Hi Tomi,

Were you ever able to program a remote key fob with AlfaOBD?

I've never done that.

 

[Tomi1980]

I watched it. Only not all movies using alfaobd work on jeep. I tried to program the windows down from the key fob and it didn't work on the Cherokee.

 

[Tomi1980]

I've never done that.

I've seen the videos. I'm just asking if someone will write point by point. I'm left to do it myself. I hope I don't damage the second key because it will be bad.

 

[Tomi1980]

			I think I can program the Cherokee just like any other car. I also think that this process does not remove the remotes from memory. I wonder if there are companies that can reprogram keys in case of bad luck. Is jeep service only available? There is no one on the forum who can boast of successfully coding a remote control for Cherokee kl?

 

[Tomi1980]

I recently wrote down the radio code. It is 61317. alpha says enter 5 digits and when I enter 5 digits it shows 4 digits. I don't know why I couldn't read the radio code today. I received the message failure invalid security key. I have a suspicion that, however, alfaobd will not encode a new key.

Czy jest ktoś na forum, kto mógłby mi wysłać kod PIN do zakodowania klucza do mojego Cherokee? Mogę zapłacić za tę pomoc. Odczyt klucza RFH to 61317. Proszę o pomoc.

Imagine how much easier it would be to steal cars...

You're going to need a master locksmith for this. Or a dealership.

typo edit

I'm not afraid of car theft. Nobody knows why I have a 5 digit pin?

 

[Tomi1980]

I called the local jeep service. You won't give me a pin code. They can program the key but for a fee. Expensive service.

 

[Tomi1980]

How about this;

And there's another video about coding a new key with AlfaOBD.

Sewn well. But in the video there is a start button, not an ignition key. There is a button, and in my Cherokee, I have a key inserted. The procedure must be different. Apparently, you should replace the key with a new one and remove the already working key.

Hi Tomi,

Just to make sure we are discussing the same 'code'. There are two codes:

1. The RADIO code. This is a 4 digit code that every radio (uConnect) has built-in that must be entered on the radio screen when connected to a car the first time. The purpose is that if someone steals the radio, they cannot inset it into another car without the code. When the manufacturer puts a brand new radio in a car, the radio code is entered on the screen. The radio reads the car's VIN number (from the Body Computer through CANBUS) and saves the VIN internally in the radio in static memory (the memory survives disconnection from power). From that point on, the radio will only work on that car. The radio reads the VIN from the Body Computer every time you start the vehicle. If the VIN matches, it radio works. If it doesn't, you get a message on the radio upon startup asking for the code. This is why if you buy a used radio off, say, eBay, you need to get the radio's code because the first time you start the car after putting the radio in your dash, you will be asked for the code. Getting this code is not difficult. While you can get it from the dealer (probably with a lot of wait, hassle etc.), you can generally buy the code on eBay and other websites for ~ USD $20. The code is associated with the serial number of the radio.

2. The KEY/IGNITION code. This is a code for starting the car. I'm not 100% sure but I think this is a 5 digit code. The purpose is to prevent theft of the car. The code is used by the ignition module of the car (the key slot or push button depending on which Cherokee you have) and the key fob. If the code of the fob matches what the ignition module expects, the car starts. If not, the car doesn't start. Usually you can get this code from the dealer (here in the States they will require to see the registration of the car in your name to make sure you are the actual owner). Some locksmiths have access to do it (again, they are supposed to verify you are the actual owner of the car).


Which of the two codes are you referring to?

I'm talking about the pin code from the RFH module. For key coding. My code has 5 digits. When I entered 5 digits, however, the window says that it should be a 4-digit code. Now the question. Does the encoded key have to be replaced during encoding? I found a description of the key coding without the start/stop button system.

 

[Tomi1980]

AlfaOBD

I kind of wonder if he wrote code to attempt to connect to the BCM and another module (RFHub, anyone?) at the same time and that is what is causing the crash.

[Tomi1980]

I think it is. Ignition and connection with alfaobd. RFH module selection. Pulling out a good key and inserting a new clean key. Entering the 5-digit code I have. Maybe this is how it should be done?

 

[Tomi1980]

This way is wrong. The key cannot be removed because the new key is dead in the ignition.

Cześć Tomi,

Tak, to jest to, co napisałem w poście #81 Twojego innego wątku: Cherokee FWD pierwszy jeep w historii.

Wiele rzeczy, które są w AlfaOBD, niekoniecznie działa w Jeepie Cherokees. AlfaOBD jest przeznaczony do wielu samochodów o różnych funkcjach. W filmach na YouTube dobrze pokazano, że piloty Dodge RAM, Challenger i Charger można zaprogramować za pomocą AlfaOBD, ale nikt nie wykazał, że ten sam proces działa na Jeep Cherokee (lub być może nawet W2K GC, nie sprawdzałem). I oczywiście, jeśli użycie AlfaOBD do zaprogramowania pilota kasuje pamięć twoich aktualnych pilotów, to oczywiście będzie to duży problem. Jest to jeden z tych elementów „spróbuj na własne ryzyko”. ..

[Tomi1980]

Rozumiem. Wpisujesz 5 cyfrowy kod i AlfaOBD mówi, że powinno być 4 cyfry. 😢
[/CYTAT]
Sorry for my English. Yes. 1-I read the pin from the RFH module which has 5 digits. 2- when coding, I entered this 5-digit pin and got an error that it should be a 4-digit pin. The key is not encoded. The connection of alfaobd and obd adapter requires a key in the ignition position. So pulling out the key that I use turns off the electricity and disconnects the bcm-alfaobd connection.

 

[Tomi1980]

If I remember when they programmed my replacement at the dealer, reading the PIN was done with the FOBIK inserted in the OFF position and hazard lights activated. Activating a new FOBIK was done with the new FOBIK inserted in the RUN position and hazard lights activated.

They obviously weren't using AlfaOBD, but maybe having the key in the proper position and the hazard lights activated is the missing piece???

Thanks for another idea. But I think you used a key programmer. It may work differently. I'm afraid that without a local service from programming keys I will not do it alfaobd. There is also a program for windows appcar diagFCA. The program support says it can be done.

 

[Tomi1980]

I think that having a key inserted into the ignition, alfaobd will not encode the key. The encoded key must be in the ignition so this method does not work. I think this way is fine if you have a Cherokee with an ignition key. Then you can have the ignition on and code a blank new key.

 

[Tomi1980]

I claim that this key cannot be encoded by alfaobd.

 

[Tomi1980]

Ignition is needed for key coding, you can't remove a good coded key and insert a new key for coding because you break the connection and alfaobd!
