Toyota remote central locking activation

[WarChild007]

Hi,

I have a 2005 Toyota corolla verso
It appears that by pressing the lock button on the key fob I've deactivated the remote locking fob. The light flashes on the fob buy neither fob locks or unlocks the doors.

It's not keyless entry it's just the central locking fob. The locking works fine via the in car switch but it's like the car can't sense the fob any more.

It was locked but I checked to see if it was by pressing the lock button again. How can I get it working again?

I needed to resync the fob to the car, a series of opening and closing the door with key in and out of the ignition.
