Renault megane 1 how to programming remote?

[Panathaole]

Hi

I have a renault megane 1, in car replaced the uhc and immo off the ecu, car starts and no fault codes available

Key is with IR...

But I can't programming the remote to lock the car, i try by holding the central locking, not working,. I hold the lock button on key and try programming by pressing three times after, nothing happens....

How i can programming the remote?

the best will be to use aftermarket central module with remotes

Thanks but i want to programming the cars keys if is possible...

You must have the immobilizer 4 digit pin code to program the remote

[Catalizator]

press the lock button on the console, then press on the key and wait until the LED on the key goes out

no code needed. the synchronization of the IR receiver is done as described ...

[drz]

Sync is NOT adding new key. To make new key work is not so easy. You can sync only existing keys, not new one.

I don't want new keys, i have the car keys to programming in "new" uch, i had make the ecu already immo off, i need only the remote.....


Edit: The keys work fine (the remote part) in old faulty uch, if it is so hard to synchronise the remote part of the keys then i read the mcu and make clone the processor eeprom, that should work i guess...

[Supas]

If I clone the new uch with the previous one, you have to, with the emergency code and the centralized key, place the code and enter programming ... but if the uch is completely new, I think that the information on the keys you have no longer they are more

[Supas]

Another interesting piece of information is that these IR controls have a 16-byte data on their micro which are evolving at each push of the button. After a number of keystrokes it stops working .. the way to restore it or to be able to use a remote control from another vehicle is with the code sXXXX and carprog or bchip to generate a new 16-byte file for the micro and save it ... revive the controls that are from the car or you can program a used key from another car

I had Megane 1 1996 with 2 keys out of synhro and the owner drived the car inputing every time the code from central lock button manually

To resinc must enter the code manually after that press the lock button on the dash and hold 5 seconds and central lock must cycle then press the button on the key near the receiver on the ceiling and central locking must cycle, press the button on the second key if you have central locking must cycle again to confirm

switch ignition on off and check the remotes

The only issue i have now with the car is the remote.....

the ecu is immo off, i replace the uch(the original is faulty) and i want to reprogram the car keys (only the remote part...) with "new" uch......

So if i understand correctly, i extract the pin from the key with carprog, with the key pin is possible to programming the cars key to "new" uch? ONLY the remotes i don't care for the immobilizer....

Write dump from ori uch to new, resync key and it will work.

any pin out to read the uch? S103600301 A otherwise i exchange the mcu's....(it is sensitive in heat???)

hello
you may have a label in the remote control with a code, with the trantir software you can find the pin code
