The keyless go on my car seems to be acting strangely. I just want to confirm if this is nornal.

When you unlock the car but do not start the car, and you try to lock it again, it will only do so by activating the button on the keyfob. And if you sit in the car for a certain amount of time after you kill the engine, it will not lock other than using the keyfob.

Are these normal behaviour for the keyless go? Seems annoying...

 

Thats not normal at all. It should lock no matter when you push the button on the door handle, as long as the engine and ignitions off, and the keys not inside. Have it checked out by your dealer.

 

Having the same problem. Did you find the solution?

 

There's a button you press in front of the door handle. Place your finger on it and it will lock/unlock, sometimes by touching the door handle it will lock/unlock.

 

Yes, that was working. But I was playing with the range by lock/unlocking it. Now it is not working. I will check the battery. Is the battery under warranty?

 

Yes. Bring it to any dealer and they'll take care of you. Of all the places, Downtown Benz at Dundas seems to always treat me well.
