Hello,

sometimes I see a blinking red led in the top right of the key (keyss system), sometimes not.

I tried to find some explanations but failed.

Can someone explain me what the led means and when and why it starts to blink?

 

Thank you.

Thank you very much @inspectorman and sorry but on my manual was not explained.

I need to change the battery for sure.

Mine flashes red when close to the car, pretty sure it's normal as the key and car can see each other.

I've always assumed it to be normal as mine has done this from new. The LED flashes when the key is in close proximity to the car, it will stop flashing as you move further away.

In the early days of keyless entry systems, thieves could recover a signal from the key fob stored within a house and use that to open a vehicle parked outside the house.
 

This new style key fob has a motion sensor within it. If it has not been moved for a period of time it "turns itself off" and will not unlock the car.
 

You can try this feature out as well if you park your car in a garage at your house. Leave the key fob sitting on the roof or hood, go away for a while, then try opening a door using the door handle. The car will stay locked until you pick up the key fob and shake it a bit.

 

When you move one of the keys and if they’re within range of the car they’ll all blink as they sync their encryption codes with the car.

 

This added level of security also contributes to the increased battery usage.

Reread the text in the image….. It says the battery is low if the red light DOES NOT flash. 👍🏼😉
