Hello guys

I have 2017 c63s. The keyless start function sometimes not working. I changed the battery in key. Nothing changed.
Its never happened ,before i installed 10,25 display from DMP. Maybe not related with the screen, but info.

 

Happens to me like every once in a while. Even took a video and ask service guys to check it out. They blamed key fob batteries but not so sure about if that’s the only cause.

 

recently ive noticed my touchless entry doesnt work sometimes.. the car fails to detect the key. i recently changed the battery so that cant be it. wondering if others have experienced the same?

 

most of the time, its because you hit one of the buttons 2 times quickly, which disables Keyless touch and go..

 

Yes agreed, i've done that a few times too 🥴

 

I meant keyless start. Not keyless entry.

 

they sometimes work in tandem.. are you saying the keyless entry works, but the keyless start doesnt ??
Do you get a "replace battery" messsage ?

 

I dont have keyless entry. I try my other key from today. lets check.

 

I have a 2017 and this happens to me as well. The key less entry works perfect sometimes, then other times it doesn't detect the key. It gets kind of frustrating. Seems like it may be a common thing. I wonder what it could be?
