Just lock the car fob and then tap the sensor on the door immediately, you will hear another click which will deactivate keyless entry, just be sure to wait 10 seconds or so to confirm all is locked, mine sometimes isn't, after that the car won't open without the fob being pressed.
Can I just check I am doing this correctly, as my 7.5 GTD does NOT work in this way ...
I have locked the door with the key fob
Immediately after locked, , I touch the sensor on the door handle - you then hear another click
If I leave the car for minimum 5 minutes, and come back, I can STILL unlock the door by just touching the door handle. Keyless still seems to be working.
Am I doing something wrong ??
(I've tried it several times, and this "keyless deactivation" never works ...)
