How to remove broken door latch

We had someone try to break into our 5th wheel and they ruined the deadbolt keyhole. We cannot unlock the deadbolt.

Any suggestions on how to go about removing the entire latch? It has 2 keyholes, one for the deadbolt and one for the latch pull itself.

Once removed, we plan to replace it with a combination style latch.

I've tried to search the forum, but didn't find much on the subject. Thank you in advance for your help!
