Are all the keys for gullwing windows alike, or does each have a unique number?
We have 250 key numbers available, which we use in sets of 50 to avoid excessive duplication of the same key numbers.
If you order multiple gullwing windows in a single purchase, we'll ensure that you receive matching keys for all your gullwing windows. However, if you later decide to order an additional gullwing window, you will need to order new locks if you wish to have a single key that operates all your windows.
