Clio Mk3 Key Fob

You could try here, I have found them very helpful:

Autodata:

'Key/remote control can only be programmed using diagnostic equipment'.

Thanks Davey, will give it a try.

Thanks Chris, this is my concern to be honest. The sad thing is that it's the same key and fob and was removed from it's battery for only 5 minutes whilst I soldered on the new microswitch :(

Cheers, Mark

I've changed micro switches before with no problems. Take the switch back off and see what happens.

Can't see how fixing a micro switch should have "de-syched" the fob.

I presume that the passive side of things is still okay? Can you start the engine? If it's just door unlocking I'd be looking for a poor connection somewhere.

Thanks Graham, I'll do that and see.

Many thanks, Mark

Thanks Tim,

I was wondering if the fob being disconnected from the battery for an extended period may have de-synched it.

The car does start at least, but being a version with no driver's key lock, she has to play as gymnast to get out and lock the car securely.

I'll remove the microswitch in case I have shorted across it maybe - not sure how I would have, but SUI (soldering under the influence) may not have been my smartest move :)

Cheers, Mark

Still no joy I'm afraid. I have another key fob from another Clio mk3, is it a matter of just replacing the chips or does something else operate the immobilizer?

Cheers, Mark

usually key fob transponders are passive devices like a short coil of wire
