This issue comes up a lot in aviation because you start with a new plane, all locks use the same key, and then one of the locks gets changed and you need different keys.
This company seems to be able to make KESO (and probably most other) keys using counterfeit non-KESO blanks, so you don’t have to prove you are the original owner (which can be impossible with say a 30 year old aircraft) 
Do you read cyrillic ??? I dont … ;-)
Can they also re-engineer locks to existing keys ?
The page google translates OK enough to read.
I did the alphabet as part of the mandatory Russian at school, but we all hated the commies (you weren’t allowed to say that!) so learnt as little as possible
I am sure they can make a lock to work with a given key; that is an absolutely standard locksmith function. I used to pick locks when I was a kid – fascinating things
I once flew back into Stapleford having left the keys to my Ford Escort behind in France. Oh despair!
“Not to worry” said the resident engineer. “It’ll open with any Ford key”. It did. But what about the steering lock? He sat in the driver’s seat and grasped the wheel. A sharp flick, a bang behind the dash, and voila! Unlocked! The hot wiring even I could do, and we were on the road in less than 10 mins.
Most aeroplanes that I know have keys of a similar vintage.
I’ve got keys copied at the usual shopping mall outlets. Including for newly bought switches from aviation outlets.
If you can remove the lock they can usually reverse engineer the matching key. Removing the lock in a pain in the butt. Local locksmith was able to CNC cut an exact Cessna key from codes on the lock. He looked it up on a database of keys. I gave him the ignition, front door lock and cargo door locks and he got them perfect. Ignition and front door on one key. Cargo door on another.
We lost the key to my wife’s Grumman Tiger in Boulder, Colorado. We went to the FBO, who gave us a huge box of random keys to try, and we tried different keys till one of them worked. I think we found one that worked on the 3rd or 4th try.
I once flew a Robin to the next airport (a 20 minutes flight) dropped the keys in the letter box for the maintenance guy to be able to open and to the checks on it, flew back as a passenger on one of the other plane of the club, sat in my old 2CV only to realize that the keys I had dropped were the one of my citroen 2CV ! No problem, the 2CV worked perfectly fine with the keys from the Robin (Robin had used a 2CV door locked mechanism :-))
I did not want the mechanic guy to have any trouble so, using a more modern car, I drove to the maintenance and dropped the airplane’s keys.
A week later, I got the keys of the 2CV back when we got the plane was serviced and back in operation. I do think the plane would have worked fine with the keys from the 2CV but I’ve never tried.
You don’t even need a key to open many Cessna’s even if they are locked….

Unless they’re locked from the inside. Once the door handle of a C172 fell down as I closed the door, making it impossible to open the door from the outside. I had to bribe a nearby 5-year old with ice cream to crawl in through the baggage hatch and open the door from the inside. All with permission of the accompanying parent, of course. :-)
