Question: Arcane Locks, what are they?

[Rip]

Hey folks,
So I'm dm'ing a mod and I've come up on some doors within that are Arcane Locked. Sounds good...but I don't know what they are. The mod does not give it a DC nor describes what one is. The DMG & SRD has a section on doors and locks but nothing helpful on exactly what it is or entails. My game is message board and details are the utmost importance.
So roughly my questions are:

1. What sort of unique descriptions can I give each door the group encounters that are arcane locked? They are not magically trapped.

2. Can a rogue unlock it? and how? Are we dealing with actual locks or is it a variety of procedures needed to open one? passwords, special keys, etc.

3. What DC ranges would you give an arcane locked door.

Thanx.

Arcane Lock is a 2nd level arcane spell. The descriptive text in the PHB should answer most of your questions.

Here are the details for your convenience:

Arcane Lock
Abjuration
Level: Sor/Wiz 2
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: The door, chest, or portal touched, up to 30 sq. ft./level in size
Duration: Permanent
Saving Throw: None
Spell Resistance: No
An arcane lock spell cast upon a door, chest, or portal magically locks it. You can freely pass your own arcane lock without affecting it; otherwise, a door or object secured with this spell can be opened only by breaking in or with a successful dispel magic or knock spell. Add 10 to the normal DC to break open a door or portal affected by this spell. (A knock spell does not remove an arcane lock; it only suppresses the effect for 10 minutes.)
Material Component: Gold dust worth 25 gp.

Ah silly rabbit! Now that would explain everything now wouldn't it.

Thanx much!!
