Replacing euro lock/ what is the brand from my key number?

[awasawas]

I have lost my UPVC door key.
I need to change the lock.
I know how to do this but would like information on the make as I would like to keep to the same manufacturer and also will not have to measure the length of the lock.

The key has HD in capitals and underneath WM 88

Any suggestions please?
Thanks.

If you can manage to remove the old cylinder ... why dont you just measure it, and buy a replacement the same size ?
There is no need to buy the same make as they all tend to do the same thing.

Let us know if you have problems removing the old cylinder.
