Peugeot 307 immobilizer problem

Hello guys .. I have 2002 model 307 XS.
I have been using my vehicle for 2 years without any problems, but 1 week ago my vehicle did not work on my way to work in the morning. We said it is immobilizer problem, when we looked at the service from the service I worked with, we could not solve the problem, that evening, I opened and closed my vehicle 7-8 times with a spare key, my vehicle worked.

My car did not work again in the morning after 3 days. a few hours later my friend ran it with my spare key. I have been using my vehicle with a spare key since there is a problem with my remote key. This morning I had the same problem with my backup key.

Why is this problem caused, is there anyone who has knowledge or experienced such a problem in the past?

Best regards

the flip key may be defective, the circuit inside may not be sending the signal to the immobilizer. The flip key price is around 170 lira for 307.

If there is a break from time to time, then there is no contact with the key or somewhere. After 307 battery runs out, it can forget the keys but in the case of vsvs, but all of them !! My key winding goes wrong, goes vsvs. Start the most beautiful test in any private or authorized peugeot service.

I sent the remote key to the unlocking. He said that the chip inside was damaged and soldered it, most likely it is a problem caused by him.

It is good to get out of there. I hope your problem will be there.
