Peugeot 407 - Remote control in the key (3 buttons) - no resistor

Question

Hello.
I got just such a remote control (3 buttons) to replace the microswitches. For "ease" the owner himself desoldered the used ones. The problem is that he also collected one smd resistor, whose value is difficult to determine. Request: could someone with such a remote control or access give his (resistor) value?

This is TDK5100-ASK / FSK Transmitter 868 / 433MHz. Does your friend have access to the internet? Potential sites: olx.pl; sprzedajemy.pl; gumtree.pl; allegro; ebay.pl etc. My colleague did not understand me. I wrote that you can either wait (as time is) or look for people who deal with similar topics and talk to them in private. The above information should help, especially the clippings from the datasheet which is worth downloading the whole. Good luck

Hello I suggest : 1. Download the IC layout datasheet next to it and analyze the layout and application that the manufacturer can draw. 2. Access to the same remote control that they may have in some remote trading shop, bazaar, olx, allegro etc. 3. The third method is a friendly colleague from the forum who has access to this pilot and is reading the topic or colleague @LXT he will search the electrode forum for people who do this.

ad.1 The system has the marking 5100 datasheet probably not available or at least not public. ad.2 I currently live in a country where there are no pilot stores and the bazaars sell a completely different range. ad.3 I set up the topic just to get such help from any of the colleagues on the forum who deals with it or is in possession of such a pilot (his or his client) and will be so nice that he will read the value of the unfortunate resistor .

TDK5100, it's actually ON. And my strap is R3, so is it for ASK or FSK 15k. I soldered there for the purpose of trying out 10k and interestingly it works only has a small range. Well, maybe he finished the new battery. Next week, the guy is coming up again, we'll replace the resistor, battery and see. And of course, thank you very much for your interest in the subject, time and specific help.

For me, the meter showed 5 ohm (I bet more on the coil) - of course soldered into the board ...

LXT · Answer

Can you read what is written on it? If something is obviously there.

wqq · Answer

Element without markings ... I don't have an inductance meter, so I won't help either ...

antek1cza · Answer

I suggest placing a sharp and clear picture of this part and the 5100 chip that is next to it.

wqq · Answer

I will not do sharper ...

That's right: In the diagram with IC 5100 and IC 5110 Practically the same but the chips themselves have slightly different parameters and the boards differ: 5100 5110 where is it written because it has too high resistance and there must be a choke with a resistance of approx. 5?!
