Megane II Keycard repair instructions / Development

[mervetheswerve]

Great post. repaired a key that would not work (insert key instruction would not go out) on customers car that was stranded. they have now got a new one and are using the old that was repaired for emergency purposes. The job is fiddley and time consuming as you have to take care not to do any more damage but worth the effort.

Hi I'm new here and I joined specifically to say Thanks a million!!! for putting up this post. I had this problem and after finding your page was delighted. My fella followed your instructions and now the card is working perfect. Wish there were more people like you. Again thanks a million.

HI All

Great post, pity I tried to do this myself without reading this forum first. My problem is as described by others, the car opens but asks me to insert card when I have put the key in.

So I opened it up, one of the legs on the transmitter was loose and so I soldered that on. Key still doesnt work. I think i may have damaged the coil in the process.
When measuring the voltage across the components around the coil and the coil itself i dont get any reading, but not sure if there should be?

Found a break in the copper wire on the coil so unwrapped it to the point that the break was at, got about 30 cm copper wire off which is worrying.
Going to solder the coil back together (copper to arm) and then back onto the board and see what happens.

Any advice?

My keycard worked just fine but suddenly stopped to open/Close doors. Manual key will only Lock the actual door With key aswell, not all doors. Car says keycard not detected when outside holder but when inserted the car starts

Will I have to open card and do soledring fix or might there be som Electronic "reset" to try prior to work on the hardware

The fault seems to be Connected to some battery problems a bit earliere.

I have to say that I must be the only Megane owner who hasn't had a problem with the keycard. In fact, we were on holiday in Northumberland last year and my mother in law accidentally washed both my keycard and bank cards on a full machine cycle. I was expecting a lift home to pick up the spare, but it is still working over a year later and so are my bank cards! A warning to those who don't check pockets before putting clothes in the wash.....CHECK THEM FIRST PLEASE!!
