I'm new to Mercedes and Keyless go, my new GLC AMG Line Coupe has keyless go and I've found that when hosing my car down with the keys in my pocket the doors keep unlocking and locking. Obviously the finger sensor senses the water and unlocks the door. This is very alarming, could this happen when it's raining if I walk past the car with the keys in my pocket leaving the car unlocked. I've had 40 years of working on commissioning and calibrating Electrical equipment and find it unbelievable that the keyless go system can't be set up to only sense a finger and not water. Has anybody else experienced this.
