So, here is the story and sorry for my english...

I took my car to a detailing center and they took off the Recaro seats and the carpet and also disconnected the battery, after the cleaning the install everything, plugged the airbag sensor and all the cables, connected the battery, waited 15 minutes and them try to move the car.

Tried to start the car, the display indicate this: KEY LESS OPERATING SYSTEM SERVICE REQUIRED, tried to start using the metal key introducing it on the switch and nothing happened, cant start it...

and also i don't have warranty cause I'm not from USA

anyone got this issue? or can help me?

 

I think I read something about this in the manual. You may have reset your wireless remote codes from the car. If this is the case you need to follow the instructions in the manual on how to set your keyless remote to your car.

 

Hi,

Today I resolved the problem, just took the emergency key and plug it with the alarm and it started, but the message on the display still there, so every time need to use the emergency key with the alarm to start it...

tonight I'm gonna read the manual..

 

I know this is an old post, but I'm having the exact same problem. Did you ever fully resolve the problem by yourself or did you end up taking it to a shop and having someone else fix it?

 

So what did you do? I have the same message coming up and don't know why? Don't want to spend thousands? Is there an easy fix?

 

Either the KOS ECU lost the codes to your keys and they need to be reprogrammed or the KOS ECU is detecting a fault with the ECU or another component of the system.

Do your keys work for anything? Trunk/Doors? If so, it could be an interior antenna issue. If not, it's likely a lost programming or a KOS ECU issue.

The third page below shows the location of all of the components in case you want to check wiring:

I have a difficulty with starting my outlander 2017 as this massage appears keyless operation system service required.
