I joined the forum to ask you guys a question.
Here's what happened: One day i couldn't unlock/lock/open trunk my car using the button on the key. I thought the battery was dead so i started using the spare key. The second key worked for about a week and then it stopped too. I thought the battery was dead so i replaced it. I've put new batteries in both keys but they don't work.
The little red light on the key goes on, there is no problem with the key and the battery connection.
What can it be?
Thank you for your answers.
hello to all , just joined the forum
I just bought a alfa romeo 147 with the semi auto , after placing four new tyres on it , new front brake pads ,oil filter and fresh oil , I decided to tackle the remote , the key remote was missing the battery carry , and was cracked , after looking for some time I found one new with no insides , well after splitting mine and trying to do the earth strap for the battery , and after doing so , the thing did not work ! after careful inspection , I noticed the battery was not making a positive connection to the board , I made a small spring out of a click pen (one coil ) and placed the cut end where there was a hole , IT WORKED! perfect I thought , until I tried to start
"immobilizer failure" came up , OH NO was the words that came to mind , after looking all over the net to see something came to mind ?? I had all about failed ECM BCM (body control module) and even the drivers master switch , well after thought , I remembered one IMPORTANT THING >the transponder< that little glass tube that sits near the key inside the key cover .
but as it goes as I was reading this forum , please have a look at your key fob and to see and make sure that both sides of the battery makes a connection , and the reason why the battery failed ? did you place it somewhere near a electrical field ? computer ? or was it that the battery just plain failed or been pressed so many many times that the electrical connection failed ?
the battery size I bought was a CR2032 , and the fob was from e bay (groan) made in china which took a fair bit of time to work on, the earth strap for the battery do not fit and takes a bit of time to reform.
