Final answer:
The keys for detention doors should be either mogul or paracentric type, with paracentric being the correct completion of the given phrase as they offer higher security.

The question asks which type of key should be used for detention doors apart from a mogul type. The correct answer is that keys for detention doors should be mogul or paracentric type. Paracentric keys are designed with complex warding patterns that make them more difficult to pick or compromise,
Hence their use in high-security environments such as detention facilities.
