Too many variables. What kind of locker? I think you can get an auto locker (a/k/a "Lunchbox locker") for around $250. A full ARB air locker with the air pump would run you ~$1200, I believe (I researched it a bit when I had my Taco, which had an unlocked diff.) For a Toyota E-locker off of a wrecked or salvaged 4runner it's probably somewhere in between those two extremes.

Lunchbox Locker - A "Lunchbox" locker (or drop-in locker) is a locker mechanism that is designed to fit into the stock differential carrier replacing the spider gear set and sometimes the side gears and pinion-shaft. The nickname "Lunchbox" comes from the idea of packing your lunch in a reusable "lunchbox" where you use the same "lunchbox" and pack in a different lunch. The stock carrier is the equivalent of the "lunchbox".
Lunchbox Lockers operate in much the same manner as full carrier automatic lockers. These locker are automatic locking differentials designed to lock both wheels of the axle automatically with power input, when forward or reverse torque is applied, so that both wheels are providing 100% power to the wheels and creating essentially a "spool" that solidly connects the axle shafts together. When torque is not being applied, the locker is allowed to unlock, permitting a differentiation variance in wheel speed while negotiating turns.

The labor is a lot for the ARB as well as the parts. ARB ~$800, compressor (small) ~$160 or (big to run 2 lockers and fill tires) ~$260, and install would be about a full day to install the in the diff, drill the air hole and pipe it in, and install and wire the comp and switches. Keep your eyes open for the ARB "buy a locker and get a free compressor" deal they have going once in a while.
