I just googled Supra combination lock boxes and the one site I opened had directions on it for several different styles. If this link doesn't have what you need, just go back to google.
Hope this helps - See you in the office.
Combination key box "door only" for Supra key boxes. Codes are changeable.
HOW TO OPEN YOUR KEYBOX
Pre-set factory combination is: S P I
1)Spin to the right 3 times to clear.
2)Stop on "S" (first letter)
3)Turn left past "S" then directly to "P" (second letter) amd stop.
4)Turn right directly to "I" (third letter)and stop.
5)Push button down and pull lid out from vault.
Do you have someone that can help me?
I appreciate your prompt response.
You will find the "Installation Instructions". Then get the " Spin Dial Instructions" to view and download the pdf. Go to: http://www.gesecurity.com/portal/site/GESecurity/menuitem.f7 You can't tell the players without a program.
