Hello together, I bought a SL 500 R129 on the first day when I wanted to register it, I did not get the car with the infrared remote controls any more. It didn’t want to flash green or open and if you unlock the door with the key is the immobilizer inside and the alarm goes off at the start. I thought it was due to the batteries but these were exchanged and after 2-3 hours it worked again. It happens every 1-2 weeks that it nic ht works and after that you can open or close normally again. Both keys don’t work – so it can’t be because of it. Did someone have this problem before or knows what it might be? Thanks Pat
