Open your hand if you have a hand cologne and cotton cotton I have been using it for 2 years 307 xt 2005 model ...

DOES NOT WORK WITH VERY SIMPLE POWDERS REMOVE CLEAN OR REMOVE AND CLEAN ONE OF THIS WORKER

My Old 307 also had such a problem, I tried very hard, but I could not fix it and I bought a new one. Also I Guess The Product Is More Suitable For Peugeotmarket (http://www.peugeotmarket.com/Cam-Kumanda-Dugme,LA_1426-2.html#labels=1426-2)

thank you for your help

I also had the same problem. The problem here is that the black carbon dots under the keys lose their properties, so their conductivity is lost.
As a solution, I removed the keypad and cut the aluminum foil on the carbon black spots under the keys by cutting with scissors according to these points.
