Ford fiesta keyless ignition not working

[Kyle1999]

Hello. I have a Ford fiesta 2012 1.6tdci with keyless ignition, recently the fob won't unlock or start the car, I have to hold the fob near the ignition till the steering lock comes off to start it.

I have the fault codes and tried googling them but have had no luck with any fixes, I replaced a part which was suggested on one of the fixes I found but still not fixed. 

I'm currently in the process of buying a house so can't really afford taking the car to Ford just yet not till I know I can't personally fix it.

These are the fault codes I am getting: 

B10D9-87 PATS Transponder

U201F-13 external receiver

I have changed "ANTENNA CONTROL MODULE UNIT" part no: 8a6t-15k603-aac. Which is located by the hand brake. I have also put new batteries in both my key fobs. 

Any help would be massively appreciated! Thank you

Just curious, did you ever get this fixed?

Poor Kyle hasn't even visited the site for over a year, so obviously busy with his new house, and the assumption that yes he did get it fixed, otherwise he' s been waiting outside in the rain for a year desperately trying to get his car to work!

If you have a similar fault, you'd be better off starting your own thread rather than waiting for a one post dormant guy to respond...
