Not scooby I know but I'm sure it applies as well, we have a 2011 land rover and a 2011 Transit, 2 days ago at home both could only be locked/unlocked by using the remote next to the drivers door. Drive a few miles down the road and both can be operated from 20 ft away, both have the ford engine so I'm sure something is interfering and the spare keys are the same, any ideas ????

Do you live near a radio mast or petrol station?

 

shop automatic front door sensors can do this also
I have had the same happen for no apparent reason
Move the car 10 feet and it works

 

i had this problem with my old bugeye when i parked it in car park near police station i wasnt able to disaram the the car and had to be towed 100 ft down the road so i didnt get interferance from the police mass

 

Happens to me in my Classic. For me its the RF interference from close by radio / mobile phone masts. In the older cars it happens because the government released a band of frequencies for mass use, which happened to over lap Impreza alarm and IM signal. No supprise when it doesnt work when its 0.5 watts vs 20,000.

As soon as you move the car away from the 'line of site' it works fine.
