Keyless Entry issues

[NDR008]

Just an update on my case!!
Took my car to the dealership 4 days ago.! And told them that my issue should be caused by the oscillators that are not well positioned.. they said they were going to tell the technician about it..

they did their diagnostics of course before trying to do what I told them at first, but ended up checking the oscillators and in fact that was the problem!

one of them was hanging off their actual position, so they reposition the oscillator and put it back in place and now the keyless entry is working ss it should

I read that somewhere else too - was yours the one in the centre console?

I read that one too! But no mine was in the back one

That is the one i checked myself and also the dealer replaced.

One of us doesn't know what "oscillator" means. I think it's you?

Do you mean antenna?

There is a crystal oscillator in the receiver. I think you're both "wrong." The receiver was likely replaced, which contains on oscillator.

Well that's how they call it and that's why I called it like that lol I have no idea how the device works, but yes basically is an antenna

Sure, but the position of the oscillator isn't the problem. The part in question does have an oscillator. It also has a connector, for example, but you wouldn't say the position of the connector was the problem.

As someone that works at a top 3 automotive supplier (not BOSCH, but the Japanese one) all I can say is... People refer to the same thing in different ways (often incorrectly) but so long as we understand each other who cares?

I'm still hoping this thread helps me figure out what to do.

Any updates on the resolution?

Yeah the dealer followed the manual:
Swapped rear antenna which was reported as faulty. Nada.
Swapped body ECU. Nada.
Took apart interior and swapped antenna. Nada.
While re-assembling the car a technician noticed the wire of the connector to the antenna in the rear was loose. He recrimped and voila. Works!!!

It works every time for the last 8 months. As new it never worked this reliably. Clearly crap quality control at the production site.
