INFINITI G35 gear shift locked in park after alarm system installation on INFINITI G35

Some INFINITI G35 owners report experiencing issues with the gear shift getting locked in park after an alarm system installation. This problem is commonly noted among users and may require temporary measures, such as removing the panel to press the button for the shifter. A faulty park switch within the shifter assembly could be the underlying cause, necessitating a replacement of the assembly. Additionally, some owners find that the shift lever engages park without registering with the computer, resulting in a continuous beeping sound; while disabling the sounds may provide a temporary fix, the shift mechanism should ultimately be addressed. Improper reassembly after cleaning the plastic panels can also lead to the shift knob not fully returning to park, which can be resolved by ensuring correct alignment of components. In cases where the gear shift is stuck due to a discharged battery, owners can utilize the shift lock release mechanism by setting the parking brake and using a key or screwdriver to unlock the shifter.
