A Volkswagen Van Fob Key That Did Not Work Repaired
An American friend of mine approached me in church a while ago and asked me if I can take a look at his van fob key that was completely dead: I never worked on such keys before but I was willing to give it a try.
My friend explained that when pushing the buttons, the light does not come on
and the he cannot open his van but sometimes it opens fine when he is standing very close to the van.
Based on what he said, the logical thing to do is to check the battery first and hope for the best.
The battery is CR2032 and it should read 3 volts but this one is kind of low;
it should read 3.2 and higher.
Here I am testing a brand new battery and the reading is much better so I put it in the fob key and gave it a test.
As seen in the photo, the light came on and that is enough indication for me that this fob is up and running. When I called the customer to come and pick up the key, he asked me to do an inside cleaning and make sure everything is ok.
To be honest with you, I had to go online and find out how to open it because I try to pry it open and for some reason I was not successful.
This information I required off the net suggested that I push this pin inside with a fine tool then pry it open. It seems like this pin was holding the two pieces of the fob together and that is why I was not able to get it opened.
After a long effort, I was able to open it and see the inside of it.
With a tooth brush dipped in IBA, I cleaned both sides of this board that I found inside. I put it under my microscope and checked the tiny SMD’s on it and everything checked out fine.
I found a lot of dust in there but now if you check the photo, you would see a spotless board that was ready to go back inside the fob key housing to be used once again by my friend.
