Tuesday night i left my car unlocked as i had planned to doing something on it but lost motivation after dinner, next morning jumped in to take kids to school and on turning the key there was not even a click from the starter.
Battery is fine and all other electronics were working fine, got out and tried to lock/unlock with fob but nothing happened and no lights.
Ran inside to get spare key/fob as my car was blocking wifes car which was blocking the bike .
Fob didnt work either so i just locked car again with key and waited about 20 secs then unlocked and it was all good.
In my lunch break i got the fob checked and battery was as good as new ( i have never replaced it in 8 years ) and it was transmitting as it was tested.

Only conclusion i can come to is that possibly it immobilized itself or there was interference with the fob ?
Been fine the last 2 days , not sure if its related to my spider or lack of problems.
