The install video does a great job with the take apart and connections.
I was concerned for figuring out electrical clips, but all went well with the electrical clips.
I was concerned for tapping (splicing) into the brake switch, the pics in the video were great for this.
The video does not give much (any) advice or instruction for where to put the sensor coil or the control box.
I had put the control box inside the steering column housing, more or less where the ignition switch parts were.
I initially put the sensor coil between the radio and steering column, reaching through and using tape to secure the sencor coil.
In this space, there is not visibility to confirm a secure install.
Concern for if the tape mount comes undone and the sensor coil falls or moves inside the dash, fob will not work (out of range).
After some reflection, I told my wife to put in in valet mode until I could better secure the sensor coil.
Today,
I did the take apart to check/move sensor coil.
I found the sensor coil mount tape had become a bit loose.
So I decided for sure to move it to a location I could 100% confirm secure tape mount.
I noticed the sensor coil is just a bit larger than the 'push to start' button.
I disconnected to start button wire from the control box.
I threaded to start button wire through the sensor coil.
I mounted the sensor coil inside the steering column around the start button.
The sensor coil works great here
And I have no concern for it falling off and loose inside dash.
I had thoughts about the sensor coil being right there at the start button ignition
and being easier access for a theif than if hidden away from the system.
My thought on this moved toward...
The cyclinder/switch is gone.
Kia Boyz break into column, but no switch to be turned with USB or screwdriver.
Professional car thief will know how to actually hotwire, so hidden location of sensor coil will not affect a professional thief.
Regular Mode
Hold the fob to the sensor for a couple seconds, 2beep system unlock.
auto relocks in 30 seconds, 1beep system lock.
or hold fob to sensor for a couple seconds, 1beep system lock.
VALET / SERVICE MODE
Hold fob to sensor for couple seconds to unlock,
continue to hold fob to sensor for 5 to 10 seconds, quick 4beep unlock hold.
system auto-relock disabled. fob not required to start car.
This is VALET / SREVICE mode.
Tested and found that service mode does not stick through battery disconnect cycle.
put into service mode.
disconnect battery,
work on car,
reconnect batter,
hear 1beep system lock.
SO, Service tech will need fob and sensor coil location if battery will be disconnected.
