I bought a 2nd hand 1995 BMW 318I in South Africa. Good condition. No owner’s manual. Everything worked ok for a few months. Then the batteries of the remote key transmitter (3 button) for the central locking was getting flat and it starts to open and close intermittently. When the car was lock with the window open the remote could not unlock the car. I opened the door trough the window and the alarm went off and the red light in front of the gear lever starts flashing. I could not stop the alarm with the remote (probably flat batteries) and without the proper procedure how to disarm it I disconnect the battery of the car. After reconnecting the battery and changing key transmitter batteries (voltage ok) and making sure the remotes are transmitting (Led flashing) the central locking does not work.
1. What is the procedure to reset the central locking system of my mistake?
2. What is the procedure to synchronize the remote with the car system if the remote batteries are flat of the spare key?
3. How can I test if a remote is transmitting?
