Oil boilers lock out for a lack of fuel, a failed photocell, or a blocked nozzle - common on rural Offaly/Letterkenny supply lines.
Top up the oil tank if low, reset the boiler once, and call an OFTEC-qualified engineer if it locks again.
Typical fix cost in Letterkenny: €80-€400. Do not attempt work on live systems - get a licensed specialist on it.

If there is risk of damage, safety hazard or no service at all, treat it as an emergency and act now. Otherwise schedule a standard visit.
Regular maintenance catches most of these early - see the maintenance checklist in the emergency guide.
