Megane SCENIC 1 button RF remote issue

[zyjekrc51]

Hi!

Had got customer with non starting car.
MEGANE SCENIC gen 1 PH2
engine 1.9 DTI
ecu bOSH MSA 15
UCH SIEMENS eith motorola HC705

Remote key is 1 button RF with separate transponder 4D64

when car came to me - Remote worked ok but car won't start -immo light on dash was blinking fast.

I have made a new transponder and programmed it to car - then BANG!!! -car works!!! but remote stopped :-(

I heard that transponder(separate) is matched with remote so when I have used another(new) transponder with already used and programmed remote - there is no sync between transponder and remote anymore.

I have tried to resync remote with button but no success - using status data on renault CLIP I can see that UCH(siemens) senses RF signal but not allow to sync the remote.

DO YOU KNOW HOW to solve that problem - special preparing procedure for transponder before programming or renew procedure for remote? or ....only new remote from dealer with paired transponder ? please let me know if You found or heard about solution for this issue.

thx in advance!!!!!

hi!
I was trying to do that but car won't register it - I tried a few times with no success, have You got idea WTF ?
I read UCH MCU and seems that orginal thata matched orginal transponder but car don't "like" this transponder
DoYou know what the difference is between CLIP's 2 options in IMMOBILISER CONFIGURATION MENU? there is IMMOBILISER mode 1 and immobiliser mode 2 - what can happened if I will use mode 1 (I thing there is mode 2 stored in UCH)

Hi,
what Kuzmanov said.

Put everything as you found it, change immobiliser type ( so if its type1 change it to type 2 and visa versa)
common problem
