Battery died on Sandleford n15115. How do I open? HELP

Use the emergency key, that is what it is for.

Or you can open it with a large puck magnet.

Install fresh batteries.
Press reset button on left side of door (may be covered with protective plastic cap), beep will sound.
Enter new 3-8 digit code, press * or # key, green light will come on to confirm new code accepted.

It could be the wrong key for this unit. Maybe you need to shake it a bit. What type of key is it?
