Local auto locksmith says cant fix it as cant get barrel, Have ordered a replacement key cut to code to see if its a worn key. failing that mobile mechanic ?? -. Can ignition lock assemblies be got from motor factors? . suggestions please? Honda 2005 crv automatic..

Do you have a spare key? (I guess not). Does the key actually turn?
If the key turns in the ignition but nothing happens, it could be an immobiliser problem.
If the key won't turn in the door, it could be due to lack of use and perhaps lubricating the door lock might help.
If the key won't turn in either of them, then it's the key at least. And that's just the physical part. They have electronics.
Is the battery in a good state of charge.
Does your insurance cover you for locks? This could be on your car insurance or on a breakdown cover policy.
Re-mapping of keys to locks and ECU's can be expensive..

Being an automatic, I guess you remembered to put it in P or N (and had the brake pedal depressed as some cars do).

Put your VIN in the Honda recall checker, there have been more than one recall for Honda ignition switches.
