Hello. I wanted to ask for information about the Volvo v50 key scheme. The problem is with the buttons on the remote not working. The failure was progressive. For about 2 weeks. he was getting less and less affected until now. All February corrected + of course at the beginning of the mentioned...

You write that the remote does not work and how did you check it?

First of all, the pilot tester and see what power he gives and whether at all.

I suspect it's a pilot. It seems strange to me that the car's driver once worked on this remote and sometimes not. The second pilot operates without reservation. Will he be able to download this scheme from somewhere? I will not buy the hardware to diagnose the keys . I'll do as much as I can alone.

Then buy the key and sold out the scales.

I was thinking about the option of ebbing the most. Probably the cheapest will come out around PLN 50. At these frequencies, should the RFID signal sensor indicate something, because I have one. I will check myself later on the second one. Thanks greetings. Ps. If someone had a diagram, he can share it here

How much I want to have a diagram of something that is not generally available, I take a pen, analyze and draw, there are not many five types of elements. The easiest way to work out power, then put on the forum and is for posterity.

and the switches checked? Maybe it's just a trivial matter and there is no mention of them.

Yes. The buttons are of course checked and fully functional. I will order the second key and I will break these 2 systems and let me know.

I sold the car. Unfortunately, I will not help further

Hello.
I wanted to ask for information about the Volvo v50 key scheme. The problem is with the buttons on the remote not working.
The failure was progressive. For about 2 weeks. he was getting less and less affected until now. All February corrected + of course at the beginning of the mentioned battery. Checked buttons. Mainly I would like to know what are the values of the smd capacitors on the board.
Thanks. Greetings.
