Have a variable that indicates the player's owned vehicle ID, check the example below. If a player buys a vehicle, the variable would be changed to the vehicle's ID.

For example:

pawn Код:

// place this under OnPlayerConnect()
PlayerStats[playerid][VehicleKey] = INVALID_VEHICLE_ID // alternatively, you can set it to -1

After buying a vehicle, set this variable to the vehicle's ID, in this case, the player needs to be on the driver's seat for him/her to be able to buy it.

pawn Код:

// this would be under the command for buying a vehicle
new vehicle = GetPlayerVehicleID(playerid);
PlayerStats[playerid][VehicleKey] = vehicle;

Now, for the lock, you'll have to get the player's vehicle position to determine whether it's within range or not.

pawn Код:

new Float:vPos[3];
GetVehiclePos(PlayerStats[playerid][VehicleKey], vPos[0], vPos[1], vPos[2]);

Checking if it's within range:

pawn Код:

if(IsPlayerInRangeOfPoint(playerid, 5.0, vPos[0], vPos[1], vPos[2]))
{

}

The code for locking/unlocking your vehicle:

pawn Код:

new engine, lights, alarm, doors, hood, trunk, objective;
SetVehicleParamsEx(PlayerStats[playerid][VehicleKey], engine, lights, alarm, VEHICLE_PARAMS_ON, hood, trunk, objective);

The code above would lock the vehicle, you can change the "doors" parameter to VEHICLE_PARAMS_OFF for unlocking it.
