Those keys are to wide to fit in cover slots.

measure across slot and sideways that will be your key size.

Have you tried Large screwdriver in the slot sideways, if you could lift a little way slide something opening ( I have used my foot many times )

Get 2 Manhole keys.

Need to scratch out around as looks like it's been concreted up tight.
Chip away or run grinder down joint at edge.

Keep escalating the effort. Might need to butcher it a bit. Probably need to look at getting new one. Easy job with cheap bag of ready mixed concrete to fit new cover
