Loud beep and reset

[Herison]

Hi!

I've got a Peugeot 207 (2010) hatchback. It is wierd and annoying a bit, 'cause when I turn the ignition off I hear a loud and long beep and then I can lock or unlock the car with the remote, but after a few minutes not. It looks like something has reset because I lose my clock settings, but the radio stations and the bluetooth pairing remain.

The fuse in the glovebox at the costumer position.
My key has been programmed recently.

Sorry for the dodgy explaination.
I hope someone knows the solution.

Thanks in advance,
Peter!

It sounds like a permanent supply feed is missing somewhere. Check carefully all of the relevant fuses. Has the radio been changed?

No, it has the original radio. I thought about checking the fuses.
