Mondeo issues

[JamesH378]

Evening all, 

I have a 2008 Mondeo and am having a couple of issues with it, hopefully someone here can help me. 

1. Central locking has stopped working. I changed the battery in the key and still nothing. The car locks manually but not with the remote. 

2. Parking sensors don't work. I just get a long single tone and then nothing. 

Any ideas please?

the single long tone is the module telling you there is a fault
these systems work on a if i have 1 issue i work if i have 3 i dont work,

its actually based on a number score system so as a rough example a sensor will score 4 and a warning siren a 7 if the module gets a score of 10 or more it stops
