Cheap/secure/convenient locking for outswing pair of garage doors?

[WaterproofBanjo]

The doors on my single-car garage (actually zero-car, multi-tool, multi-bike garage) are approaching end of life, and it's time to re-do them.

The doors are basically a set of outswinging French doors (minus the windows).  Hinges on both outside sides, no center column.  The current locking "system" is a piece of L-channel steel on each door, with 2 padlocks going through holes drilled in the steel.

We have a set of Andersen French doors on the house, and I really like the multi-point lock system on them.  Pulling up on the active door's handle engages upper and lower "hooks" which hook into the passive door.  Pulling up on the passive door's handle shoots bolts into the upper and lower door frames.

My first choice would be to buy the identical lock system and install it on the replacement doors I'm building.  But that'd be $280 for the lock hardware, plus another $150+ for the "trim" (i.e. handleset).

I know I'd like how it works, and I'm in and out of those doors all the time, so I want it to be convenient.  I also really like my tools and bikes, and want to keep them secure.

Before going in this direction, do any Mustachians out there have alternative ideas for cheap, secure, and convenient locking of doors like this?

Do you open and close both doors all the time, or just one? If just one, you could put sliding bolts on the top and bottom of one door and a normal door handle on the other one.

Or you could go this route.

Thinking about it, I'd say 75% of my access only requires one door, so I suppose the bolts-on-the-passive-door approach would work.  I've just always opened both because that's the way things worked already...

The woodgears approach is also awesome.  The pointed-to version doesn't appear to actually lock, though I can imagine how you could implement a lock with a deadbolt that shoots into the bar to keep it from moving.

Thanks for the ideas!
