Alfa Romeo should sponsor you. It is not attractive to own a car brand if there are no solutions for repair jobs. You make a difference!
Keep up the great work!
Wow, thanks! It's really good to me to know that! Please share this with your friends!
Very useful thanks Bruno
Thank you very much! Please share with your friends
Thanks for this video, these keys are a little fragile but they do the job well. The hook piece for the key ring can break or disappear too. Cheers
Hello. I'd say they are average. Some key fobs are way worse than this one. The previous and after for example.
And on other car brands, some are really awful.
Thanks for watching, share with your friends
Very good
Thank you very much! Share with your friends
Hello everyone I am professionally making keys including car Keyes. I just wanted to confirm to everyone that this video is actually really good and accurate. I'd only add that battery used in it is CR2032 for those who didn't know, and for reprogramming it's better to turn on car's battery and then hold lock button for around 15 seconds
Hi Nemanja, what did you mean exactly by turning on car's battery before holding lock button?
I just changed my battery on my giulietta key and it worked immediately after but after an hour or so the key did not work again.. do you think it has to be reprogrammed or it is a different issue?

Olá você pode me ajudar SFF?
Tenho um Lancia Lybra, já troquei a pilha da chave, ela acende mas não abre nem tranca as portas, será o transponder?? Ou poderá estar codificada??
Obrigado
Correction: on the Renault Clio II it needs the battery on the key fob for the transponder.
Last month my key stopped working; I replaced the battery but no dice, I was told that the chip on the board inside the key doesn't like it if the key is dropped, could I just order a new key with the board and put it together with my current transponder and key part?
Thank you for your quality videos regarding Alfas :)
Hello. Yes, the battery is only for the remote lock part. The little chip is for the transponder immobilizer and it does not require power.
A new key as to be always programmed with all the other keys you may have
Hey champ. I just bought a $1000 Alfa 147 twin spark with two sets of keys.
One remote works and just changed the battery as per your instructions on the other. Tried to pair it to the car by holding down a button for a long time but it’s still not working. The red light on the key flashes.
Any ideas.
Hello. The best thing is to re code them with the diagnosis tool. Make sure to do that with all the existing keys.
Ora boas caro colega, então é o seguinte fiz todos os passos mencionados no vídeos medição da bateria esta a 3.1v e inclusive substitui por outra na mesma, fiz a questão de aguentar o botão mas sempre sem efeito a questão é que desde que adquiri o carro o mesmo nunca me fechou ou abriu na chave será problema na própria chave ou algum módulo de fecho central no própria carro ? A viatura é um alfa 147 jtd 115cv a chave do mesmo contém abertura e fecho do carro e abertura de mala, desde já obrigado pelas dicas sem dúvida um canal a seguir visto ter bastante informação sobre alfa Romeo.
Olá. Eu tenho também o canal totalmente em português com o mesmo conteúdo se for melhor para si
Basta procurar por Bruno Crespo.
O melhor procedimento é fazer diagnóstico para perceber se o carro reconhece o comando e se não, fazer uma sincronização. É preciso os códigos.
Hey thanks for the video my problem car doesn’t respond for the remote signal, I checked the remote it’s working. I think something wrong with the signal receiver, do you have any idea to fix this problem?
Hello. It depends a lot on the car. Make nas model,
Same happened to me, did you find the solve?
hi, i have a 156 facelift i want to ask if you also have a problem with low range remote control. there is no way to solve it
Hello. Yes, the range is not that great. Mine sometimes drives me crazy. I did not had time yet to study the issue. Sorry... But a fresh battery (not fake) normally solves it.
hello, I have a 2002 156 1.9 8v jtd, (interior face lift) one day I was driving to work and after turning off the car i could not close the door with the remote (i opened it no problem) i was trying to synchronise it by holding the button but it dosn't work, it flashes the led on the key for 10-15 seconds and nothing happens, I swapped batteries from my other key (wich works on both batteries and without synchronizing) any sugestions?
Hello. Most of the times the problems is the microswitch it self, the weld crack up. And the battery must be a hi quality one.
Do far never saw any issues with the remote unit in terms of remote access
Common practice is to put the key in the car and turn on A/C but not the engine, and then hold lock button for around 20 seconds
I lost my keys to my car 156 (99) any suggestions for cheap keys that I can buy
Hello. Any Fiat/Alfa style key will do as long as it is the same transponder chip type.
For coding you must have the codes too.
Any suggestions on how to get the codes
Any Alfa Romeo dealership will be able. They provide a card with the electronic and mechanical code. The electronic for the transponder keys and the mechanical for the remote.
All keys must be coded at three same session. Not doing so the ones that are out will never ever will be able to be recoded
I changed my battery and kept pushing the button but it did nothing how long do i have to keep the button pressed to sync?
Hello. 3 to 5 seconds is enough
@@alfaromeonoproblem i kept holding each button for more than a minute nothing happened
A problem with the key or the car. Maybe it has to be re coded
@@alfaromeonoproblem hopefully not 🫥 ill try disconnecting the main battery from the car and draining the system of all electricity, then ill leave it for about 15min disconnected and reconect it mybe it will reset the system, hopefully not fk something up in the mean time
Hope it works
Bom dia. para sincronizar a chave para um giullieta não existe um procedimento do genero para sincronizar o comando? cumprimentos.
Olá. Não, é tudo através do aparelho de diagnóstico. Tenho o canal em português se for melhor para si
@@alfaromeonoproblem obrigado pela resposta. É feito com o multiecuscan suponho?
Ou com um aparelho de diagnóstico equivalente, como a Autel.
@@alfaromeonoproblem algum modelo em especifico?
Qualquer máquina Autel com software original autel faz isso
Dont work at mine 147
Hello. Can you tell me more?
@@alfaromeonoproblem hi... i just went to my car it opened without any problem.. i was at my destination i stepped out.. wanted to close but didnt react... i changed the battery but didnt helped,,, now it doesnt work neither close or open...only manual
Ok, but with manual locks and unlocks all doors, right? If so is you key fob with some issue. But you need to confirm it with a good diagnosis machine. To see if the cars recognises a button is being pressed. If it recognises and doesn't do it, the issue is on the car somewhere. Body computer maybe
I have one key without any buttons for my 2004 156. Can I replace it with one with buttons? And will they work?
hello, if the button fell off you can repair it. if you have a key without remote at all you can add it but you have to have the code for it, its different for the transponder code. it is a seecond code
