  mercedes/c-class/1994-2000

Hello, My 1998 C230 will not accept the infrared key to start the car. Has worked fine for quite some time. I verified the key is working with new battery and used a camera to verify that the light funtions. Can not lock or unlock car or turn key to start. Checked to insure the cars battery is in good condition lights work and so on. 

Thank you for your help. Look forward to hearing from you.
