i have seen one of my friend that can renew some PSA remotes from china without desoldering the NXP and even without opening the key shell, he presses the lock and the unlock buttons of the remote (i dont know how many times and the exact timing) this was taught to him buy a chinese that works in a factory where they clone car remotes. If it's a PSA remote for Peugeot 308 407 508 ... it can renew it after it has been programmed to a car. I asked him how to do it but he kept refusing, and i have many second hand remotes. With OEM i can renew them using some tools but with chinese remotes i can not.

Here we talk about older non-flip 2 button remotes with external transponder and this thread has nothing to do with these you mentioned.

Thumbs up mate but Instead of all the stress, just virgin d bsi and it will accept used remotes. I do that daily.

With your "virgin d bsi" can I let a xsara picasso BSI work with 206 remote key? Thanks.

Is there somebody still alive in this thread?

I have a confuse about the theory: Some people around me replaced their chipset of the remote board(motorola 70576228), and the key keep working. my confuse is , where the remote ID is stored? Or another probability is the remote ID is only unique for each remote model ?

The remote's ID is in the MCU of remote (motorola 70576228) and the eeprom of BSI also.

Thanks for reply.
I mean I know people around me their remote become broken then they replaced the motorola chipset then can work continue.


If the remote ID is stored inside the motorola chip , why they can continue use the remote after replace the chip?

I think that they replaced the transponder chip only. Motorola mcu has a sw (flash dump). Are they have this dump? Can they read/write this mcu? The ID is different for all remote.

I sure they replaced the motorola chipset 75076228. Because I also purchased one 75078226 for backup but I didn't use it, for the key of my Picasso never broken, and I found my chipset is different , my one is 75078020 , at last I re-sold the chipset to other guy and he told me the fix is successful.

How could they to learn the remote to car?

Seems need to follow a sync process. Like something Push a button for ten more seconds.

It is impossible. The PCF7936 include the remote ID. If the PCF7936 and Motorola MCU include different ID then can not to sync the remote to car.

O, disclose the mystery. I just checked with the guy, he told me if the car was manufactured after 2005 include 206/207/307/C2/Picasso／........ by PSA for China market, then replace chipset , or swap remote boards, just need a simple resync or re-pair by scan tool.

Wait. Do I understand you well?
1. He bought a new Motorola mcu.
2. He soldered the new mcu into the used remote what included an old (used/locked) PCF7936 transponder.
3. He resyncronized the remote to an other car with a universal scan tool.
