Newbie - Key fob remote not working

[vandorgan]

Hi, on prising open the key fob gently, then removing the protective rubber cover, lifting out the circuit board, I noticed a small black plastic pin fall out onto the table. On closer inspection, this holds the circuit board in position inside the fob. So my board was slightly twisted inside fob, changed the battery anyway and reassembled fob, taking care to position board without pin. Tested and working, but I won't be throwing my keys onto the table anymore, as this could move board and make the connectors inside fob not touch respective switch..
