I'm planning to upgrade the whole lock mechanism on an armored door.
The lock that is installed at the door now is exactly like this one

I live in Greece so we usually replace this kind of locks with locks that a Europrofile cylinder can be installed on them.
The owner is a 85-90 years old man and asked me for the most secure Europrofile cylinder I could get him.
I'm mentioning the age because it has to be something easy to use.
I would buy an abloy protec2, which I trust a lot but because I use one and I know that getting the key out of it, is not as simple as with most cylinders, I'm thinking for alternatives.
Also an escutcheon from DiSec(BD200) will be installed to protect the cylinder.
Some high security cylinders, available in Greece:
-Abloy Protec2
-Dom Diamant
-Kaba experT
-Keso 4000s omega
-Cisa RS3s
-Mauer NW5
I think Dom Diamant is a bit overpriced for what it offers so from the rest above I'm leaning towards to Kaba expert.
Kaba expert is great but as long as I know it can be picked or bumped. I'm not worried about picking that much but bumping..?
Should I proceed with abloy protect2 and get the old man pissed of until he gets used to it or you guys think I should choose another cylinder?
Any suggestions are welcomed.
Thanks for your time,
George
