Old phone game (Trying to figure out name)

[Andy that has problems]

Hello, everyone. I've been trying to remember, how one certain game looked like on one of my old phones, there was a farm game with cows and keys in different colors, you had to get some keys to open certain spots or something, doors maybe. Anyone knows what game that might've been? I'd say that the game was on, the 2000s range phones, maybe 2006-2008, maybe even before that. Thank you :)
