I had to put the key to the steering column to start the car every time. Removed the rear cam and all is fine.
I ran my wires from the dash cam on front, underneath trim and headliner on the passenger side.

Thanks Mike-Man... it may have been one of your posts that alerted me to the possibility of this interference...
Did you happen to try to re-route the cable along the drivers side, or down across the bottom at all? Or did you only try the one route along the passenger side at the headliner?
and
How close to the top of the glass did you mount your camera?
Do we know where the antenna is located on the F25 to pick up the Fob signal? Maybe it's just a matter of avoiding that area with the power cable? |
Mine is routed the same way... power runs from the rear fuse box, up the C pillar to the headliner, then down the passenger side headliner to the windshield. Rear cam power/video wire runs the same path to the C pillar then continues on.
Mine is a Blackvue DR650.
Are you wiring it in properly or plugging it into the center 12v outlet? See SIB below.

Check Control message "Remote key not in vehicle"
All series with the Comfort Access optional equipment
Subject matter
The Check Control message "Remote key not in vehicle" is output even though the remote key is inside the passenger compartment.
Action
There is no fault in the Comfort Access system. Replacement of the ID transmitter does not achieve the objective.
Technical system limitations may mean that the vehicle fails to identify the ID transmitter (remote key) under certain preconditions. Reasons for this include:
- Coverage of the ID transmitter by metallic objects.
- Frequency interference due to smartphones, mobile phones, MP3 playback devices (e.g. storing smartphones and ID transmitters together in the cup holder) which may cause interference to the transmission frequency of the ID transmitter.
- Charger in vehicle electrical system power socket
- Storing the ID transmitter in front of the instrument cluster or the display (switching frequency of the display illumination may interfere with the transmission frequency of the ID transmitter).
- Interference from pylons.
The receiver for the remote is between the roof and headliner. Not sure where though but the wiring might be run close to the receiver causing the issue.
Description of the receiver:
Remote control receiver
The radio signals from the remote key or the ID transmitter are received by the remote control receiver and relayed to the Car Access System (CAS) or the front electronic module (FEM) or the Body Domain Controller (BDC).
Depending on the series, the following control units control access to the vehicle (central locking system) and its systems (e.g. key identification, electronic immobiliser, release for engine start):
Example F01, F12: Car Access System (CAS)
Example F20, F30: Front Electronic Module (FEM)
Example F15, F56, I12: Body Domain Controller (BDC)
The control unit (CAS or FEM or BDC) is the master control unit. It is therefore the control unit (CAS or FEM or BDC) that issues the release.
The remote control receiver has a transmitter/receiver module. This enables bidirectional communication to be established between remote key and/or ID transmitter and remote control receiver.
The remote key is the key for the central locking system. The ID transmitter is the key for the central locking system on vehicles with Comfort Access. If the vehicle is equipped with Comfort Access, the vehicle can be unlocked or locked without active use of the ID transmitter.
Functional description
Pressing the release button or the central locking button on the ID transmitter transmits an encrypted remote control signal. The remote control receiver receives the remote control signal with an integrated aerial. The signal is then demodulated, processed and checked in the remote control receiver. That means: The radio signal contains a vehicle-specific constant 'value' which is checked by the remote control receiver. Only when this constant value is correct is the information forwarded along the local interconnect network bus to the control unit (CAS or FEM or BDC). This means: Radio signals from remote keys or ID transmitters belonging to different vehicles (but the same product line) have no effect on the access to the vehicle or its systems. The remote control signal is authenticated in the control unit (CAS or FEM or BDC). If the request is duly authorised, the control unit (CAS or FEM or BDC) wakes up the vehicle and either locks or unlocks the vehicle.
The transmission frequency of the remote key and/or ID transmitter is country-dependent. The following high frequencies are currently used:
315 MHz
434 MHz
868 MHz
