Imbue Item (Su): A warlock of 12th level or higher can use his supernatural power to create magic items, even if he does not know the spells required to make an item (although he must know the appropriate item creation feat). He can substitute a Use Magic Device check (DC 15 + spell level for arcane spells or 25 + spell level for divine spells) in place of a required spell he doesn’t know or can’t cast.only issue I have is that a warlock doesn't know any spells, and Craft Contingent Spell isn't a magic item, it's literally a spell effect, so a warlock, by literal reading of the rules, can't use Craft Contingent Spell - he doesn't know any spells.
If the check succeeds, the warlock can create the item as if he had cast the required spell. If it fails, he cannot complete the item. He does not expend the XP or gp costs for making the item; his progress is simply arrested. He cannot retry this Use Magic Device check for that spell until he gains a new level.

[Item Creation]
You know how to attach semipermanent spells to a creature and set them to activate under certain conditions.
[h=4]Prerequisite[/h]Caster level 11th
[h=4]Benefit[/h]You can make contingent any spell that you know. Crafting a contingent spell takes one day for each 1,000 gp in its base price (spell level × caster level × 100 gp). To craft a contingent spell, you must spend 1/25 of this base price in XP and use up raw materials costing one-half the base price. Some spells incur extra costs in material components or XP (as noted in their descriptions), which must be paid when the contingent spell is created. See Contingent Spells, page 139, for more information.
