4 wheel drive light blinking ????

its blinking 5 times in a row. thought it may have been my battery, so i let it run and ran it up and down the road a bit. i think if its the battery it will blink 4 times. turn the key off and started it back up and the light doesnt come back on. it started blinking 2 times today. any idea what it means when it blinks 5 times and doesnt stop untill you turn the key off and then back on????

just a side note-- i had to hot wire it about 2 weeks ago when i went to unload i found out i left my key at home. i just took the ignition switch apart and turned the base of it. ever since then i have o play with the key sometimes to get it to turn on, but the last few days its been fine. i'm still going to put a new switch in, its on order, but i dont know if they are some how related or not. anybody know what 5 blinks are ????
