It sounds like an odd one. If they were able to program a key then you would think there was good communication with the ECU & security module.
What are you using to try to connect to it / diagnose it. Only lexia 3 with Peugeot Planet will connect to a.306 of that age. If you are using PP then sounds like there's an intermittent connection issue. I'd check the condition of all the main connector plugs (ECU, dual relay behind ECU). Spray with electrical connector cleaner / lubricator & reinstall. Can't do any harm. Also worth checking for poor earth's.
No apark could also be a knackered.crank sensor so worth checking signal from it (if you have the means) or change it out. They're relatively inexpensive.
It's almost impossible to diagnose a car remotely. If the above doesn't sort it I'd suggest you sign up to an Autodata trial. It's only £10 for the first month. (Make sure you contact them before the trial expires, otherwise you'll be tied in to a pretty expensive annual subscription). During the trial you can download lots of wiring diagrams & diagnostic info for testing pinouts on ECU plugs etc. It'll give you at least a chance of chasing the issue down, providing you've got the skills/knowledge.
Good luck!
