1. For a start, I don't think you can get Nilesat which is the satellite on which you find Showtime and ART (or otherwise Badr 26e or even Hotbird); so keys for the Showtime or ART packages are of no use to you.2. The one station in Naija for which most people can use a key is eTV on 68e (same satellite as MyTV)3. How to insert keys will depend on your particular receiver; but you need to know some basics as explained below.(a) TV providers who encrypt use different encryption systems e.g. Nagravision, Conax, Viacess etc(b) Some of these encryptions get compromised and 'keys' become available for some providers(c) For a particular provider that is compromised you need to know the encryption system e.g. eTV uses Nagravision; you then need to know the Provider's ID (a kind of identifying code) e.g. 2011 or 2111 for eTV; you then have to know the particular 'active' key.(d) You then enter the keys into your receiver; however, first of all your receiver must be 'patched', which means it must have the right kind of software; (official software is normally useless for this purpose).(e) You enter the key into the correct space for the particular provider (using its correct ID), in the right encryption section (e.g. Nagravision), and in the right format i.e. 'hex' or 'dec' (in rows of 2 characters or rows of 3 characters).From here, to be able to help you further, you need to state what satellite(s) you can currently receive and what provider/channels you want to watch.
