Remote Central locking
There are many types of aftermarket modules, some doing a simple lock/unlock, others also activating horns, lights, alarms, etc.
So I'd suggest searching for "how to wire car locking module," then checking out the results (including many YouTube videos).
However, you'll probably install the unit inside the driver's door panel, because that door's exterior lock and interior lock button give orders to the locks in the other three doors.
Then, use a circuit tester to identify:
--one wire that is always hot, whether the engine is on or off. This will usually be colored. This wire should be connected (use a crimp-on connector) to the power supply for your aftermarket locking module.
--a black (usually) ground wire, that should be connected to the ground wire on the module.
--one or more trigger wires running from the lock switch on the door. There are different types of trigger setups and different ways to connect them, so there may be some trial and error involved. When you've got everything hooked up, though, make sure the "lock" button on your remote makes the doors lock (and vice versa for the unlock button). If the commands are reversed, simply swap the control connections.
--if your new module also has the capability of making your horn sound and your headlights and taillights flash ... well have fun. You'll have to figure out how to hook up the wiring on the module to the headlight and taillight circuits, which won't be obvious or easy. Personally, I'd skip that part and be happy with the remote lock/unlock.
