2021 BMW Locking Issue: Doors Lock But Vehicle Not Secured

Symptoms

Owners of certain 2021 BMW models may observe a specific BMW locking issue when attempting to secure their vehicle using the remote control. The primary symptom is that while the doors lock, the vehicle's alarm system does not activate. Additionally, if the side mirror folding function is enabled, the mirrors will not fold in.

This condition is described by the OEM as: "WHEN LOCKING VEHICLE, DOORS ARE LOCKED BUT VEHICLE IS NOT SECURED". The verbatim owner-facing strings associated with this issue are: "The doors lock. The alarm system is not activated. The side mirrors (when the function is activated) do not fold in."

Diagnosis / Trigger Conditions

This BMW locking issue occurs specifically when locking the vehicle from the outside using the remote control. The problem is not that the doors fail to lock, but rather that the security system fails to engage fully. This suggests a communication or activation problem within the vehicle's electrical system, particularly affecting the alarm and convenience features linked to the locking mechanism.

What Owners Should Know

Although the doors appear locked, the vehicle is not fully secured because the alarm system is not activated. This could potentially leave the vehicle vulnerable. The issue involves components within the ELECTRICAL SYSTEM and LATCHES/LOCKS/LINKAGES.

Owner Action

If you experience this BMW locking issue with your 2021 BMW, it is recommended to contact your authorized BMW dealership. They can diagnose the underlying cause of the alarm system not activating and the mirrors not folding.
