TechWhiz Posted March 31 Share Posted March 31 The sun had out, and as I approached the vehicle, I decided to use the old remote to lower all the windows and open the sunroof. I appreciate this function on our vintage vehicle. As is customary with the E31, there is nothing to report. Arrived at the vehicle, inserted the items, and everything is functioning, although it is not identical. Both keys were attempted, but neither functioned. Do you have any suggestions?

ForumGuru Posted March 31 Share Posted March 31 I assume the remote continues to unlock the door locks? This may be the body control module, since I believe it regulates this feature; alternatively, on a vehicle of this age, the alarm might be a result of this, similar to my E36 M3. This function may also be activated on my E36 by using the key in the lock to shut the windows and sunroof; thus, please try that. Quote Link to comment Share on other sites More sharing options...
TechWhiz Posted March 31 Author Share Posted March 31 Both keys function well, unlocking the doors and boot via the remote. However, neither mechanism opens all windows and doors when activated for a few seconds using the remote. Inserting both keys into the driver's door and maintaining them in the open position will simultaneously open all windows and the sunroof. Inserting both keys into the driver's door and maintaining them in the lock position will shut all windows and the sunroof. They seem to be ineffective when pressing the Open button on the remote key fob. Both keys exhibit the same issue, leading me to speculate if it is a reprogramming problem. The alarm is functioning properly and as intended. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted March 31 Share Posted March 31 The windows and sunroof must be re-initialized; without initialisation, they will not operate via the remote. The two front windows must completely open and shut with a brief button push; the sunroof should also fully open and close with a short touch.

TechWhiz Posted March 31 Author Share Posted March 31 Based on my recollection, it is: Sender Initialisation Mandatory, for instance, subsequent to the recent acquisition. of a crucial element. The new channel must be initialised prior to commissioning. One vehicle must have been activated via remote control. 1b If the car is not accessed via the remote control, a lock mechanism is activated, which resets after 15 minutes of the ignition being engaged. 2 Enter the vehicle and shut the driver's door. Activate the ignition keys in the steering wheel lock by briefly turning to position 1 and returning to position 0 three times (maximum duration of 5 seconds). Four Depress and maintain pressure on button 1 (refer to the image) on the transmitter. Press button 2 three times consecutively within 10 seconds, while maintaining pressure on button 1 during this duration. Release button 1 five times. The LED emits a gradual flash for a maximum duration of 10 seconds. The line that is absent is as follows: The central locking activates just when pressing one of the two buttons again. - 6 The central locking mechanism indicates the successful initialisation of the transmitter by locking and then promptly unlocking.

TechWhiz Posted March 31 Author Share Posted March 31 I have just seen your article, and it seems to be straightforward. Uncertain as to why they would become unsynchronized—presumably due to cheap batteries? Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted March 31 Share Posted March 31 That would certainly suffice. Quote Link to comment Share on other sites More sharing options...
