Hellow dears, I have a used Mazda 6 2007 purchased 8 months before. Since the day I purchased, my keyless entry is not working. when i pressed lock/unlock button in the key, a light is blinking in it. But no response in the car. Car is getting started, it doesn't have any defect. I have replaced battery in th key also but on vain. I followed th proceedure explained here and no response anywhere after step 5. The keyless entry alarm symbol is flashing in the instt. cluster when the car is locked. Can anybody help me.
