have a 10 focus 1.6 tdci.
lately 2 lights one is traction control flashes briefly and radio goes off and this morning central locking would not work and when i looked at display seemed to be reseting the date, car didn't even click when turning the key and no dash lights.
5 mins later all came back and car started.
tried spare key but will not lock or unlock
any thoughts please?
Maybe a bad connection on the battery or where the battery lead connects to the chassis.
The spare key not working is probably dead battery in key.
