BMW X3 F25 keyless access
The question is the following. How to activate keyless (comfort) access on BMW X3 F25? CAS has been changed, all wires and antennas have been installed, the handles have been changed to touch ones. But the system doesn't work. There is one error on the antenna in the rear bumper. Can this error disable the whole keyless access system? The stock key fob works.

If you replaced CAS without CA, it will not work! All regular operations will works, except Comfort Access

You can use any antenna from side skirts or inside, or from hood where’s battery installed! Just to understand if it’s antenna issue! Maybe there’s wiring problem, maybe car had some accident before on the rear… (14-09-2022, 08:29 AM)inspi1981 Wrote: I saw lot of car with fault with rear bumper antenna, but CA on door working Each side have antennas, of course if rear is dead on side all will works fine except rear (14-09-2022, 15:43 PM)Fx82 Wrote:(14-09-2022, 07:39 AM)spider80 Wrote: I have not done anything to the car, it has already come to me like that.
