Hi,
I have a smart roadster Coupe 2004 only ever had one key and now I am having issues. It started with the key having a very weak signal, i had to be very close to the car for it to lock/unlock so i though it was the battery in the fob. I changed the battery in the fob but this made no difference.
Now the fob does not work at all, no 9 flashing lights on the indicators or anything. Press any button, lock/unlock/boot no response at all. If i disconnect the car battery (which is new and tested so not the issues) and re-connect after 10-15 mins the fob works fine. But if i park up, leave the car for 30 mins the key is dead again. So i have to repeat disconnecting the battery to make it work again.
Has the key gone out of sync and need re-syncing, but why would the key work after disconnecting the battery?
Any help would be great as my wife is really keen on me getting rid of the car and this could be the last nail in the coffin
