Key detected in car

Kmurphy · 02-16-2018, 06:33 AM

This is an odd fault. I have a spare key for my F32. My normal key works fine with central locking and starting the car.

My spare is detected in the car in any location and I can start and drive, but it will not remotely unlock or lock the car. I have tried getting close, near back window, but nothing.

Anyone else had a similar fault before I embark on spending £100's at my BMW dealer for a new key.

Many thanks.

Try a new battery in the FOB first..see if that corrects the issue. If not, try re-initializing the FOB. Hold it to the right side of the steering column, while simultaneously holding your foot on the brake and pushing the START button.

Get out and see if the car locks.

Many thanks for the response. Yes tried the battery swap over and a new battery and also the initialisation with foot on the brake and start. I can also see the fob is recognised in the menu.

When you try to lock the car with the spare, are you sure the primary key fob is not inside the car?

Yes - I leave the primary well away. I think it must be a fault in the key with the antenna for remote operation, so that probably means a new key.

Appreciate the response.

If the key doesn't work that would be a defect in materials or workmanship and should be a warranty item, so long as there's no visible damage from external forces.
