I took delivery of a new w205 C250 just over a week ago and it was trying fine until last night. I had my key in the pocket and walk near the car and pulled the handle of the driver side with the attempt of going in. No response was happening and I tried with the boot which was also not functioning. I try the second key and it did not work either.

i took the car back this morning to the dealer and they said I have to leave the car for a whole day to look at. The service manager suspected it is the sensor unit inside the car is not working. I am very disappointing with this as this is a relatively expensive car and it is only on the road for a week.

Did any gents of ladies in the forum has similar experience? Love to hear from you if you have.

I recently had a C300 as a loaner while my car was in the shop. The car would not recognize the fob almost half the time. I got very good at using the emergency key to get in the car. I changed batteries and it made no difference.

There is a possibility that you are getting interference from a smartphone if you're using one. Other than that, have your dealer check for any updates that might be available for your car.

Thanks. I do use smart phone but not sure it is related. The dealer is taking back for full check.
