Peas should be fine after 2 years and ok but not great after 4. However it does depend a bit on the conditions they have been kept in - if they have got damp at any stage they will not germinate. Seeds kept in plastic bags can sweat and this can lead to very poor germination. It may also depend on the variety, I'm not sure.
This spring I sowed Douce Provence peas from a packet which said packed 2016 sow by 2018. I last sowed some from this packet in 2018 when they were fine. Not a single pea germinated this year, they simply rotted.
