Your key looks like it’s a modern reproduction. There’s a lot of countries which continue to use basic and old fashioned techniques to produce ‘old looking’ items like jewellery, keys and artefacts aimed at tourists and export. Religious or celebratory inscriptions are common and even inscriptions resembling undecipherable hieroglyphics- which often turn out to be meaningless.
Looking at the bow (handle) of your key- it looks to still have the scale and flashing left from the casting process- this is normally removed from any casting as soon as it is removed from the moulds- on a genuine working key this would always be removed, cleaned up and polished afterwards- and in the unlikely event it was overlooked and left there originally, if it was genuinely old you wouldn’t expect it because it would have long since broken down and worn away after years of use and wear.
The bit of the key also resembles those typically found on ornaments- not what you’d expect on a working key that’s seen many years of use. Sorry about the bad news but I suspect the other key you posted with the figure is the same.
