Repair Peugeot 307 key.

[airfree]

Hello matest,
I have a Peugeot 307 2.0 HDI 110 kw key with broken remote function due to washing in the laundry. The key starts the car. I bought another working used key.
So there is a transponder 1058.20 Philips (PCF7941) and another chip with abbreviation-K110 B3 on the opposite side of the pcb.
My question is:
Is it enough to replace only transponders 1058.20 to have a starting funktion and remote function on my key?
There are a pictures

change only the PCF7941 and the car should start and operate the remote control

there is only two possibilities, bad-damaged remote reciver in the car or wrong type remote.
For example the KD stuggling with this car. Learning is successfull and when you check it with diag you can see the sycro process isn't working.

@Auto Techniek - did you use the correct remote. Transponder with old and new system will start the car but fob should work after programming. Did you check FSK / ASK modulation correct so just like the one you had? Also, should better start a new topic for a new question
