Sync car key
So, all of a sudden, one of my two keys stop working in opening and closing doors. It still can start the engine.
So far, i changed the two batteries for new ones and checked that the infrared is working (with camera phone is visible).
If i pull out and then pull in the batteries holders, i get one blink of the led and the infrared starts blinking continually, just stops if i press one of the three buttons.
Tried some of the methods for sync the key on the internet and not worked.
Someone knows how to sync a w204 2008 key?
Or maybe it is short circuit...
Can someone help?
Thanks!
