I need a gerda key for one of the blocks in my area. how do i know what key to buy. I.e H41 or H9.
I would just buy a master H key but they are so rare.

If its not written on the front, its usually enscribed on the lock barrel itself which unfortunately would usually be behind the door so you wouldn't neccessarily see it.. Depends on how they attach the lock to the door..

i could probably help you open this for a fee or even determine what key you need by the location and order you one if you want to inbox me

M8 if you can get hold of gerda keys I'm interested I'm after a h37 and h13
