i changed my radio in my rover whilst doing so battery went flat got a push started then cut out nothink on the key or the fob will not activate central locking can any one tell me problem
I'd put the battery on charge for a couple of hours or however long the instructions of the charger states and then go back to it and give it a run. It sounds like the battery is totally flat. It may be past recharging - if it is you will need a new battery.
either the battery is dead (as opposed to flat) or you've mongled up the door switch on the radio. its a wire on the back of the radio (usually yellow) which turns it on when you turn the key.
