Locks
One of the best locks on the market is ABUS Granit X-Plus 540 + USH Brkt 300mm LS Shackle U-Locks (Amazon link).
Fair warning about choices regarding this lock.
1) It's 3 or 4 lbs.
2) It comes in two different hasp lengths. This is the long one (9") so you can fit it around any of the larger body tubes on your trike and around a somewhat larger sign post or bike rack.
3) You can order it with or without a way to mount it on your trike/bike. The mounts come in 2 different sizes (for the mounting tube diameter). I ordered the larger one and then decided to mount it on my spouse's rack (smaller tubes). It's OK, but not quite tight enough for my liking. Trike is a 20" Titan Trikes Terrain. The lock gets locked into the mount.
​
This lock is lighter than every other lock on the market with the same security rating. I know that's not a big deal for us trikers but thought I'd mention it. The hasp locks on both sides and you remove the hasp when you unlock the lock. I highly recommend finding some reviews on this lock and checking it out.
This might not matter to you, but given that I have 3 cyclists (maybe 4 soon) it's a convenience that I can order multiple locks from Abus that will all come with, and use, the same key.

Repair Kits
Your best option here is to go to your local bike shop, tell them what you have and where you expect to be riding.
They are just much bigger and there's more you can latch onto for security. Again - I wouldn't leave them anywhere sketchy nor would I ever leave them overnight.
Basically, you can use a sturdy U lock and a thick chain to secure the frame and both tires to the rack. Then you can buy special locks for your wheels, seat, and handlebars so that people can't steal your shit with a simple Allen wrench.
This is an e-scooter forum so don't want to sound like I'm shitting on them, but their mobility is also what makes them so damn easy to steal. To steal my e-bike you'd have to cut through this and this, which would require time, tools, and would make a shitload of noise.
For the same price you can get this bad ass mamma jamma. It requires both sides of the shackle to be cut for the lock to come off.

The Granit looks interesting I'll check it out:

I didn't realize that insurance companies rate your locks. I have renter's insurance and they didn't mention anything like that in the terms.
I mean, I guess I could also just look at better locks. Something like this could work well.
