Thought I would share this as it might help someone else as these fobs are expensive or you might be in a desperate situation away from home.
If your key fob stops working, open it up and make sure the plastic shroud that covers the chip is fully attach to the internal circuit board. If it is not, try this simple fix?
Fix:
In a pinch tear off a small piece of paper or napkin and fold it over so it is 6x thick or so and about a half inch square then, put it on top of the tallest part of plastic shield (the round dome) that covers chip, reclose fob and see if it works? You might need to reduce or increase the folds in the paper for the correct pressure as too little or too much pressure on plastic shroud will result in it not working.
Let me explain:
My fob had not been responding well for a long time. So, when do I replace the battery… of course when I was on a big trip; three hours away from home. After replacing the battery, the fob did not work at all, and the car would not start. After retrying with the old battery and dicking with it for 20 minutes I got it to start sometimes but then it became unresponsive again, so what the heck was going on?
Bottom line:
I came to discover the plastic shroud/shield that surrounds the chip in the internal circuit in the fob needs to be firmly against the circuit board. To do this, I placed a torn up piece of a napkin on the very top (the round dome) of the plastic shild and it provided enough pressure when snapping the fob back together that it worked. One thing to note is that if it’s too tight it will not work either. I still need to glue this down,but it has been working for two months now. My assumption is that it was bit loose before and then became completely loose when I pried open the fob to get the battery out.
Well pretty goofy but worked for me and could possible save someone else?
