Immobiliser fault code 13 on 2 .4 duratorq (2004 )

[Dave Deeda]

Hi, I know this topic comes up loads, and I have trawled pages and pages of really helpful stuff that has got me to this point, helped me understand loads, but I could really do with some last details if someone could spare a minute.
So..2004 duratorq 2.4...won't start, have sussed out the flash codes and it says code 13. From a chart I have found, this relates to keys not being read.
I have two keys with chips, have been fine for years. Now not working. Also keys not together, understand that bit.
Last week, went to start, turned over, but needed second turn, but dead.spent day checking things, then for no apparent reason, suddenly started. Fine for a day then won't start and same for days.
Have checked loads of connections, nothing obvious.
Q is...although it reads 13 as key, could this be an transponder issue ? I've checked it visually, but is there a way to check it with a voltmeter? If the transponder has gone, what's the best route forward ?
As another confusing clue, occasionally go to start, and immobiliser light goes out, but won't start, nothing, lights on dash go out and a click from Relay (?) under passenger dash.then oil light goes on for a few seconds, then goes out before immobilser flashes normally... but then usually does the whole flash code13 process again.
Many thanks
Dave...soon to go bald not from hair loss, but from pulling it out..

The fault could possibly be in the reader which wraps around the barrel to read the key chip.

It could just be out of place or have a damaged wire

You might need to pull the "actual" fault codes using forscan or IDS, this will give a good idea of where to look...."From the chart I have found, relates to keys not being read" is a bit vague.

Ok thanks,sounds like I might have to get a mobile electrician in to do that, it's going out of my depth a bit.
I got the info about the codes from a previous post about immobiliser issues, I'll try and upload it here..do I take it this is only a rough guide, ie the fact that it's doing a flash code 13 might be something else entirely ?
Cheers
Dave

Thanks, there's nothing visibly obvious

Forscan will be quite specific rather than pointing in the general direction...

You can set yourself up with Forscan for less than 20quid.

Have had a mobile electrician out and is sorted...
Multiple hoorahs....
After pulling out half my electrics I said...' but the code says it's to do with the transponder ring..' he then placed my original key (with a chip) inside the actual plastic ring ( taken off the ignition barrel ) and it fired up....

So it seems like the transponder ring is breaking down...Will only read the key when it is not next to it, but inside it.
I imagine might pack up altogether soon...
One more question..am I right in thinking that if I get a new transponder ring and attach it to the wiring, it should work properly ?
Ie, the transponder ring does not have to be coded to the immobilser and key, it just reads the key ?
Thanks

Straight forward swap, no coding required

Great thanks..then any ideas how to source one, ie Ford dealers ? Because its a Ford part in an Ldv, its difficult to search...in terms of a Transit, would this be a mark 6 ?
It's a 2004 2.4 duratorq ,not sure what he.
Thanks

This listing has ended, but the part numbers may be of use to you, if it looks the same as yours

Mk6 would have been current in 2004, but are there no numbers on the one you have

There's a guy on the 'Club LDV' facebook page who sells genuine parts
