Tried to do this but my key won't lock the car while the key is in the ignition. Looks like it's signal strength as when I remove the key and hold it up it will then lock it.
Also just to rule it out I've sent our driver for a gallon of fuel just to make sure the gauge hasn't gone daft and I have run out of fuel. If I have then it's either leaking out or someone is stealing it !
Will car lock & unlock from outside using your fobs ? If yes read on . .
Had a similar issue recently with my 2.6 estate . . . could not do a door lock reset . . found out it was something to do with the door pin switches for the puddle lights. One switch was not connecting(rear o/s door ) & puddle light was not switching on . Serviced switch with a bit of switch spray & then reset worked as did the second press for deadlocking which previosly was not working

It must be to do with the switch telling something that door is open or closed maybe

but sorted my issue.
Another point . . & may be you already know this . .but do you park on an incline , hill or slope , as estates apparently are prone to not starting if parked like this . HTH
