Hi everyone, unfortunately my cars key fell of my hand on the floor today. After that none of the buttons are working neither the light in the fob and IR light blinks no matter what I do. I opened the door with that manual key and the key could start the engine which is a big relief. What should I do? What could be the possible reasons for fob going dead? Thank you

Hello and welcome

Could be a broken connection on the board in the key. I’d take it apart (as if you’re going to change the battery then carefully slide out the circuit board and look for damage.

Thank you. I’ll check that and see if I see any broken connection of the board.!

I think you have dislodged the transmitter coil.

Good call for the RF side, the IR would still work though
