Urban resources are often inside things. Once opened they often need to be re-closed to extend the useful life of the contents. This might be problematic in the aftermath of flood, fire, earthquake, or other events, and in any event you want to be prepared to be more self-reliant.

[This is, of course, another cut at things discussed in part in other threads but I hope a discussion looking at things a different way would be useful in considering and reviewing your kit.]

What should be in your well-prepared collection of legal, manually operated openers and closers? Which are candidates for a bug-out-bag or car kit?

Openers
Can opener
Church-key?
"Stuck" jar lid openers
Wine / beverage bottle openers
"Stuck" interior doors and drawers
An opener for your padlocks without the keys / combination
A few sizes of pry bars
A few sizes of chain cutters
A few sizes of scissors / shears

What other container / enclosers do you commonly encounter?

An opener / ignition starter for your car without the keys / combination?

Is there need for a "gamma" / plastic bucket opening tool?

What tool do you use to open tough plastic clamshell packages?

Should you get the tools and study lock-picking?


Closers
Assorted sizes and shapes of opened can replacement "lids"
Opened wine / beverage bottle sealers
?Is there a way to re-seal an opened pull-tab beverage / food can?
Freezer grade, self-sealing, plastic bags
A few sizes of replacement locks / padlocks
A few sizes of cable / chain to pair with padlocks

What else in the way of openers and closers would help ensure you are "equipped to survive"?
