordering.

Today I looked at the key offers on this website and as I see there are more methods to distinguish the type of modulation. Unfortunately, most of them refer to reading data from the key you have.

First of all, this is only part of my statement, you obviously didn`t read it to the end, and secondly, especially for you, today I removed all the keys from the BSI in the C3 (although I didn`t have to make a virgin one, I also have a backup, so no problem) and I only coded the immobilizer to I could start the car, I took a new remote control from the drawer and started it according to the above procedure, so I think I have some idea.

Give the year of this C3 and post a photo of the remote control if possible.
I still say it`s nonsense. If it`s a penknife, it`s probably pcf7941, i.e. id46. There is no option to sync the unwritten id of the key to the bsi - that`s it. If you don`t have an older pocket knife with two buttons, your imagination has already gotten carried away.

If you say so, there`s no point in arguing because you really don`t know much (and you only know what you can find on the forum or "google"). Read up (if you have access to service bulletins) and find out whether the central locking remote control writes to the BSI or whether the BSI saves data in the remote control (do not confuse it with immo). You probably haven`t heard about cleaning the remote control (for you it`s a fantasy). I buy remote controls and keys only from reliable sources (not Chinese), from well-known companies from Piaseczno and Wodzisław or from services and I have no problems with programming or cleaning.

Provide a link to the remote control that you trained for the Citroen C3 2006 car (without immo), HF only, using the procedure given above.
You shouldn`t talk about my knowledge and skills, because you will also embarrass yourself.
I`m waiting for the data of the key you learned (HF only, no immo).

Fascinating - not Chinese - probably "American" 😂😂
I really can`t wait for you to show this pilot, because it will be a hit, usually a breakthrough in the PSA system.

What am I, a dog?
This is a public forum and I make a living from it. There is such a thing as professional ethics and trade secrets. If you run a business, you should understand this, unless you are just a regular garage owner?
If you want to acquire this knowledge, come with cash and such C3 to me and I will prove it to you.

I see that you still have a lot to learn, your posts above only prove it. You write nonsense about key programming in C3, and if someone wants more details to prove to you that you are writing nonsense, you avoid the topic using secret knowledge. The forum is open to the public, but don`t mislead people with your dogmas, because then someone will buy a remote control at an authorized dealership and synchronize it for three days, because he read on the forum that it is possible. Do you understand?
PS I have all my keys clean, I take care of them with a brush and detergents such as Baracudex, PCFProx and other more or less aggressive agents.

I just want you to indicate what type of pilot you trained this way - I mean the "from the drawer" one - it won`t ruin the market for you, will it?

Okay, there`s no need to worry, can someone tell me whether the key I ordered from Aliexpress (already on its way) can be programmed to a Citroen C3 from 2002 - I`m mainly talking about the central locking, I`ve already obtained the pin code from the Citroen service center.

If it`s a two-button one with a stiff tip and you get the correct precoding for the brand and model, after programming the immo there is a good chance that the remote control will work.

Yes, it`s a two-button one with an ID46 chip, I got the pin code from Citroen, it cost PLN 20, I only have one key, and the buttons for the central lock fell off and I wanted to re-solder them, and my soldering skills are poor, so I completely screwed it up, it would be nice if the key would talk to me,

If it doesn`t work, you can send the old original one and I can fix it.

Ok, whatever, for now I`m waiting for the shipment and apparently it`s already in Poland.

As I expected, the new Chinese key accepted the transponder code, so now I have two keys, but they are neutered because the remote controls don`t work in both of them, apparently these French have more engraved berets than us to block such nonsense to such an extent. I`ll either open it with the key or I`ll install a regular central lock for a hundred or so, apart from their stupid BSI, oh, it`s not worth talking about, but it`s a total of PLN 27, so no worries.

I`m digging the topic. I bought a remote control from Alli, of course I matched it to the original remote control. I paid PLN 80 for the code at Citroen Łódź Dealership? Password? 4 characters including one digit. I went to a specialist and got fig and poppy seeds. He can`t do anything with either of the two pilots. Code accepted but not working. What am I supposed to do now? Any hint?

I also coded the Chinese key myself, but so what if the immo coded it and I have a second key in case of W, but what I wanted most was the central locking, but unfortunately it won`t work, the French messed something up, it doesn`t make sense.

Well, that was my main goal. The central locking stopped working after the pilot fell. I replaced the battery and the remote control worked once every few times it was closed/opened. It was even measured to see if it gives a signal. And so he gives the signal. Overall, I don`t know what to think anymore, and what`s worse, I don`t know what to do. I found instructions for resetting the BSI, but I have the distinct impression that it was invented by someone for fun.

This is the "instruction"
1. Lower the driver`s window, raise the hood and make sure all devices are turned off (radio, lights, wiper, etc.)
2. Make sure all doors are closed and remove the key from the ignition.
3. Wait 3 minutes,
4. Disconnect the vehicle battery and wait 15 seconds.
5. Reconnect the vehicle battery, wait another 10 seconds (do not open the door).
6. Insert the key into the ignition (do not turn it) and turn on the parking lights through the driver`s window.
7. Turn on the ignition and check the functionality of the system and hold the lock button (lock the vehicle) on the remote control for 10 seconds.
8. Turn off the ignition, remove the key and open and then close the doors (e.g. 2 times).
9. Lock and unlock the vehicle with the remote control, then open and close the doors.
10. Start the engine (still with the window open), turn off the lights and complete the system check (check radio, wipers, etc.).

Failure to follow this procedure may result in many associated components malfunctioning.

I wonder if anyone has tried.

It looks a bit strange, but you can expect anything from the French.
