Renault megane 1 how to programming remote?

[Supas]

I don't remember which capsule brings the micro ... but I would change the micro directly if it is not possible to read the incircuit the uch ... in case of desoldering it uses flux and hot air only to the legs ... never to the core of the micro

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

if you see above i have the pin code from the key, BUT i have other uch.... is pin code from key enough to programming remote in donor uch?

[drz]

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

Yes, you can swap mcu. But I agree with Rafal, the best solution is to install an aftermarket remote - you will have 2 keyfobs, instead of old ir ori which can stop working very soon, or receiver can die ....

yes, i understand that for aftermarket remote, but car came with two working keys.........

if your uch is new l think you can

It is used one that is working right, i don't make it virgin because i have only renolink 1.87(ori)
And it doesn't support that old car....

[eric paris]

document from dialogys
in the pdf you can select the text and translate it into your language it's easier

Ok so much missinformation here.
Pin code sync procedure will work only if your keys came with replacement (as you call it NEW) uch.
If not, as someone said before, you can try to swap MCU from OLD unit to replacement (NEW) and then try pin code sync procedure.
Your other option is to PROGRAM old keys to "NEW" uch. You can do it by using carprog, link for all info here - https://www.car-auto-repair.com/carp...megane-scenic/

yes it is correct...................and it reason as i wrote before why the best will be mount aftermarket module with remotes
but................if user want to play few houres with old crap car - no problem

Agree, most users that posted on this thread are confused and are not aware that SYNC procedure is not procedure that can add new (used) key to the uch that is not matched to

Hello you need to virginise uch and then you can add used remote if your ecu is in immo off state no problem
if you have Renault ecu tool it’s easy by obd

Swap MCU or clone MCU is your only/best chance, and you can reactivate immo to on...

Hi again, i manage to find a remote from the "new" uch, the remote works fine, i extract the code and make a second key from the old bsi with carprog...

Immo in dash disappear now,

I put the second key i enter the code, i push the central lock button and i push key button too, i hear the locks once but remote is still unprogrammed, i don't have immo light on dash, and i cant programming the second remote with everything combination i found
....
