Dormakaba DF59 – Frequently Asked Questions

1) What is the Dormakaba DF59 control key used for on a Simplex pushbutton lock?
The DF59 is the control key that opens the access lock on the back of a Simplex 1000 series pushbutton lock, which is what you have to open to change the combination. It is not a key that unlocks the door for entry. If you manage a building on Simplex locks and nobody can change codes anymore, this is the key that went missing.
2) Will the DF59 key work on a Simplex 1000 series lock?
Yes. The DF59 replacement keys fit Simplex 1000 series pushbutton locks. That is the series they are cut for, so if the lock on the door is a 1000 series mechanical pushbutton, this is the right control key.
3) Is the DF59 the key that opens the door, or a different key?
Different key. The DF59 is a control key, meaning it opens the rear access lock so the combination can be changed. Entry on a Simplex 1000 series is by pushbutton code, not by this key. If you are trying to get through the door, the DF59 is not what you need.
4) I lost the key to change the code on my Simplex lock. What do I order?
Order the Dormakaba DF59 replacement control key set. Losing that key is the usual reason a Simplex 1000 series lock gets stuck on an old combination, since the rear access lock has to be opened before the code can be changed. The DF59 set restores that access.
5) How many DF59 keys come in an order?
The DF59 ships as a set of two keys. Most property managers keep one in the office and one with whoever actually rotates codes, so a single order covers both without a second purchase.
