BMW 650i Cas4, 868 mhz - bobdinro - 23-08-2022
Hi guys, I have in my workshop A 2012 f13 650i long time now, cannot resolve an issue. Car start only with key touch to coil, no keyless function or remote. Check everything, door handle, keyless antennas from car. Remote signal is ok, no fault codes in CAS or FRM. Another key programmed and still no keyless or remote functions.
Someone any ideas?
Thanks ! Have all a nice evening!

original key? Because aftermarket keys doing this quite often. They are just bad. If its not an original key, make another one and try to buy quality one. Never seen a original key acting like this, unless battery was dead in the key.

Key looks original, customer say it's original, tested with frequency tester remote and have signal battery new. Programmed aftermarket one (maybe low quality MK3) new and same no keyless and remote function.
If I remove one by one keyless antennas, CAS module give me fault on every one.
I reprogrammed and coded CAS etc...
