Clio 2 remote rf key lose synhronisation

[oem]

Hello. I have Clio 2 in my garage with problem of lose synchronisation between remote control and central locking module after turn ignition key on MAR.

After synchronisation procedure with CLIP, remote key working good. Lock/unlock without problems. But when i turn key on MAR(ignition) ant then off remote not work.

Where is the problem?

Hi friend
I think you have anything to interfere with the RF polled sent to the module. But check the connectors on the module central locking / alarm if it's ok, and your antenna. if ok check bataria the remote control and internal circuitry of the remote are ok.
good luck, I hope that your key is the type KRS + RF to not have problem with the immo.

The car is with immo off solution after bad starter motor repair in another garage. They burn the old ecu and uch. I remove immo and cut steadily +12v line to ecu. But i think that is not the problem. I will change battery in key and try again. Now car start ok and work ok and problem is only with central locking.

Interestingly, when i synchronize remote i can unlock the car and lock it many times. Only when i put the key in the position on IGNITION (without start the engine), then the remote stops working. This is very strange for me and i don't know why is that.

EDIT: maybe problem is in immo? When immo not recognized code from key maybe he reject remote from the memory... if is that, i must learn key to immo.

Hi,
I do not have a solution but..
I have had the same problem when trying to program used keys with various eeprom dumps. So I suspect the fault is in the dump in the bmt unit in 93c46.

A Renault XR25 programer would prob sort it but tend to be dealer only tools. Zedbull with the renault eeprom package ( special renault remote function ) will aslo sort it.

Good luck

I solved problem after disconnect and reconnect BCM :) Maybe problem is in pin contact. I only disconnect from car read dump from memory and reconnect and now remote working :)
